Drywall Sanding Guides

Drywall sanding is the opposite of floor sanding — you are smoothing joint compound, not removing wood. The grits are finer, the pressure is lighter, and the goal is a surface so flat that paint reveals no ridges, bubbles, or tape lines. Get it wrong and every imperfection telegraphs through your finish coat.

These guides cover grit selection for new construction and repair, pole sander technique, dust control strategies, and the most common mistakes that force a second skim coat. Whether you are finishing a full room or patching a single joint, the right sandpaper and the right method make the difference between a wall that looks professionally finished and one that looks like a DIY project.

Start below with our drywall finishing guide for complete grit recommendations and technique.
