Drywall repair is a simple process that just about any homeowner can learn to do. Given that homes today are built with lumber inferior to that of generations past, movement of drywall from warping and shrinking in the home’s framing causes a variety of problems related to drywalls. Therefore, many homeowners will need to repair corners, cracks, taped seams, and other drywall imperfections that ensue over time. Also, damage from water intrusion, household accidents and normal wear and tear need a periodic drywall repair to keep the walls looking good, especially before they are painted.
Drywall Repair Tools and Materials
The right tools can make all the difference when repairing drywall. Go to your local home improvement store and buy:
- 4” Drywall Knife
- 12” Stainless Steel Mud Pan
- All-Purpose Joint Compound
- Drywall Sanding Sponge
- Latex-Based Drywall Primer
- 2” Angle-Tipped Paint Brush
- Depending on the amount of drywall repairs required, remove an appropriate amount of joint compound or mud from the plastic tub using your 4” drywall knife and scrape it off into your 12” mud pan. The idea here is to keep the joint compound fresh, so that is doesn’t dry out. So only take as much mud out as you can use within 10 minutes. Otherwise, “chunks” of drywall mud develop, making your drywall repair much more difficult.
- Briefly work the drywall mud back and forth in your pan a few times like you would knead bread dough. This removes air from the mud to help reduce bubbles when you place it on the wall.
- Apply a thin coat of drywall mud to the crack or dent. Use the knife to scrape the mud flush with the surrounding surface of the drywall. It is better to apply 2 or 3 thin coats of mud (allowing each coat to dry in between applications) versus one thick coat. One of the more common mistakes I see with drywall repair is mud that is applied too thick. This rarely results in a good surface and makes for additional time and mess during the sanding phase.
- Allow the mud to dry. Dry time is highly influenced by type and brand of compound, thickness and amount of mud application, as well as ambient temperature and humidity of the room. If you want to accelerate dry time, grab a hairdryer to dry the are
- Once the drywall mud is completely dry, place a drop cloth below the area of drywall repair. Use your sanding sponge to sand the area flush with the remaining wall. Use lighter pressure as you finish to avoid gouging or scratching up your work.
- Take a damp paper towel or cloth to wipe down the drywall repair to remove any remaining dust. You can also use a wet cloth or sponge to wet-sand the area to get an extra smooth effect if desired.
- Using your small paintbrush, apply a light coat of primer to the drywall repair. This will seal the joint compound, hide the repaired area, and prepare it for painting. Apply a high-quality acrylic latex paint.
- When painting the drywall repair, I recommend painting an entire section of the wall, if possible. Although you may have leftover paint from when the wall was painted initially, or purchased new paint with the same formula as the original, it is unlikely to match. Walls age and collect dirt as time passes, altering their appearance and colour.
There are a lot of benefits of having drywall construction in your home. Drywall is simple to mount; it is economical and has fire-resistant qualities. The main thing is this type of wall can be painted, wallpapered and textured too, as well as it is easy to repair.
