Which roller nap length is best suited for a smooth surface such as new drywall or a fine finish?

1. A1 inch nap
2. BA short nap (about 1/4 inch)Đúng
3. C1-1/4 inch nap
4. DNo nap is ever used on drywall

Vì sao: 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.

Under the EPA Renovation, Repair and Painting (RRP) Rule, work that disturbs painted surfaces in housing built before which year generally triggers lead-safe requirements?

1. A1998
2. B1978Đúng
3. C1985
4. D1960

Vì sao: The RRP Rule applies to housing and child-occupied facilities built before 1978, the year lead-based paint was banned for residential use in the U.S. Firms disturbing more than the de minimis area of paint in these buildings must be certified and use lead-safe work practices. This protects occupants, especially children, from lead dust.EPA RRP Rule
