Finishing Drywall

The "fuzz" that is associated with sanding drywall is a constant battle between the sanding guys and the painters...who should take care of that fuzz? Our Online store at www.abrasiveresource.com sells 9" discs in both PSA and hook-n-loop that can be used on the power sanders most often used in finishing drywall. The sanders typically use an 80, 100, 120 or 150 grit (depending on the tape job!) and the painters are using a 220 to sand after the prime coat is applied.
Here are some ideas to eliminate the fuzz, suggested by the very people who are dealing with it on a day to day basis. If you have other ideas, please e-mail us here at: mail@abrasiveresource.com,
Finishing Dry Wall
1. Try to keep the sandpaper off the drywall paper and you won't have the fuzz!
2. Take a soft bristle floor broom to the surfaces after the final sanding and prior to the first coat of paint, which removes the particles from the "fuzzed" paper face. This will allow the paint to lay the damaged paper down and flow across the surface more efficiently.
3. Another way to clean the surface and lay the damaged paper down is to wipe the sanded areas with a damp sponge before painting.
4. Use a quality primer.
5. Prime coat should be rolled or sprayed and back-rolled. This lays down the sanding lines and adds a small amount of stipple for good coverage.
6. Check the directions on the paint can. Most are clearly marked "sand between coats".
