Repairing Damaged Drywall
Sanding drywall can be messy, aggravating, and even hazardous. A respirator and protective glasses are among the drywall supplies you will need for sanding. If done correctly, you can expect a great-looking paint job that will make all of your efforts worthwhile.
To help you get the job done correctly, here are some guidelines for sanding drywall:
- You’re going to need the right tools. In addition to the safety products, you’ll need a hand sander, 150-grit sanding paper, and a sponge. It might also help to wear a hat or scarf to keep the dust out of your hair. For a large sanding job, pole sanders are helpful. However, only use one if you’re confident that you can handle it correctly. When using a sanding pole, keep the head angled slightly. Avoid getting the head at a right angle to the pole, as doing so can cause the tool to flip over and mar the surface.
- When using the sander, sand with light pressure around screws and along the edges of seams. When there are bumps and ridges, sand the center of the seams.
- Control the dust so that it does not get on everything. Not only should you protect yourself, but you should protect everything around you. The dust can drift through the building, forming a white film on the walls, furniture, floor, etc. Consider investing in a dust-catching sanding system, like a screen. This will allow the dust to fall down instead of collecting on the sandpaper. The downside to a screen is that it makes it harder to achieve a smooth finish. At the very least, try to cover as much of the area as possible with plastic drop cloths. You’ll especially want to use these cloths to cover the ventilation ducts and doors
- Practice good techniques when sanding drywall. The mud should be thoroughly dried before you even begin the sanding process. Sand lightly, using light to moderate pressure. Don’t sand in a straight line, as it may show up as a depression when the drywall is being painted. You should move the sander around in a circular motion.
- A sanding sponge should be on your list of drywall supplies. It should be used for sanding corners. Trying to use the hand sander on the inside corners is something you don’t want to do, as you could accidentally gouge or scuff the opposite side of the corner with the edge of the hand sanding tool.
- Be careful not to over-sand. It is possible to sand too much. Even though a hand sander is a straightforward tool, it’s still possible to over-sand if you’re not careful. You also want to avoid sanding over openings - especially electrical boxes. The edges of the box can rip the sandpaper. It’s always best to keep sanders a few inches away from openings. Just touch the surrounding areas up later with a sponge.
- When priming, sand the walls lightly after the primer coat dries to remove paper lumps and fuzz. This is a very important step that many amateurs skip. You don’t want fuzz or lumps showing through the paint job.
You can consult with a drywall company that will help you every step of the project. Good luck with the sanding!
