WiseSeal® End-Grain Sealant is a specially formulated water-based sealer to protect fresh cut ends of boards. End cuts of decking and lumber dry out faster than the center, which can lead to unsightly end checks (drying splits) that can spread quickly. These end cuts also expose decking and siding material to the elements which require added protection to prevent water intrusion that can lead to swelling, mold, mildew, warping and cupping.

WiseSeal® is proven to increase the structural integrity of hardwood, thermally modified wood, soft woods, PT (pressure treated) and composite material.

Designed to protect decking, siding/cladding, railings, steps, log ends, turning blanks, and other exposed end grain. DeckWise® makes it easy to protect inventory and on-site material for long-lasting results. WiseSeal® is a durable water-based formula, eco-friendly and forms a flexible, breathable barrier by coating the wood fibers at the cellular level, providing exceptional protection. This product is paintable and stainable after 24 hours.
