  • Brazilian Rosewood Oil: Strong, flexible, water-resistant oil sustainably harvested from the nuts of the Brazilian rosewood tree. Allows the wood to retain its flexibility. Creates no surface film. No trees are ever cut down to obtain this oil.
  • Transoxide Pigments: These pigments also penetrate into the wood protecting it from the inside out from the sun’s damaging rays. Penofin provides up to 99% ultraviolet protection. It adds a rich, transparent color to enhance the natural beauty of the wood, highlighting the grain.
  • High-Grade Mildewcide: The finest possible mildewcide is used to retard growth of mold and mildew.
  • Penetration: Penofin’s low-solid formula ensures easy application; there are no lapmarks as with high-solid formulas. A high-solid stain means you must keep a wet edge during application or you will end up with an uneven finish. This simply does not happen with Penofin.
