PenaShield 1 gal. Borate Wood Treatment and Preservative (4-pack)

PenaShield is a ready-to-use formula that can be sprayed or brushed on raw wood. It is a unique patented preservative that penetrates the wood, delivering long-lasting protection. PenaShield will not stain or discolor wood; and once dry, can be painted or treated with a water sealer, stained or varnished like normal wood. The active ingredient in PenaShield is a borate mineral salt which sets PenaShield apart from competitors in that the mineral salt will not break down over time like other synthetic chemicals. You must maintain a water repellent treatment to preserve PenaShield coating. PenaShield will last for the life of the wood if you maintain a sealer treatment. Whenever you're working with wood, whether it's projects or repairs, always use PenaShield to protect the wood.
