How To Replace Water Damaged Drywall

Drywall is usually the first thing that gets damaged where there is leaking in the wall pipes. When drywall gets soaked from the inside, it can often be hard to detect at first. But, water damaged drywall can start to sag and become very weak. This is why it is so important to fix water damaged drywall as soon as possible. In some cases it will be easier to just cut out the damaged part of the drywall and replace. This article explains how to change drywall on vertical walls.

Cut Out the Damaged Area

Cutting out a section of drywall is very easy with a simple drywall saw. These saws are small but sharp, and they cut through drywall very easily. However, you definitely don't want to cut through any pipes or studs. This is why you should find and mark potential studs and obstructions with a stud finder before you start cutting. You also want to take care when cutting out that your cuts are straight. Cutting out a square or rectangle will make it much easier to cut the replacement piece. It will also be easier to mount the new piece of drywall if you are able to mount the edges on a stud. This is why you should try to end your cut in the middle of a stud.

Cutting the New Piece

When cutting straight edges of a new piece of drywall, you do not want to use the saw. Instead, you should just use a utility knife. You can cut much straighter and cleaner lines with a knife. Score one side of the drywall, cutting about halfway through the board. Then, you should be able to snap the piece along the straight line. When making the cuts, you want the fit to be as tight as possible, so double check all your measurements.

Taping and Patching the Drywall

The final step is to attach the drywall to the wall. Using drywall screws, it is very easy to attach the board. Before you put the board in place, make sure you mark where the studs are. After the board is hung, you will need to tape the seams with drywall tape. Then, use drywall mud to cover all of the screw holes and tape.

The final step is to texture and paint the wall. You will, of course, want to match the existing texture on the wall. The difficulty of this job wholly depends on what type of texture you have. Spray-on texture is easy to match, but hand-troweled texture requires a little more craft.
