Drywall

The old wall was made of plaster about 7/8" thick. I bought the 5/8" Fire-Shield board to replace it. The problem in putting up thinner drywall is that I had to level off the area where the new drywall met the old plaster (kitchen/dining room connection). In hindsight, I should have used small strips of wood to build up the wall beams to make up the missing 1/4". Instead, I needed to apply 5 layers of joint compound to slowly level off the drop. This was a high visible area of the room, so I wanted to make sure it looked seamless. I was happy with the results in the end.
