What grit sandpaper for painted walls?

If you're planning to paint over an already-painted wall, you'll need to sand it to create a surface to which the new paint can adhere. The best grit sandpaper to use for painted walls is 120 to 150 grit. This grit is fine enough to smooth out any imperfections on the surface without damaging the paint layer. It is also coarse enough to provide a good grip for the new paint.

When using sandpaper to prepare painted walls for repainting, it's important to follow the proper sanding technique. Begin by wiping down the wall with a damp cloth to remove any dust or debris. Then, use a sanding block or sandpaper wrapped around a sanding sponge to gently sand the surface in a circular motion. Avoid applying too much pressure or sanding the same spot for too long, as this can damage the paint layer. Once you've sanded the entire surface, wipe it down with a clean cloth to remove any dust.

In conclusion, the best grit sandpaper to use on painted walls is 120 to 150 grit. This grit level is fine enough to smooth out any imperfections without damaging the paint layer, making it the ideal choice for preparing a painted wall for repainting. By following the proper sanding technique, you can achieve a smooth and even finish that will help your new paint adhere properly.
