Which roller nap length is best suited for a smooth surface such as new drywall or a fine finish?
a.1 inch nap
b.A short nap (about 1/4 inch)
c.1-1/4 inch nap
d.No nap is ever used on drywall
Giải thích
Short-nap rollers (around 1/4 inch) hold less paint and lay down a smooth, fine finish suited to smooth walls, doors, and trim. Longer naps are for textured or rough surfaces because they reach into the profile. Matching nap length to surface texture controls stipple and coverage.
