what nap roller for walls

The best nap roller for walls depends on the texture of the surface. For smooth surfaces such as new drywall, a shorter nap of 3/16" or 1/4" is recommended to apply the paint evenly and maintain a smooth finish. For walls, wood, and metal, small 1/4" nap roller covers or foam rollers will produce the smoothest finish. For lightly textured walls, decks, and concrete, a 1/2" nap is recommended, while walls, ceilings, and paneling require a slightly larger nap size of 3/8". Microfiber rollers are best for light to medium textured surfaces, while a white woven short nap roller is recommended for an ultra-fine finish on smooth surfaces. If a thick 3/4" nap roller cover is used on a smooth wall, it can produce an orange peel textured surface. In summary, the nap roller size for walls depends on the texture of the surface, and it is recommended to use a shorter nap for smooth surfaces and a larger nap for textured surfaces.
