Concrete Sealer X-1 is a permanent silicate based deep penetrating sealer which means that it is guaranteed to last for the life of your concrete because it chemically bonds to the concrete to become part of its integral structure. It is highly effective in making concrete physically stronger and denser, protecting it against frost and salt while increasing its resistance to stains, acids, alkalis, moisture, mold and mildew. This sealer will cure damp and wet basements by preventing hydrostatic water from penetrating through the concrete. It will also stop dusting, efflorescence, spalling, pitting, crumbling and prevent mold, mildew and algae growth. The sealer will seal the concrete to significantly reduce the level of radon gas penetration which is known to cause lung cancer by the EPA. Concrete Sealer X-1 can be used in all commercial and residential concrete applications to treat damp or wet concrete basements, concrete floors, concrete walls, concrete driveways and sidewalks, concrete garage floors, concrete warehouse floors, concrete storage tanks, concrete pipes, concrete blocks, grout, mortar and stucco. It can also be used to extend the life of exterior wood including fences, patios, decks, cedar and wood shingles. This sealer is not recommended for decorative, stamped or aggregate concrete. Concrete Sealer X-1 penetrates through the capillaries of the concrete to a maximum depth of up to 4" where it chemically neutralizes damaging chemicals to form a hard insoluble structure based on calcium silicate and calcium hydroxide. Unlike surface coatings this sealer will not be damaged by efflorescence or be worn down by heavy traffic because it is permanent. Stone Technologies Products are Guaranteed!Concrete Sealer X-1 leaves a natural finish (no sheen) after application, it is UV resistant, non-yellowing, breathable and the surface will not be slippery. This sealer is not a repellent coating so the concrete can be painted after it has been sealed with increased paint adhesion because the sealer neutralizes the alkalis in the concrete preventing saponification of the paint. Adhesives and epoxy coatings can also be applied over the sealed concrete with no adverse effects. Concrete Sealer X-1 is environmentally friendly, non-toxic and nonflammable because it does not contain chemical solvents or release any VOC or noxious fumes. Concrete Sealer X-1 is a ready to use, DIY type sealer which has a shelf life of at least two years. This concrete sealer is guaranteed to last for the life of your concrete. After cementitious surfaces have been treated with Concrete Sealer X-1 and Concrete Sealer X-2 they can resist many chemical compounds more effectively including acids, salts, solvents, alcohols and oils. Concrete Sealer X-1 has been tested against the following specifications; NCHRP 244 AASHTO T-277-83 ASTM C 418 Concrete Sealer X-1 is easy to apply using a brush, medium nap roller or low pressure sprayer at any temperature between 40-80°F. The surface to be treated does not need any special treatment but it must be water, oil and dust free to allow proper penetration of the sealer. Check the surface of your concrete before applying this sealer to make sure it absorbs drops of water within 20-30 seconds, If it beads up then use Eco Concrete Etcher prior to applying this sealer. Coverage rate is approximately 200 to 400 sf/gal/app depending on the concrete porosity and two coats are recommended rather than one thick coat. Application time between coats is 2 to 4 hours and allow to cure for 24 to 48 hours without rain.
