KorTek 917 Lithium Silicate Concrete Densifier

Dymond KorTek 917 is an extra-strength, water-based lithium concrete densifier designed to chemically harden, dustproof, and fortify concrete and cementitious substrates. It penetrates into the surface and reacts with the concrete to improve abrasion resistance, durability, moisture resistance, and protection against wear while keeping the substrate breathable. KorTek 917 is ideal for concrete floors, sidewalks, driveways, cement surfaces, natural stone, and precast stone where a stronger, longer-lasting surface is required without changing the overall appearance of the substrate. Key Benefits Extra-strength lithium concrete densifier One-component, water-based formula No VOCs Helps harden and fortify concrete surfaces Reduces concrete dusting Improves abrasion resistance and surface durability Helps protect against wear, moisture damage, and efflorescence Maintains breathability Normally does not change the appearance of the substrate No primer or topcoat required Can be applied by sprayer, mop, brush, or other suitable method Recommended Uses Concrete floors Garage floors Warehouse floors Workshops Sidewalks Driveways Cementitious substrates Natural stone Precast stone Dusting concrete surfaces Exterior concrete exposed to weathering How KorTek 917 Works KorTek 917 uses lithium densifier technology to react with cementitious ingredients within the substrate. Once the reaction occurs, the treated surface becomes denser, harder, and more abrasion resistant. Unlike a traditional film-forming sealer, KorTek 917 becomes an integral part of the surface. It does not create an impermeable coating, so the concrete remains breathable while gaining improved protection against wear, dusting, moisture, and surface deterioration.

Keep from freezing. Why Choose Dymond KorTek 917? KorTek 917 is a strong choice when you want to improve concrete performance without installing a visible coating system. It helps harden weak or dusting concrete, improves surface durability, and protects the substrate while preserving the natural concrete appearance. For industrial floors, commercial spaces, driveways, sidewalks, and concrete substrates exposed to everyday wear, KorTek 917 strengthens the concrete from within rather than simply sitting on top of the surface. Frequently Asked Questions What is KorTek 917 used for? KorTek 917 is used to densify, harden, and dustproof concrete, cement, natural stone, precast stone, sidewalks, driveways, and floors. Is KorTek 917 a concrete sealer? KorTek 917 helps reduce water absorption, but it is not a traditional film-forming sealer. It penetrates into the concrete and reacts with the substrate while allowing the treated surface to remain breathable. Will KorTek 917 change the appearance of my concrete? Normally, KorTek 917 does not significantly change the overall appearance of the substrate. After drying, the treatment is usually not readily visible, except the concrete has been fortified and strengthened. How much coverage will I get? Coverage depends on the absorptivity of the substrate. Typical coverage is 100 to 400 square feet per gallon when the surface is fully saturated. Does KorTek 917 require a primer? No. KorTek 917 does not require a primer. Does KorTek 917 require a topcoat? No. A topcoat is not required. Multiple coats of KorTek 917 are compatible, although one coat is normally sufficient. How long should KorTek 917 dry? Allow the treated surface to dry for 24 hours to obtain maximum benefit. Keep the floor dry and restrict traffic during this period. Can KorTek 917 be used outside? Yes. KorTek 917 is suitable for exterior concrete such as sidewalks and driveways, and it helps improve resistance to weathering and freeze-thaw effects. Can KorTek 917 be applied to damp concrete? The substrate can be damp, but there should be no standing water or puddles. Best results are usually achieved on a dry substrate.
