If you're planning to paint your walls, it's important to prepare them properly. One crucial step is sanding the walls to ensure the paint adheres well and looks smooth. But what grit sandpaper should you use before painting walls? Let's find out.
What Grit Sandpaper To Use Before Painting Walls?
Before painting walls, you should use medium-grit sandpaper, typically between 120 and 150 grit. This type of sandpaper is ideal for removing small imperfections, such as bumps or ridges, and for creating a slightly rough surface that will allow the paint to adhere better.
Using finer grit sandpaper, such as 220 grit or higher, may make the surface too smooth for the paint to adhere properly, while coarser grit sandpaper, such as 80 or 100 grit, may leave deep scratches that will show through the paint.
How to Sand Walls Before Painting
Now that you know what grit sandpaper to use before painting walls, here are some steps to follow when sanding:
1. Prepare the room: Remove any furniture, decorations, or electrical covers from the walls. Cover the floors and any remaining furniture with drop cloths or plastic sheeting to protect them from dust and debris.
2. Inspect the walls: Look for any cracks, holes, or other imperfections on the walls. If there are any large holes or cracks, use spackle or joint compound to fill them in and let them dry completely.
3. Sand the walls: Using medium grit sandpaper, sand the walls in a circular motion, starting at the top of the wall and working your way down. Be sure to apply even pressure and avoid rubbing too hard, which can damage the drywall.
4. Clean the walls: After sanding, use a soft cloth or vacuum to remove any dust or debris from the walls.
5. Prime the walls: To ensure the paint adheres properly and looks even, it's important to prime the walls before painting. Use a high-quality wall primer and apply it evenly with a paint roller or brush.
By following these steps, you can ensure that your walls are properly sanded and prepared for painting.
When it comes to what grit sandpaper to use before painting walls, medium grit sandpaper between 120 and 150 grit is your best bet. By properly sanding your walls before painting, you can ensure that your paint job looks smooth and even and that the paint adheres well to the surface.
