Sanding a wall before painting is essential to create a smooth surface. You can use a sanding block or sandpaper to smooth out the wall’s texture. If there are gaps, you should sand them first to create an even surface before filling them with filler. Sanding the wall for bare walls will make them smoother and help the paint adhere better to the surface.

You can use sanding sponges and 100-grit sandpaper to remove imperfections on the wall. You can also use a pole sander to speed up the process. After sanding the wall, you should wipe it down with a damp cloth and allow it to dry before the next step.

You can also use a joint compound to fill any holes or cracks in the wall surface. Depending on humidity, it is essential to wait at least four to eight hours for the joint compound to dry. You can use sandpaper or painter’s tape to test the joint compound. If the joint compound is too soft, it is not suitable for sanding.

If the walls are in an old house, they may have lead paint, which is a health risk. The sanding process can release lead dust into the air. You can also use a hand pad or standard paint scraper to remove loose paint. The aim is to remove as much paint as possible while ensuring that the wall’s surface is smooth and flat. Take care not to over-scrape.

Preparing the wall is one of the essential steps before you can start painting. It helps prevent bleed-through, cracking, and uneven coverage. It also helps the paint adhere better. The next step is to use a primer. This step is significant if the wall is drywall, as the primer will help the paint stick to the wall.

Before you start painting, make sure the surface is smooth and free of blemishes. The paint will accentuate flaws and imperfections, so it is imperative to repair them before applying primer. It would help if you also sanded the wall before applying paint. Sanding creates dust, so wear safety glasses and work gloves. Using a dust mask is a good idea too.

If you have trim work to paint, you should follow the manufacturer’s instructions when applying the paint. It is also a good idea to caulk any trim work you are painting. This will give the room a finished look. You can also spot sand with a sanding pole to remove dried paint chunks.

Once you have completed the sanding process, you can apply the primer and paint. Remember to wear gloves, and remember to wash your hands afterward.
