When you notice that your drywall needs patching up, it sometimes takes more than a putty knife and some spackling to get the job done correctly. Patching up your drywall is especially important when you want to paint it so you can get the results you are looking for. To avoid any problems along the way, here are a few tips on how to properly patch up your drywall.
Before you start patching and painting your drywall, you will need to prime the spot with a sealing type primer. This is an important step because the patched areas could show through as foggy spots when you are done painting the wall.
Fill bigger holes with a setting compound
If you notice that there are holes in your drywall that are larger than a dime, than you will need to use a joint compound. You should be able to find one in powder form that uses chemical reactions to set within 90 minutes. You can find compounds that set in five minutes when it’s mixed with water, which means you can apply more coats quicker if the job calls for it. Be aware that setting compounds are difficult to sand, so make sure you apply it straight on the surface to fill the hole in your drywall.
Create a dent for your patching compound
When you take out a picture hanger or nail from drywall, you are usually faced with a hole with a small amount of drywall sticking out, which can be hard to cover up. What you need to do is make a dent over the hole, then fill it with your patching material. If you have a good putty knife that features a hard plastic handle, you can use that to make a perfect size dent to fill. You can also use the end of a screwdriver handle to get the same results. If you are confident in yourself, you can use the end of your tool like a hammer to make the dent or you can just apply pressure with your tool to the hole while twisting.
Fix multiple holes with a skim coat
If you have an area in your home where you store all of your golf clubs and hockey sticks and they leave a lot of small dents in your walls, you will go crazy trying to fix each one individually. What you will want to do is use an all-purpose joint compound, then use a wider taping knife to apply the compound when the holes are located.
You can use the same technique if you are renovating a wall that had a lot of pictures in a straight row on it. It makes it easier to sand the entire line of compound, rather than sanding each individual dent you make if you tried to repair each hole one at a time.
Fixing peeled drywall
If you have torn off the top layer of your drywall paper trying to replace an adhesive picture hanger, you will need to fix it with an oil or shellac based sealer. Once the sealer has dried, you can sand it lightly to remove any hardened paper fuzz, then patch it with the same compound as you would normally use.
