Wood Protection

Seal Saint Louis wood sealant creates a permanent, effective seal against moisture, acids, molds and more while strengthening decks, fences, and other wood surfaces. It protects without staining or discoloring, so your chosen stain or paint color can shine through. Whether your deck is new or previously untreated, Seal St. Louis wood sealant can add years to its life.

Seal St. Louis wood sealant is not a topical surface sealant!

It was developed to permanently seal, waterproof & harden wood products. The 30 year sealant is very effective against mold, acids, moisture and actually strengthens the wood. In addition to the protective properties, the wood sealant provides a prepared surface 300% more effective in the bonding or varnish, stains, paint & mastics.
