Repairing a hole in the drywall can be a very satisfying Do-It-Yourself experience. The equipment required is easily procured and even if you don’t get it right the first time, you won’t be doing any damage to the structure. With the right information and guidance, you can easily repair a drywall. Once acquired, the skill will stand you in good stead as a homeowner.
You need to have the following material ready – drywall, mesh tape, setting compound, backer boards, and drywall screws.
Drywall, also referred to as gypsum board is available in different sizes. The piece of drywall you purchase must be larger than the hole that you wish to cover. Interior walls often have ½” thick drywall. Ensure that the thickness of the drywall you purchase matches that of the existing wall.
Paper tape works best because it offers the strongest joint. It is also a better option because it resists movement and stress on the joint more effectively. Fiberglass mesh tape is another alternative.
Choose setting compound with a longer drying time if you’re new to repairing drywall. Setting compound is a powder that forms a cake when mixed with water. You will also need to purchase backer boards that can secure the new drywall in place.
The necessary tools are easily procured. A drywall saw, drywall knife, sandpaper, drill and a utility knife are all that you need.
Score the edges before you get around to securing the backer board. If the size of the hole is such that it cannot be remedied by filling it with a compound, then you need to screw a backer board in place. Once that is done, you can cut a new piece of drywall that will fit into the gap. Cover the new drywall with tape. Apply one coat of compound. A compound with the right consistency, neither too wet nor too thick, is desirable because it yields the best results and is also easy to work with. See that you eliminate air pockets when you coat the surface. Ensure that the tape, mesh or paper, is totally covered by the compound.
After this first coat dries up, sand it if there are any irregular surfaces. Then apply another coat. The idea behind two or three coats is to create a finish that does not betray any work done. Eliminate gritty edges and rides with the sandpaper.
Use a primer before you paint this patch. The compound will react differently to the paint, and without the primer, you’ll notice differences in color between the repaired patch and the rest of the wall.
