Before applying, it is strongly recommended that you pre-treat the base surface, using any standard water-based acrylic primer. Also, use mesh on joint seams to prevent cracks. *Chip board, particle boards of any type, luan, OSB, and tounge and groove planking are unsuitable. We recommend covering the wood with exterior sheet material.
