Unique, state-of-the-art waterproofing concrete sealer and concrete stain in one! Waterproofs concrete to protect against water, efflorescence, spalling, salts, and freeze-thaw. Spectacular semi-translucent variegated look, similar to acid staining but many more colors. Penetrates deep into concrete (2″-4″), strengthens and waterproofs. It’s like filling the pores with epoxy! Limited 15-year Waterproofing Warranty. No film, not shiny or slippery. Beautify dull outdoor concrete like concrete driveways, sidewalks, patios, and pool decks. Stain indoor concrete floors like in basements, slab-on-grade floors, hallways, dining rooms, lobbies, offices. You can add a glossy clear coating (acrylic, urethane, epoxy) for luster and protection. Environment-friendly – waterborne, no acids, ultra-low VOCs. No strong odors. Easy application with a pump-up garden sprayer. The concrete must be clean, thoroughly dry, and POROUS! The surface should absorb water, not bead. If the surface is too tight, the stain pigments will not penetrate and easily wash off, e.g. hard-troweled concrete, stamped, burnished or polished concrete, fibercrete, previously sealed or painted concrete. New concrete is too caustic – the pH must be below 9 but above 6. We recommend the safe approach – always ACID-ETCH OR SAND the concrete first. After etching, neutralize the surface with baking soda, ammonia, or an alkaline cleaner. Test the stain first in an inconspicuous area, let it cure for three days and try to rub it off with a wet rag – the stain should not come off. Do not over-apply! One application in a thin glistening film is usually enough. A light second application can be applied later, provided it absorbs. THE CONCRETE PREP AND THE APPLICATION ARE THE RESPONSIBILITY OF THE USER. WE CANNOT GUARANTEE THAT THE STAIN WILL PENETRATE. Shipped in two-packs with two 2.5-gall containers. Coverage per 5 gallons … 1,000-1,150 sq. ft. on indoor poured concrete, 750-1,000 sq. ft. on outdoor poured concrete.
