Can I Sponge Off You?

This technique is useful when drywall filler or spackle has to be made smooth and even with the surrounding surfaces, but sanding would create unwanted dust.

A damp, firm, flat sponge can be used in-place of sandpaper to obtain satisfactory surface readiness for painting without creating a lot of dust. Rub the sponge against the surface with a slow and steady pressure, occassionally emptying the little bit of excess dust from the sponge.
