Coffered Ceiling – Tongue and Groove, August – September, 2020
The next step in creating the coffered ceiling was to fill in the middle part. That will be done with pre-primed tongue and groove pine then finished with crown molding. When I framed the coffers, I tried to make sure they was square and level, requiring shims between the frames and the joists. So after the frames were wrapped, I had a pretty good reference surface to work from. That is, the top of the vertical boards served that purpose. The picture below will show you what I mean.

The tongue and groove (T&G) would need to be nailed to something that would be a consistent distance from the top of each coffer so that the distance from the T&G and the bottom of the coffer was consistent (we want a straight line all the way around). To achieve that I attached nailers to the top of the vertical boards as shown above, being careful to align them with the top of the board. I also added triangular nailers in all four corners. They are arranged diagonally so that the center is open for electrical stuff while still providing a surface for the T&G. These nailers were fastened to the vertical boards and I used a lot of shims when attaching to the joists. Below you can see how the T&G boards go up.
The image on the right above is in the hallway by the guest bath. It was an irregular shaped area and was where the A/C plenum resided, so I had to improvise a bit with the nailers, but the same approach was used. The pictures below show them with all the T&G boards up.
Because I was going to be using crown molding within each coffer, I had the luxury of not having to extend each T&G board to meet the vertical board, hence the gaps. This worked out very well for me because I was able to cut each 8′ T&G board in half and get two fully usable pieces. Had I been more experienced at this, I would have thought about that ahead of time. I was very fortunate that it happened to work out this way. Imagine the waste if I had not been so lucky.
I continued in this way until I reached the end of the room. With the coffers filled in, it’s looking more and more like what I was after.
The rest of the month was spent filling in nail holes and gaps with wood filler followed by a lot of sanding. The prep work for painting will be significant, and can make all the difference. So I will be very diligent when it comes to that. The filling and sanding done at this stage is just a start. I’m sure I will go over much of it again when the time comes. During this time I also ordered the crown molding, as that would be the next step.
