Yes, all NextStone products can be recoated but because of the "mold release agent" on the outer surface of the products, each piece must be prepared accordingly. The surface must be wiped down with a soft bristle brush or clean cloth. Paint primer is not required, but if you choose to use a primer it must be compatible with polyurethane products. In addition, we recommend using Sherwin Williams Flat Latex A100 Water-based paint.
