Final Inspection – July 2025

The countertop installers arrived on the first of the month. The started by placing the slabs on the base cabinets. The granite countertop, where the cooktop will be, was delivered with the opening for the cooktop not fully cutout in order to retain its integrity during transport. This can be seen if you look closely at the area the guys are facing in the image below, where they were preparing to cut that bit out to open up the space for the cooktop.

Slabs Placed on Base Cabinets

Here it is ready for the cooktop.

“Black Absolute” granite Installed

As for the island, there was a bit of a problem. At either end there is a hole for a 3″ popup outlet, (you can clearly see one of the holes in the first image above). While cutting one of the holes, they slipped, leaving a mark just outside the hole. They were hoping that, once installed, the part of the popup outlet that sits on the countertop would cover it up, but it did not. So this could have been a big deal, meaning the slab would have to be replaced. Before doing that, we decided to order a larger popup outlet (4″), expand the hole, and see if would cover the blemish. I was very skeptical that it would work because below the countertop there was very little room to expand the hole. That is, the hole was very close to the back of one of the cabinets, so I didn’t think there would be enough room to accommodate the collar that screws onto the outlet from below the countertop to secure it. Since the alternative was to scrap the blemished slab, there was no harm in trying. So we ordered a single larger popup outlet and waited for it to arrive.

In the meantime, I returned my attention to the ducting that would vent the cooktop exhaust out of the house. In my last post, I had installed the small cabinet above the cooktop and originally planned to use flex pipe to connect it up, as shown below.

Flex Pipe Venting

Unfortunately, this wasn’t going to work as you can see from the image. Not only that, but you’re not supposed to use flex pipe in this situation because the ridges in the flex pipe increase resistance to airflow, providing a better opportunity for grease to accumulate. I learned this by accident during a conversation with the guy who installed the wall oven. Given this, I sought to have custom ducting created to replace most of the flex pipe, as mentioned in my last post. I would not be able to replace all of the flex pipe. The portion that is above the cabinet and extends to the roof is no longer accessible, so it would have to remain and the new ducting would have to connect to it at the top of the cabinet. That, I believe, should be fine because the primary area of air flow resistance will be in the bend within the cabinet. Once the air exits the ducting within the cabinet, it is a straight run to the roof and out of the house. Fortunately, the custom vent ducting was completed at the time we placed the order for the new popup outlets, so I could switch over to that task while I waited. Unfortunately it wasn’t quite right, requiring a trip back to the fabricator.

In the first image in this post, notice that there is no longer a cabinet above the cooktop countertop. I removed this because I needed to take it with me when I returned to the fabricator so they could see exactly what the ducting needed to fit into. I should have done this in the first place, but I hated to have to remove the cabinet. In the end, it was the right thing to do, and they got it right when I did.

Exhaust Ducting In Place

Above you can see the cabinet back in place and the new custom ducting in position. Here it is after I secured it in place.

Exhaust Ducting Secured

The wood underneath the ducting was placed there just for extra support. The outlet of the ducting is tied to the flexible pipe that extends out the top of the cabinet to the roof. It is secured using a metal hose clamp, as shown below.

Ducting Secured to Flex Pipe with Hose Clamp

This turned out to be a much bigger challenge than I ever imagined. It was a tight squeeze, so I was very relieved that it worked out.

With the ducting secured, it was time to lift the exhaust vent into place and secure it to the bottom of the cabinet with four screws. I had a couple of friends help with this.

Getting that done was a big deal. I was so happy to have it checked off.

The next day the larger popup outlet arrived. They ordered a gray one because the white color, for some reason, would take longer to arrive. Since this was just to try it out, the color didn’t matter, so they ordered what would get here the fastest. They would return it once we’d determined if it would work. With the wider popup outlet in hand, the guys got to work widening the hole. To my pleasant surprise, it worked, and we did not have to replace the slab. So the guys could start setting the seam between the two slabs. In the image below you can see the equipment used to pull the slabs together. You can also see the gray popup outlet in place at the end of the slab.

Setting the Seam

Once aligned to their satisfaction, glue is applied and the two seams brought together and left overnight (Thursday, July 3rd).

Seam Set

The two white popup outlets were expected to arrive on Saturday, July 5th, so there was a day in between, July 4th, that I used to install the refrigerator before I headed out to celebrate Independence Day.

Refrigerator Installed

The next day the guys returned to finish the installation, which involved polishing the seams, installing the undermount sink, and cleaning it all up. After they left, I put in the faucet and the pressure switch (to the left of the faucet) that will control the in-sink garbage disposal.

The two white popup outlets arrived the next day and I put them in place and plugged them into the outlets below the cabinets.

Popup Outlets Installed

Note that these outlets also provide USB ports and can charge a phone by simply setting the phone on top of the outlet, whether popped up or not.

With the countertops and sink installed, I arranged to have a plumber install the plumbing for the sink and install the dishwasher. I entertained installing this by myself, but it would be a complicated install. As I later discovered, this was a good call, which you’ll see shortly. But before that happened, the mirror for the the master bathroom vanity arrived and was installed.

Vanity Mirror and Lights Installed
Vanity Mirror and Lights Installed – lights on

The interesting thing about this installation was that the company insisted that they install the vanity lights. Since the lights are on the mirror, they did not want the customer to mess with it for fear that if they over-tighten them, it could break the mirror. So I was completely hands off for this, which was fine by me. It was a two person job, as you’d expect, and took about two hours. I like it.

A couple of days after the vanity mirror was installed, the plumber arrived and hooked up the supply lines to the sink and dishwasher, the in-sink garbage disposal, and the drains for all of it.

Plumbing Under the Kitchen Sink

As you can see, there is a lot going on here. We decided to locate the garbage disposal under the large sink because installing it under the smaller one would have meant that the drain from it to the main drain would be too steep a slope. When too steep, the water separates from the solids too quickly, which can result in clogging.

Below I am showing a closeup of the P-trap. The large sink drains through the garbage disposal into the drain under the small sink, where the P-trap resides. The output of the P-trap connects to the main drain that continues under the concrete slab and out to the street sewage system. Behind this you can see a black box plugged into the outlet. Into the black box is plugged the garbage disposal. This black box connects to the pressure switch above the countertop (shown in a previous image above), which, when pressed, switches the garbage disposal on/off. The plug below and to the left is for the kick plate lighting, which was discussed in a previous post.

P-trap Under Small Sink

Below you can see the where the drain emerges from below the cabinet. At the top of it is a Studer Vent. Plumbing vents act as pathways for air to enter and exit the drainage system. This helps maintain balanced air pressure, preventing a vacuum from forming that could hinder water flow and cause drainage issues. They are normally inside a wall cavity and extend out through the roof of the house. Since this is not available in an island, the Studor vent comes to the rescue. It provides the venting function while preventing sewer gases from escaping.

You can also see below that a water hammer arrestor (the copper thing) is installed along the water supply like for the dishwasher. This is needed because the dishwasher will turn the water on and off suddenly, which can result in “water hammering”. So this device will prevent that.

Water Supply, Drain, and Power for Dishwasher

Finally, here is the thing everyone sees; the dishwasher.

Dishwasher Installed

With this done, I have a functioning island. The last thing required to make the kitchen fully functional was the installation of the cooktop. However, before that could be done, I needed to add a backsplash on the wall behind where it will go. I intended to add white tile with black grout to that area, but after a warning from the tile supplier about how difficult it will be to keep clean I decided to abandon that plan and instead extend the black granite up the wall. There is likely to be a lot of splatter on that wall, and granite with no grout lines will be much easier to clean. That decision, however, meant that I would not be installing the backsplash anytime soon. The granite will have to be sourced, and the fabricators will have to do their thing, etc. The backsplash, however, is not something that requires an inspection, so I went ahead and installed the under counter lighting, cooktop, and outlets in that area so that I could schedule an inspection.

Cooktop, Outlets, and U/C Lights Installed.
Closeup of Cooktop

As you can see, the outlets are black, so they will blend in with the black granite once it is placed on that wall.

I ordered the cabinet pulls for the kitchen. The ones I liked were surprisingly expensive, but I got them anyway. Apart from installing the backsplash and cabinet pulls, my work in the kitchen was done, for now. My inspection was scheduled for Monday, a few days from now. So I turned my attention to the guest bathroom, installing the shower head and wand.

Shower Head and Wand Installed in Guest Shower

There is a bit of a story with this. Both the shower head and wand have separate water supply lines. Each line connects to a “bent ear elbow” behind the wall. When I positioned the two elbows, I estimated where they should go. Unfortunately, I set them back too far, meaning the threads for both the shower head and wand holder could not reach them. This was not an issue for the shower head because I was not keen on the rain shower head I had purchased. It was kind of fancy and attached to the wall with an extended version of the holder for the shower wand. More than that, though, I wanted a shower head that was not limited to just a rain head. So I decided to replace the one I had with one that had both a rain and a traditional stream (achieved by rotating the shower head). This also came with a traditional shower arm, which meant it would easily reach in and connect to the recessed elbow. It was not a perfect color match, but close enough.

Shower Head

However, there was no such option for the wand. The threads of the wand holder were not long enough to reach the threads you see in the image below.

Drop Ear Elbow Recessed behind the Tile

To fix this, I purchased an adapter to bring it out to the level of the tile. In the image below, you can see that it actually comes out just beyond the surface of the tile, but this is well within tolerance because the flange for the wand holder would cover it.

Adapter Added

Unfortunately, the threads of the wand holder were too long and, when fully seated in the adapter, the holder extended too far to be covered by the flange.

Threads too Long

As it was, this was unusable and looked like I’d have to replace it. After some thinking, I decided to try cutting off some of the brass threads. Since I figured I was going to replace it, I might as well give it a shot. So I pulled out a hack saw and sawed off a section, careful to keep the threads in tact.

Cutting the Brass Threads
Section of Brass Threads Removed

Although it looks a bit messy, I didn’t have to do any work with a file to clean it up. The threads engaged nicely with the threads in the wall, resulting in a nice fit. It protruded just a bit, but that was easily covered by the flange, as you can see in the image below.

Shower Wand Installed

I was pretty happy about this. I thought this was going to be a major headache. To have it come together like that was very pleasing.

My cabinet handles arrived, so I got to work installing them. I installed all but the ones that will be going on the cabinet doors that I am having replaced. A few of the doors had defects. Given that there is a 5 year warranty, the company has been notified and they will eventually send me replacements. So in the images below where no handles are present, those are the doors that will be changed out once the new ones arrive.

Handles Installed
Handles Installed

Note that on the other side of the island there are also cabinet doors, but they will not be getting handles because those cabinets will rarely be used and adding handles might present an obstruction for ones knees while sitting at the counter. They can be opened by pulling on the bottom edge of the door, when needed. Also, from the vantage point of the living room, I think it looks better without them.

My inspection resulted in the approval of the electrical and mechanical. The plumbing and final inspection had to wait because the inspector had trouble finding the stamp on the glass wall of the master shower that shows it is tempered glass. That was resolved the next day, so I scheduled another inspection, which resulted in the approval of what was remaining. So I am finally done with inspections, which is a really big deal. I am free to move in when I’m ready and can proceed with whatever project suits me without regard to permit expiration dates.

The lease on my apartment ends mid November, so I will use the time between now and then to work on anything I feel I’d like done before I move it. However, I am at the point now where I could move in because the remaining projects are ones I can and will do while living in the house.

The timing of this worked out well, as I am going on vacation for about ten days. So it’s a nice way to start that. When I return, I think I’m going to focus on the garage and setting up the workshop I need to address the upcoming project. That will be fun.

Drafting Table Top – September 2024

Since I was no longer driving toward a mid November move in date for the house, I decided to indulge myself with another side project. I actually started this while working on the wall repair in the master bathroom I documented in the last post, but did not complete it until this month, so I chose not to mention it in the August post.

When I was in high school I built a drafting table.

Drafting Table – Original Top.

The top was made from particle board with a solid wood edging and covered with a thin green vinyl sheet. I currently use it to support my computer monitor and keyboard. It is sufficient, but the vinyl covering is not very flat anymore. In the image above you can see the “bubbled” areas by the mouse. I have managed with this, but is a bit of a nuisance. Here is another view from the front.

Drafting Table – Original Top.

I was thinking of replacing the vinyl cover, but then I got the idea that I could build a new top from the remaining furring strips I had lying around in the garage, making a kind of butcher block desktop. Since the job of fixing the bowed wall at the entrance to the master bathroom required that I wait for each application of drywall mud to dry overnight (see the July/August post), I used the extra time to start on it. Here is a shot of the furring strips I would use. I had just cut them to rough length. They are not arranged in any particular order yet.

Drafting Table Top – Pieces cut to Rough Length.

The top needed to be less than 45″ wide to fit in the space I had, and I wanted a depth of around 26″. The dimensions weren’t that important, so I kept those numbers in mind, hoping I had enough material to get close. Maximum yield was what was really driving the dimensions, as long as I didn’t go over the 45″ width. As you can see from pieces on the left in the image above, I didn’t have enough full length pieces to make the depth I wanted, so I had to introduce six rows of two-piece strips to get to about 31″, knowing that I would plane a good bit off in preparation for glue-up, which would hopefully leave me with around the 26″ I was looking for.

Drafting Table Top – Beginning Glue-up.

Before glue-up I had to pull a lot of staples and a few nails and screws from these boards. Remember, they used to be attached to concrete blocks (using nails), were covered with an insulating material (attached using staples), and had drywall screwed into them. Once they were “clean”, I could run them through the thickness planer to smooth out the faces that would be glued together (what you see above). After planing, the depth was reduced to about 25″. Since my thickness planer can only accommodate 13″ wide boards, I divided the stack of strips into three sections, each no more than 9″ deep and organized them in a way that looked aesthetically pleasing. I distributed the lengths that were composed of two pieces evenly among the full length strips and marked them so I could maintain their relative positions.

During glue-up I further subdivided each section into two in order to make the glue-up more manageable. This is shown above. Once each of these subsections was cured, I glued them together, which is what you see below.

Drafting Table Top – Combining the two Subsections to create the first Section.

I left the glue to set overnight. The next day I pulled off the clamps and ran it through the thickness planer to get it close to final dimensions, then squared off the ends.

Drafting Table Top – Cleaned Up on Thickness Planer.

The final thickness would be established once I did the same for the the other two sections. Once they were taken to the same state as what you see above, I would run all three through the thickness planer, one at a time, to ensure they were of the same thickness before gluing the three sections together. Here are the other sections in clamps, ready to set up overnight.

Drafting Table Top – the other two Sections glued up.

And here they are after running them through the thickness planer, making them all the same thickness.

Drafting Table Top – Three Sections Planed to Thickness.

Since the combined width is greater than the capacity of my thickness planer, extra effort was needed to ensure they aligned properly as I brought them together. To help with this, I used dowels, referencing their location relative to the top (show) face.

Drafting Table Top – Dowels used to align the three Sections.

Then it was time to apply the glue and clamp the three sections together.

Drafting Table Top – Glued and Clamped.

The next day I removed the clamps and scraped off the glue that squeezed out from between the seems. I also place a straight edge across the top to see how flat it was. As you can see from the image below, there was significant cupping. This was largely due to my forgetting to place clamps at the seems. A stupid mistake that resulted in far more hand planing (see below) than should have been needed.

Drafting Table Top – Cupping

Although this does not have to be perfectly flat, I had to do something about this. So I pulled out my number 7 jointer plane and got to work.

Drafting Table Top – Removing the Cupping.

This took considerable effort, leaving plenty of shavings on the floor.

Drafting Table Top – Many Shavings to Flatten Top.

In the end, I didn’t get all of the cup out, but I got it to a state I was comfortable with. To flatten that extra bit where the light shines through (see image below) would require the removal of so much more material that it wasn’t worth it. This would be fine.

Drafting Table Top – Cupping mostly removed.

And here it is after completing the flattening work.

Drafting Table Top – Flattening Complete.

Although it looks pretty good here, I still had a couple of things I wanted to do to it before applying a finish. In order to have no end grain showing I would put an edge around it with mitered corners. I would also use an epoxy resin to fill in any holes. These boards were pretty rough at the start of this, so there were plenty of nail holes, screw holes, and imperfect edges. After the milling process and the hand planing, some of these things were cleaned up, but others were exposed. Using an epoxy resin with a color tint would get it to the state I wanted. But first, I added a solid wood edge around it with mitered corners.

Drafting Table Top – Edging Clamped in Place.

The next day the clamps were removed and I cleaned it up using hand planes and a sander in preparation for the epoxy.

Drafting Table Top – Prepped for Epoxy.

I thought it was looking pretty good at this stage, and I hadn’t even applied any finish. Here are a couple of additional shots.

Drafting Table Top – Prepped for Epoxy.

With the solid wood edge added, the final dimensions came out to 43 3/8″ by 26 3/8″, which is right in line with what I was after. So I took that lovely looking thing you see above and did this to it.

Drafting Table Top – Epoxy Applied.

At this stage it looks like I’ve spilled coffee all over it. But that is just part of the process. The bits that overflowed the areas I intended to fill will be planed and sanded away after the epoxy has cured. Here is a closeup of an area.

Drafting Table Top – Closeup of freshly applied Epoxy.

The epoxy comes clear, but I added bronze mica powder and a bit of black to tint it. I’m happy with the color. The next day I planed then sanded it, then added a second application to a few areas that needed it. Once that was cured, I planed it off and sanded it all in preparation for finishing. Here are a couple of shots of it ready for finish.

Drafting Table Top – Ready for Finish.
Drafting Table Top – Ready for Finish.

To finish this, I decided to use shellac. I’ve not used shellac before, but have heard a lot about how great it is. So I bought shellac flakes and mixed up only enough for this project. Shellac has a shelf life, so I did not want to buy it premixed, since whatever was left over would almost certainly go bad before I’d be ready to use it elsewhere. I took a picture of the surface as I was just starting to apply the finish so you could see the difference.

Drafting Table Top – Finish Being Applied.

Here it is after finishing the first coat.

Drafting Table Top – First Finish Coat Applied.

It certainly darkened it a bit. I think I preferred the color before the finish, but not enough to redo it. Shellac dries very quickly, so you can put another coat on almost immediately after you have finished applying the previous coat. I put two coats on the hidden side, just so it was sealed, and eight coats on the exposed surfaces. I did not specifically choose to apply eight coats. That was what it took to exhaust the amount of shellac I mixed up. I was aiming for around ten coats, so eight was close enough. After the final coat of shellac, I gave it a light sanding with 320 grit sandpaper then applied a coat of paste wax to make it nice and smooth. Here it is after that.

Drafting Table Top – Finish Complete.

And here it is installed.

Drafting Table Top – Installed.

Yes, the base color does not match the top at the moment, but I will refinish the base one day after I’ve moved into the house. For now, this will do. Here are a couple of “after ” images that correspond to the “before” images at the start of this post.

Drafting Table Top – New Top.
Drafting Table Top – New Top.

I’ve been updating this post as I went along in this project, but it is only on this last update that I’ve been able to do it on my new desk top. I am very happy with it. My mouse has a much flatter surface to move over and I love having the extra space. This was a fun project, and I look forward to doing more of this kind of thing (woodworking, as opposed to construction) once I’m settled in the house.

Kitchen – May 2023

As I did in April 2023, I divided my time between work on the kitchen and master bathroom and, just like last month, I’ve created two separate posts. The work in May started in the kitchen, so it’s best to start with this post. Within it I’ll mention when I switched to working in the master bathroom, which you can choose to jump to if you wish to follow the sequence.

My concrete saw arrived right on time, but the blade took a week to arrive, which was frustrating. I was keen to get going. When the blade arrived I got right on it and started extending the existing trench at a 90 degree angle toward the small wall where the services would be. Below you can see that I removed half of the trench and am working on the second half.

Trench partially done.

I was happy with the performance of the saw. It is rated at 15 amps and I had it plugged into a 15 amp circuit, so I had to go easy with it, which I discovered the first time I tripped the breaker. It was a bit tricky getting into that corner. I got as close as I could. Here’s as far as the saw would take me.

Trench cut.

The next part would be tricky because I had to remove the concrete from under the bottom plate of the wall so I could feed the water and electrical lines down. I used my big honkin’ saw to get as close as I could, but resorted to a drill bit and cold chisel and hammer to get the rest of it.

Working on trench under Bottom Plate.

You can see how I used the saw to get as close to the bottom plate on the one side (cutting into the plate a bit) and how I used the saw again to give me a starting point on the other before resorting to the drill. I chipped away at this for some time using a hammer and cold chisel before giving up. So I went home to look into renting a small powered jack hammer. While exploring that option, I decided to buy one instead since I expect I’ll need it for the two showers too. So I picked one up from Harbor Freight and it made quick work of it.

Tench under Bottom Plate complete.
Trench under Bottom Plate complete.

Next, I cleared away the dirt to get at the existing drain and connected the new section to it, as shown below. The new section will come up into the bottom of the cabinet that will house the sink. The dishwasher, which will be located next to the sink cabinet, will also tie into this drain.

New Drain Installed

I placed a hose in the drain and ran the water for a while, feeling under the joints for any sign of leakage. The joints were well sealed, so no evidence of water around them.

Running along side the drain are the water supply lines for the sink (red and blue) and dishwasher (red).

Water Lines in Trench

Here they are coming down from the ceiling entering the trench. Note the bracing I added to support the lines within the wall.

Water Lines entering Trench

Here is another angle.

Water Lines emerging at Island

With this done, it was time to call for a plumbing inspection. I had to wait a day because it was the weekend, so I shifted my attention back to the master bathroom (see that post).

The inspection went well and I used the time to ask about how best to run the electrical lines to the island. Online there were differing opinions about whether one should use a conduit under a slab. After speaking with the inspector he said that no conduit was needed if you used underground feeder (UF) cable, which is what I was planning to use. This is considered fine for direct burial. However, he recommended I use a conduit anyway, so that’s what I did. So off to the store I went to pick up a 1″ conduit that would house 3 wires (two 12/2 wires – dishwasher and GFCIs, and one 14/2 for kick plate lighting).

A wire fishing line was required to pull the wires through the conduit. I pulled one at a time. The last one required a lot of effort because the space in there was getting limited. Here are the wires entering the conduit from the wall.

Wires entering Trench

Here they are en-route to the island.

Wiring En-route

And here they are emerging at the the island location.

Wiring at Island

The conduit was made up of a single 10 foot section of PVC and four 90 degree bends. They are glued in the same was as the drains. Before entering the conduit, I put the wires in their respective junction boxes ready to be hooked up. The wire for the dishwasher was not long enough, so I introduced a junction box in the attic where I spliced in a new length of wire that would reach the island. I wired it up and tested it.

So it was time to get this inspected. While waiting for the inspection I drilled the holes for the rebar. Rebar is needed if the width of the trench is over 22 inches, so I only needed rebar along the wide section of the trench. The part of the trench that runs along the wall is only 15 inches, so that does not require reinforcement. Shortly after drilling the holes, the inspector arrived and gave me the okay to fill in the trench, as you can see below.

Dirt added back to Trench

I had a couple of days to wait the pest control guy to arrive and treat the soil for termites, so I returned to work on the master bathroom. I also made a run to the store to get all the concrete I would need. I estimated seventeen 60 lb bags based on what I used in the master bathroom, which, coincidentally, was about the same amount of area to fill.

After the soil was treated, I prepared the trench for the pre-pour inspection, which was scheduled for the next day.

Ready for Inspection

The inspection went without incident and I began the process of filling in the trench with concrete.

And here it is finished.

Trench Filled

Here are a couple of closeups of the area where the services enter.

The next day it looked like this.

Trench Cured

You might be interested to learn that I used almost all of the seventeen bags I bought. There was very little waste, so I was pleased. After this I returned to the master bathroom to start removing the existing shower pan.

As mentioned in the post about the master bathroom for this month, I had a period where I had to wait on deliveries, so I decided to grind smooth the concrete I had poured in the master bathroom and kitchen. Here is an image of the trench in the kitchen after I smoothed it out.

Trench Ground Smooth

That’s all for the kitchen in the month of May.

Drywall, Level 1 to 5 – June/July 2021

In the first post about drywall, I neglected to explain what “Level 0” meant in the post title. I could go back and update that post, but now that I will be discussing level 1, I’ll just do that here. There are five levels of drywall finishing. For most of the walls, I will strive to achieve a level 5 finish. The levels are as follows:

  • Level 0: Simply hanging the drywall itself. No finishing at all.
  • Level 1: All joints and interior angles have tape embedded in joint compound. Excess joint compound, tool marks and ridges are acceptable.
  • Level 2: All joints and interior angles have tape embedded in joint compound and wiped with a joint knife leaving a thin coating of joint compound over all joints and interior angles. Only a single coating is required. Also, all screw heads have been covered with joint compound. Tool marks and ridges are acceptable. Achieving this level is good enough for the surface to receive tile or for a garage.
  • Level 3: Same as level 2, but an additional covering of screw heads, and tool marks and ridges must be removed. Achieving this level is sufficient when the surface is to be covered with a heavy textured finish, which will hide any imperfections. In my case, reaching this level on a ceiling intended to have a “knockdown” texture, is acceptable.
  • Level 4: Same as level 3, but an additional coat of joint compound is required to cover flat joints. Screw heads and accessories require three coats (an extra from level 3). This level of finish is sufficient for walls that will take a mat paint finish or will be lightly textured.
  • Level 5: Same as level 4, but a light skim coat is required to cover the entire surface. This level of finish is required when a smooth wall finish is desired and a non-flat paint is to be used.

In this post I will describe the work I do in the guest bedroom. As mentioned in the last post, I decided to stop hanging drywall after getting three of the rooms hung (almost – more on that later in this post). I decided to circle back to the guest bedroom and move forward through the levels so that I can gain experience that I can use when I move on to the other rooms.

I found a great YouTube channel called Vancouver Carpenter, which has helped me a lot That guy is a really good instructor. In one of his videos he discussed the need to prefill all joints before attempting to tape. Prefilling involves using a setting compound (as opposed to a joint compound) to fill all gaps. The idea is to have a surface that is ready to accept tape, where the tape will not get sucked into the gap. The setting compound contains a hardener and has minimal shrinking after drying, so it will be a pretty strong surface upon which to tape. Here is a before and after of the first wall I hung in the guest bedroom.

Notice that the setting compound is applied to all seems. The gaps between the wall and the ceiling are all filled. Even the factory edges (horizontal edges with bevels) are prefilled. For the vertical butt joints (non-factory edges), I use a utility knife to cut a small v-groove into which the setting compound will go. The claim is that by prefilling even the non-gappy seems, you will reduce the likelihood of cracks appearing later on.

Here are more images of the other walls. Although not required for level 1, I also covered the screw heads. It’s not pretty, but the gaps are filled.

Following this work, my order for 100 feet of mass loaded vinyl (MLV) for sound insulation arrived, so I set about putting it up on the remaining wall in the workshop; the one that borders the office.

First Portion of MLV in Place

I attached this using drywall screws and plastic caps from roofing nails. It worked well enough, but I switched to a screw with wafer heads for the remaining portions.

Next, I covered the MLV with drywall to finish the drywall hanging for the workshop. As alluded to in the beginning of this post, this was the true last bit of drywall I would hang before circling back to finish the drywall in the guest bedroom

After doing all this, it was time to determine if the MLV provided some level of sound insulation. To do this, I played a song on my phone and placed the phone behind the wall (in the office). I then compared what I heard with what I heard when the I moved the phone where no sound insulation was in place. Unfortunately, I did not notice any difference, which surprised me. So I will try using a different material next time and see if it improves things. MLV is expensive and hanging it is difficult because it is so heavy, so I am happy to try another material. But that will have to wait until I am ready to continue hanging drywall. For now, it is back to the guest bedroom.

I decided to address the opening in the ceiling of the guest bedroom first. We opened that area long ago to see why the ceiling and the wall in the corner were not straight. It didn’t really reveal anything obvious, so I decided to open it up further.

I discovered that the corner was poorly aligned due to some makeshift framing. To improve it, I added a few nailers (sorry, forgot to take pics) then patched it with drywall that would bring it closer into alignment.

Ceiling Patch, corner piece

By straightening the ceiling (it no longer swoops up to meet the adjacent part), the corner piece is a bit lower that the adjacent part of the ceiling it meets. I could not improve upon that without major surgery, so I will make the adjustments using mud (what they call “mud framing”). The patch looks kind of ugly right now, but it will be fine when I tape, mud, and finish it. You can already get a sense of it after prefilling the gaps.

After that dried, I started taping it.

After taping I applied my first cover coat.

One of the advantages of addressing the ceiling patch first, was that it gave me an opportunity to try taping and mudding in an area that will likely be covered by a texture (knockdown or skip trowel) and therefore more forgiving. After doing this I felt ready to start taping and mudding the rest of the seams in the guest bedroom, which will be less forgiving. Here are several shots of the result after applying my first cover coat. Note that while doing this I continued to add additional coats to the ceiling patch as I went along to smooth it out (more required, though).

One of the most difficult parts of this was the work required to tape the corners between the new drywall and the ceiling. This required that I scrape and remove the tape that was under the finished surface of the ceiling to make room for the new tape. I used a wet sponge to soften the dry knockdown texture covering the tape on the ceiling, then started picking away at it. Sometimes I would get a nice long strip to come off, but mostly it involved pulling bits and pieces. In the end I was successful and was able to apply new tape to the corners. It turned out well, but I’m not looking forward to doing this in the other rooms. I’ll search for a more efficient method when I get to that again.

To bring the walls to level 4, I required a second coat of mud. I did this in stages, applying the mud to one side of the inside corners first, then the other side the next day. I did some light sanding in between to get rid of any obvious imperfections and tool marks.

As usual, I added more coats to the ceiling patch. It’s just about where I want it now.

After applying the second coat and allowing ample time to dry, it was time to give it a good sanding in preparation for the skim coat (which would take it to level 5). To do this I used a pole sander and a hand held sanding sponge.

Here are some images of the result after sanding (level 4).

For skim coating, I tried a few different methods. I found another YouTube channel I liked (Paul Peck Drywall) that showed how he used a paint roller to apply the mud before using a 14″ knife to remove it. So I experimented a bit. I first tried using the trowel to both apply and remove the mud. Then I tried the paint roller and the 14″ knife. I did a bit of back and forth between the two before finally settling on the roller/knife approach. You can only use the paint roller when skim coating, because the mud is thinned down enough to make the roller work. When cover coating, you will not thin the mud (or only slightly), so applying it with a roller is not practical. I found that applying the mud for skim coating with the roller was faster and easier, so that became my preferred method. Perhaps I’ll change my mind some day, but at my current skill level, this works well.

North Wall first Skim Coat

I did this for all walls over several days, then started on a second skim coat for all walls. Between coats I did a bit of sanding, but after the second skim coat, I paid more attention to the sanding and finish. The second skim coat would be the final one before paint primer, so I spent a lot of time looking for imperfections and sanded them as needed. I also identified areas that needed a bit more mud and touched them up before the final sanding. Here is the result.

South Wall second Skim Coat Sanded
West and North Walls second Skim Coat Sanded
East Wall second Skim Coat Sanded

I’m happy with this. The real test will be how the walls look after the primer and paint are applied, but that won’t happen until I get the ceiling done, which is my next task and the topic of the next post. So until then…
