Wet and Dry Sanding Guidance
For dry sanding, use appropriate dust-control practices and personal protective equipment. When wet sanding, keep the work surface and abrasive sponge adequately damp to help reduce airborne dust and clear away sanding residue.
Always test the abrasive on a small, inconspicuous area first. Use controlled pressure and avoid excessive sanding on thin edges, sharp corners, delicate coatings, and exposed substrates.
