Step 2 · Sand the Stair Treads (Optional)

If you are using a liquid or spray-on anti-slip coating, a light sanding can improve adhesion. Use a fine-grit sandpaper (180-220 grit) and gently scuff the surface of each tread. The goal is not to remove the finish, but to create a slightly rougher texture. After sanding, vacuum thoroughly again to remove all sanding dust.
