Sun-Proof® Alkyd/Oil Solid Color Stain is formulated to provide a rich, opaque color that hides the wood grain while allowing the wood's texture to show through. Recommended for use on exterior wood siding, fences, trim, shakes and shingles. Do not use on horizontal surfaces, such as decks. May be used on new wood, pressure-treated wood, and weathered wood. Sun-Proof® Alkyd/Oil Solid Color Stain may be applied as a single coat for economy, or in a two coat system for extended performance.
