Proper Drywall Patching Techniques

By Brian Winters


Compared to plastering, patching drywall holes is easier since they don't require a lot of time to fully dry out. Though drywall is not the most durable material in covering walls and ceilings, it shouldn't be a problem as long as you know how to patch drywall and secure them to the joists.

Tools and materials needed:

-Steel square

-Utility knife

-Drywall saw

-Wide blade taping knives

-Scrap wood

-Drywall screws or nails

-Fiberglass mesh tape

-Joint compound

-Drywall sandpaper

Using the steel square, measure and outline the damaged area, extending an inch or so on all sides around the hole. Make sure the sides have studs behind it to support the panel securely. This is important since working with an irregularly-shaped hole can take a lot of time.

Reach inside the hole if there are any obstructions behind the panel. To remove the damaged area, use a utility knife to run it over the lines. You may have to repeat this step until the drywall is completely detached. Do not forget to remove the torn paper edges before you proceed.

To provide added support, attach the scrap wood longer than the opening. When drilling the screws, do not forget to countersink them to avoid having nail heads above the surface. You may end up applying multiple layers of mud if you don't countersink the nails.

Fit the drywall panel inside the hole and screw each side to the joists and back framing. Avoid causing your drywall to crumble by attaching nails far from the edges. Again, make sure the nail heads are below the surface.

You can now tape the seams to seal the gap in between. Use a fiberglass mesh tape and press it evenly to prevent it from bubbling up. Cover the tape pieces with spackling compound and feather it out on the edges. Let it dry before covering the entire panel. Use a sanding block to remove the bumps and beads once the surface has dried all throughout. Prime and paint.

Simple isn't it? Knowing how to patch should be easy as long as you're willing to get your hands dirty. However, feel free to contact a specialist for professional help.
