While drywall is known to be a fairly resilient surface, it is not uncommon to need to patch a hole from time to time. Perhaps you moved a wall hook from where a picture once hung or you accidently bumped the wall when moving in a new appliance. It’s a simple fix. Whether the holes are large or small, these patches are an easy, smooth repair that will have you wondering where the holes were when you are finished.
 

1

Preparing  Surface

Make sure the surface to be repaired is clean and smooth, and trim away any frayed drywall edges from the hole. Start smoothing the surface by sanding with 100 grit sandpaper, 120 grit drywall sanding screen or a Medium grit sanding sponge. We recommend using an Extra Large Sanding Sponge. This oversized sponge is made for ease of sanding large drywall surfaces. Remember, any imperfection not addressed before the patching and painting process will be very visible after!

Safety Considerations

Since the process of sanding involves the removal of material, it creates airborne dust. We recommend safety glasses, work gloves, and an approved dust mask.

Apply Mesh Reinforcement Tape

When it comes to minor drywall repairs, few products are more versatile and easier to use than adhesive-backed mesh reinforcement tape. 
To start, cut a piece of the tape and apply over the hole so the mesh extends beyond the hole by 1" around the entire circumference of the hole. Apply a second layer of mesh tape at a 45° angle to the first layer of tape and press firmly.

Apply Joint Compound 

Apply a smooth layer of joint compound using a drywall knife or compound spreader. Hold the knife/spreader at a 45° angle to the surface pulling the compound over the reinforcement tape. Be sure to spread enough joint compound to adequately cover the mesh reinforcement tape and fill in the void of the hole behind the tape. Taper the joint compound past the edge of the mesh reinforcement by 2-3 inches. Try to leave smooth edges on the outside rim of the joint compound, as it will be easier to sand later.

Let the joint compound dry for 4-8 hours depending on temperature and humidity. To determine if the joint compound is thoroughly dry, run a piece of sandpaper over the joint compound. If the surface balls up and is soft to the touch, it is not ready to be sanded.

Sand Joint Compound

Once the surface is thoroughly dry, carefully sand the surface by hand using an 80 or 100 grit sandpaper, 120 grit sanding screen, or a medium grit sanding sponge.

When hand sanding large flat areas, you may also want to use a rubber sanding block to support the sandpaper to make sure the sanding surface is completely flat. Be careful not to press into the hole but to sand in even strokes across the area to avoid pushing into the damaged area.

6

Apply Second Coat of Joint Compound

Apply a second coat of joint compound in the same fashion as the first coat/step 4 over the sanded area. This coat should go on smoother than the first coat. Again, wait 4 - 8 hours for the joint compound to dry.

Sand Second Coat

Once thoroughly dry, use a 100 or 120 grit sandpaper, 150 or 220 grit sand screen or Fine sanding sponge to smooth out the joint compound. Pay special attention to properly sand and smooth the outer edge of the joint compound so that it blends with the existing wall.

8

Clean Surface

Using a clean cloth or microfiber wipe, remove any dust left from sanding. It is important to let the wall dry after cleaning if any amount of water is used, otherwise you may find the moisture may get trapped by the paint and cause bubbling or other problems later. Once surface is clean and dry, you are ready to repaint or recover the original surface to match the rest of the wall.
