SEAL-ONCE® POLY Premium Wood Sealer shields wood from water damage and decay by forming a durable coating on the wood’s surface. The enhanced UV inhibitors and superior abrasion resistance offer the highest level of protection against the elements.

POLY is a single component, water based aliphatic polyurethane that is APEO free. It does not contain mercury, heavy metals or silica. POLY is a non-toxic, low odor formula that can be applied around landscaping, vegetation or water without causing damage.

The long-lasting, ultra-low VOC, water-based polyurethane protects wood from weathering, scuffs and scratches, in addition to preventing wood rot and decay by impeding water intrusion. It also stabilizes the wood, eliminating warping and cupping caused by water intrusion.

The UV inhibitors in our POLY prevent color fading. POLY also prohibits stains caused by mold, mildew, algae and fungi.
