How to Remove the Top Layer of Paint With Sandpaper Grit

Use sandpaper to remove layers paint.

Sanding old paint is probably the least enjoyable part of a painting project. Sanding takes time and a careful touch to avoid permanently damaging the surface underneath. Removing the top layer of paint is tedious, but crucial to achieving a strong bond and a long-lasting finish for the new coat of paint. Thorough sanding is required for nearly every type of painting project.

Things You'll Need

• Dust mask
• Respirator
• Water
• 80-grit sandpaper
• Rag
• Putty knife

Instructions

1. Tightly secure a dust mask or respirator over your face. Inhalation of sanding dust can lead to health problems and even poisoning if the paint contains lead.

2. Run warm water over a folded piece of 80-grit sandpaper or a sanding sponge. The water loosens old paint during sanding and speeds up the removal process. Water also reduces airborne dust particles.

3. Rub the folded sheet of sandpaper back and forth in the direction of the wood grain, not against it. Rubbing against the wood grain results in noticeable scratches, unless you're sanding a metal surface. Use an electric power sander for large jobs.

4. Wipe old paint and sanding debris from the surface using a rag to reveal the results. Use a putty knife to remove stubborn paint build-up. Continue sanding to completely remove the top layer of paint. Lightly scuff the bare surface with sandpaper and avoid over-sanding after removing the top layer of paint.

Tips & Warnings

• Buy several sheets of sandpaper. Sandpaper wears quickly and you may need several sheets to finish the job.

• Do not sand paint without wearing a dust mask or respirator.
