Learning More About Drywall Repair

Drywall is also known as plasterboard or wallboard. It is commonly used in construction for wrapping columns, concealing beams, and topping off ceilings. It also serves as protection from fire. Most home and building contractors recommend drywall installation for added protection.
Damaged drywall is such an inconvenience. The repair can be quite expensive. It also decreases the value of the house.
Common Causes of Drywall Damage

• Plumbing Leaks
This is one of the leading causes of broken drywall. If the plumbing is old or it was not properly installed, major problems may arise.
The leaking water weakens the hold of the drywall. It causes the wall to bulge and eventually breaks. If you notice water marks or if the wall is bulging, it is best to inspect and repair the waterline. Then replace or patch up the damaged drywall.
• Popping Nails
If nails were not securely set during installation, a nail may pop through the drywall after some time. Don’t immediately use a hammer to put the nail back in place to avoid further damage to the wall. Find the stud first before hammering the nail back.
• The Drywall Is Not Fastened Well
In drywall installation, a joint fastening tape is used. The thick tape may come loose due to moisture and the damage will be quite noticeable.
• Loose tape
The tape may break lose and create bubbles, eventually, it might come off. Use a knife to cut around the bubbles. Uninstall the tape. Then apply joint compound to the hole. Install a new strip of tape and cover with a thin layer of joint compound.
• Cracking
This is caused by improper installation of the drywall. This often occurs in ceilings. Cracked drywall is a safety issue and can also be caused by the house settling.
Cracks may also form on the ceiling when there is moisture or water leak. If you notice cracks on your ceiling, it is important to inspect your roof and/or check the plumbing inside the house. Don’t ignore cracks on walls and ceilings because small cracks may become bigger, and you’ll have more problems.
• Termite Damage
Termites feed on dead plants and wood fibre. They are a major issue for many homeowners.
Call an exterminator immediately if you notice signs of termite infestation. Signs of termite damage include pinholes and a hollow sound when you strike the wall. Damaged wood and paint job are also signs of termite infestation.
• Holes
Any type of hole in the wall is considered a structural issue. It can be caused by furniture bumping too hard against the wall, doors banging, or kids’ toys thrown on the wall.
If you notice a hole or holes on the drywall, repair it as soon as possible. This will prevent it from further cracking that can lead to a whole wall replacement.

2. Cut an angle where the exterior of the hole becomes larger than the interior.
3. Apply painter’s putty into the wall. Make sure that it is in level with the surface of the wall.
4. Make sure the area is completely dry before applying sandpaper to smoothen the area.
For medium holes:
1. Sand the surface around the hole and wipe off the dust.
2. Use a drywall metal patch. Press the patch to secure its position, with the mesh facing outward.
3. Spread the drywall compound over the patch. Smoothen it out and let it dry. Repeat application of drywall compound until patch is no longer that obvious.
4. Gently sand the surface until smooth like the wall.
For large holes:
Larger holes need patches that are made of drywall. It should be the same thickness as the drywall already present.
1. Cut out a square shape from the drywall patch. The size of the square should be slightly larger than the hole.
2. Using a pencil, draw a square outline around the hole.
3. Check for plumbing lines or electrical cords around the area before cutting with a drywall saw.
4. Mount two wooden boards behind the drywall. Position them one on top of the other. This will secure the patch on the wall.
5. Screw-in the patch to the boards.
6. Spread the drywall compound, making sure the whole area is covered. Add a mesh. Repeat this step until you no longer see the drywall patch.
7. Sand until the area is smooth enough, without a trace of the patch.
8. Let the area to completely dry before applying paint.
Plaster is often used for coating walls, ceilings and partitions. The common causes of plaster damage include:
o Settling of the house
o An occasional earthquake can cause plaster to crack
o Water damage from roof or plumbing leaks
o Expansion and contraction of the house’s wood framing
Plaster Repair
1. Scrape the damaged areas
Prepare the area by removing any flaking or loose plaster. Chip away the damaged plaster with a cold chisel and a ball pen hammer. Scrape away any excess debris.
Make sure not to hit too hard. This could damage the wood latch behind the plaster.
2. Mix New Plaster
Mix enough amount of plaster needed. Continue mixing until you get a consistency similar to a cake frosting.
3. Apply the Plaster to the Damaged Area
Use a 10-inch wallboard knife to spread the plaster mixture. Spread a ¼ inch layer over the hole. It is best to cross-scratch the first coat. This allows the second coat to adhere well.
Apply the second coat and cross scratch.
4. Apply a joint compound
Mix a joint compound. Apply a thin layer over the dried second coat of plaster.
5. Sand and Paint
Sand the fixed area with a sandpaper block. This makes the surface smooth and ready before applying paint.
