When it comes to repainting a surface, one of the most important steps is preparing the surface by sanding it down. This is done to remove any old paint or imperfections on the surface, ensuring that the new paint adheres well and looks smooth. But what grit sandpaper should you use for paint? In this article, we'll explore the different grits of sandpaper available and help you determine the best grit for your painting project.
What is Grit?
Before we dive into what grit sandpaper is best for paint, let's first understand what "grit" means. Grit refers to the roughness of the sandpaper's abrasive surface. The higher the grit number, the finer the abrasive surface is. Lower grit numbers mean a coarser abrasive surface that is better suited for heavy sanding tasks.
Types of Sandpaper Grits
When it comes to sandpaper, there are many different grits available, ranging from very coarse to very fine. The most common grits available include:
- 60 to 80 grit: These are coarse grits that are best used for heavy sanding tasks, such as removing old paint or rust from metal surfaces.
- 100 to 150 grit: These grits are considered medium and are ideal for preparing surfaces for painting or removing small imperfections.
- 180 to 220 grit: These grits are fine and are best used for sanding between coats of paint or removing light scratches.
- 320 to 400 grit: These are very fine grits that are used for finishing and smoothing surfaces.

When it comes to sanding paint, you'll want to use a fine grit sandpaper in the range of 180 to 220. This grit is ideal for sanding between coats of paint to remove any imperfections, bumps, or drips. It's also good for removing light scratches on painted surfaces without damaging the paint.
If you need to remove old paint or rough up the surface for better paint adhesion, you'll want to start with a coarser grit of 60 to 80. Once you've removed the old paint or roughed up the surface, switch to a finer grit of 180 to 220 for final sanding before painting.
In conclusion, when it comes to sanding for painting, it's essential to choose the right grit of sandpaper to ensure the surface is properly prepared for painting. A fine grit sandpaper in the range of 180 to 220 is best for sanding between coats of paint, removing imperfections, and scratches. For rougher surfaces, start with a coarser grit of 60 to 80 before switching to a finer grit for final sanding.
