DECK-O-SHIELD is a ready-to-use sealer/water repellant for natural stone, concrete and masonry surfaces. It is designed for use as a sealer/water repellent on waterfalls in or around swimming pools; the product will limit the penetration of water into structurally sound, crack-free surfaces. The product also can be used for natural stone decks, walkways, or patios; virtually any area located near or around swimming pool areas. A DECK-O-SHIELD-treated surface will inhibit the penetration of salts into the surface, reducing "whitening" or staining. It weatherproofs and protects virtually all waterfalls, decks, porches, patios, and walkways around pools, including mortar joint, concrete, brick, concrete block and stucco.  For more information, call 800-542-POOL or visit www.deckoseal.com.
