Abstract
A water-based wax-free stable emulsion composition, useful as water sealer for wood, concrete and porous materials is disclosed. The water-based sealer composition forms a non-drying film that is water-repellant, flexible, self-sealing and allows passage of water vapor. The water-based sealer composition contains less than 400 grams per liter of volatile organic compounds. The water-based sealer composition is especially suited for above-grade applications in that it protects against absorption of water.
