DCI Penetrating Lithium Based Sealer Hardener is a clear, odorless, VOC compliant, water-based, matte finish concrete sealer, salt protectant and dust proofer that hardens, seals and densifies concrete. It provides all the protection of a high-end penetrating water repellant sealer and offers all the benefits of a surface hardener, sealer, and densifier. This product penetrates and seals by reacting chemically with the concrete surface forming a clear, dense and durable inorganic topical surface layer that is breathable, abrasion-resistant, and hydrophobic. This matte finish concrete sealer provides no surface gloss and must be scoured using a red and black scouring pad on a high speed buffer after indoor floor applications to bring up a light shine and remove any residue caused by over-application.
DCI Penetrating Lithium Based Sealer Hardener will extend the life of any exterior concrete slab by reducing spalling and other problems caused by extreme weather conditions. If desired, Lithium Based Hardener Sealer can also be used in conjunction with other membrane-forming sealers for a glossier finish. As a penetrating sealer, DCI Penetrating Lithium Based Sealer Hardener is the choice for interior/exterior polished concrete countertops. Apply to either integrally colored or acid stained countertops and polish to a mirror-like finish.
Depending on slab porosity and surface conditions, 400-500 sq. ft. per gallon for smooth concrete. Stamped, heavily textured, broom finishes are not good candidates for this sealer. Surfaces heavily treated with sealer, paint, and mastic removers or citrus cleaners should not be sealed with DCI Penetrating Lithium Based Sealer Hardener. Do not apply in hot, windy conditions. Also available in sample sizes for testing or smaller projects.
Apply pump-up fence and deck sprayer. Spray enough sealer to create a uniformly damp surface. Do not over apply. This sealer does not form a surface membrane and should not be applied in “coats.” Use a squeegee to prevent pooling and ensure the sealer has been absorbed into the concrete. Apply more sealer only to areas that appear more absorptive than others. Sealer should remain uniformly damp for 20 minutes. Allow concrete to dry for 24 hours before buffing the floor with a high-speed commercial buffer for enhanced durability, light shine and remove excess sealer residue. The concrete will continue to harden over 7 days. On acid-stained floors, the surface must be fully neutralized and all remaining debris or excess color removed before sealing. If concrete has not been properly neutralized and cleaned, a temporary “white dusting reaction” can occur; it will typically disappear within two weeks of application. For vertical applications, apply from the bottom up using a low pressure, 10-25 psi sprayer with a fan-type nozzle. Flood surface until excess runs down 6” to 8” below spray pattern nozzle or sponge surfaces sufficiently to create a uniform dampness. When a brush or roller is used, repeated applications should be made until the surface remains moist for a minute or so before solution disappears. Use cleansers with a neutral ph only for floor maintenance. See application instructions for complete details. Clean up tools and sprayers with soap and water.
Spray on the surface and carefully squeegee off any excess sealer. Once the surface has remained uniformly damp for 20 minutes, leave to dry and polish after 24 hours dwell time.
