DO focus on bumpiest areas.
Start off with wide gentle strokes to soften the entire stretch of drywall mud, and then focus on the uneven or ridged areas, using circular motions to smudge out the imperfections. Let the sponge and the water do the work—not the strength of your hand. Aim to smooth away imperfections without creating valleys or holes.
Sanding drywall releases very fine particles of dust into the air. Inhaling the dust can irritate the lungs and eyes. The dust can also settle on unprotected clothing and furniture. Before taking on a small- or large-scale drywall sanding task, follow these tips:
Wet sanding with a sponge is ideal for small patches and tight corners since it’s easier to work a sanding sponge into those areas.
Hand sanders and pole sanders use sanding screens fitted with sandpaper. Apply a push-pull motion when using a hand sander or pole sander, applying even pressure inside the seams and along nail and screw patterns. Use semi-coarse sandpaper of 100 of 120 grit to sand down the rough areas or dried compound, then continue with 150 grit to smooth the areas further.
Use fine grit sandpaper, between 150 and 180 grit, to achieve the desired results. Some drywall sanders include a vacuum attachment to collect excess dust and debris. Follow the manufacturer instructions supplied with your unit for directions on assembly.
Wet sanding also creates less dust, making it easier to clean up after the job is done. However, this method tends to result in finish that is less smooth than dry sanding.
Choose drywall and try wet sanding to reduce the dust
