Transform your home with the old-world European appeal of this Nube Gray Limewash Interior/Exterior Paint by Romabio Classico Limewash. Specially designed to produce a unique effect on unpainted brick, stone or other masonry surfaces, this interior/exterior slaked-lime paint is simple to apply and will last for years. You don’t need primer, and the breathable formula is non-toxic and UV resistant. After covering your selected damp surface with one coat, wash it off with a garden hose or spray bottle. This will produce that antique lime wash finish for a historic effect. This paint hardens over the years without peeling or chipping off. One coat covers 450 sq. ft. per gallon.
