Rosie on the House: Repairing, patching damaged drywall | Get Out
Regardless of the age of your home, drywall damage will occur. Minor damage is relatively easy to repair. Small screw or nail holes can be patched with white toothpaste and touch-painted to fade in.
Repairs to areas with major water damage are best left to professionals. You never know what kind of damage is lurking behind that drywall, such as: B. Mold that should be left to a professional mold remediation expert.
The age and condition of the paint on your wall, as well as the paint stored from the time it was applied, are key factors in how quickly you complete drywall repair projects. The quality of the patchworks is critical to restoring drywall to look like new. The paint looks only as good as the surface it was applied to. A bad stain with a poor texture match will stand out more than expected, even the best paint finish.
• Utility knife or drywall saw
• Straight 12 inch edge
• Coarse sponge or sandpaper
• Acrylic sealant if the patch is matched to a countertop, shower, tile surface, etc.
• Drywall tray for large amounts of mud
• Texture spray for orange peel surfaces
Water-damaged drywall can be identified by waves or bubbles in the paint. If you feel the bubbles and they are not firm, or if the paint peeled off as soon as you touch them, there is likely a water problem.
Other common signs are areas where drywall is soft to the touch and water spots / discoloration appear. Before starting any repair of water-damaged drywall, you need to identify and fix the source of the water ingress.
If water gets into your wall from rain, a sprinkler system too close to your house, or even a leak in the plumbing, you can likely see damage to your walls near where the leak occurs . That’s because drywall has a paper backing. When they get wet, they can bubble and wrinkle, much like a piece of paper.
To diagnose the problem, place a 4 foot level above the damaged area and learn how much the sheetrock has sagged. If it’s more than 3/8 of an inch, the structural integrity of the drywall is likely ruined and the section should be replaced.
If there was no sagging, use an awl to randomly press into the sheetrock. You should feel significant resistance, and the awl should not be able to penetrate the sheetrock more than 1/8 of an inch without undue force. However, if the awl goes through the sheetrock much deeper than 3/16 of an inch, consider replacing the section.
Replace the section: Use a utility knife to cut out the damaged area, leaving a square or rectangle so you can easily combine it with a new piece of drywall. Look in the hole to see if the damage goes deeper than the drywall (such as the studs) and find the cause of the leak so you can stop it before repairing the wall. Put a fan near the hole and dry the area thoroughly before proceeding. Cut a new piece of drywall so it fits snugly in the new hole. You may need to secure it with a piece of plywood. Attach the drywall and cover the seams with a good quality drywall tape.
Prime, paint and watch closely if the damage returns. This could indicate a more serious water problem than you suspected.
Repair the damage: If the damage is superficial, you may not need to replace the drywall. Dry the area thoroughly, sand the blisters, and prime the area with a pigmented paint product called KILZ, which will prevent the stain from bleeding through the new coat of paint.
