A very exciting and grueling part of the remodel process is the installation of drywall on the walls. Unlike plaster, drywall comes in very handy 4×8 sheets of gypsum and is faced with paper or mold resistant paper as you see below. A common color for mold-resistant drywall is usually green in color and somewhat heavier than regular drywall. To normally hang drywall is technically a simple process of measuring your wall and cutting the sheets to fit into the spot needed, then using drywall screws, screw through the sheets into the wall studs behind it. Now, if every wall in your room is perfectly square and level, you will fly through this process in no time. If you are dealing with some new walls and some that are close to 150 years old, then you have a tough job ahead of you.
Below you will see the finished product of about 12 hours of “hanging” drywall. The goal of hanging drywall is to use as large of a sheet is possible wherever you can to limit the amount of seams between sheets. You want to keep factory tapered edges together and all butt joints together. You’ll also want to stagger all butt joints so you will never have 4 corners meet at one point. One of the last and I feel a really important step is to leave a slight gap between the floor and walls. Reason is for expansion and contraction of the house. If you find a piece of drywall really snug against the floor, it’s best to trim a little off the bottom so in the summer when the wood subfloor swells, you don’t end up with your drywall cracking under pressure.
I did take note of one problem that I ran across while hanging drywall that I didn’t realize was a problem until I was about to screw it in. The R-13 insulation that I added on the back exterior wall was not laying as flat as it should because it is made for a 15″ wall cavity. Since I had to add studs inside the cavity to straighten the wall, they were only 13-1/2″ wide. That caused the insulation to bulge slightly and when I went to hang the drywall it was keeping it from laying flat against the studs. It was a simple fix by taking away some of the extra insulation, but it was still an extra hour added to the process.
Once all the drywall is hung, the next step will be to tape and “mud” all the joints with compound.
