Flat enamel is a paint with a durable flat, matte finish. It's a good choice for powder rooms and halls, as it holds up to occasional cleaning. Where to Use • Interior: Walls, ceilings, woodwork; bedrooms, family rooms, dining rooms, kids rooms and offices. Surfaces: Wood, drywall, aluminum, masonry, brick, stucco and vinyl. Cleanability and Durabilityiu A general rule is that the shinier the paint finish, the better it will stand up to washing and cleaning. For best results; use Diamond-Brite PVA Primer-Sealer to properly prepare and seal the surface before painting.
