Paint Roller Nap Guide: 1/4" vs 3/8" vs 1/2" vs 3/4" Sleeve Thickness
Roller nap thickness determines paint holding capacity and surface texture transfer: use a 1/4-inch nap for ultra-smooth surfaces like cabinet doors and metal trim; use a 3/8-inch nap for standard smooth interior drywall walls and ceilings; use a 1/2-inch nap for textured drywall (orange peel, knockdown) and exterior smooth siding; and use a 3/4-inch to 1-inch nap for rough masonry, brick, stucco, and acoustic popcorn ceilings.
