SEAL-KRETE® DRY-LOOK Penetrating Concrete Sealer uses Silane-Siloxane technology that bonds with concrete to form a watertight seal. It provides long-lasting protection with no visible appearance for porous, uncoated, horizontal and vertical surfaces. Dry-Look is recommended for use on concrete driveways, exposed aggregate, brick, pavers, slate, sandstone, concrete block and unglazed tile.
