Concrete Hardeners/Densifiers
Both of our hardeners are easy to apply and provide almost immediate hardening and sealing benefits. Our hardeners offer long-term protection with a single and simple spray-on application (watch Application Video below). Protect your floors with Harden X or Harden X SI and Discover the Benefits of Lithium!

Advantages of Lithium Technology
  Chemical reactions of lithium silicates are more stable than those caused by volatile conventional silicates, allowing the material to penetrate and react more evenly throughout the concrete for maximum hardening, sealing, and densification. Other silicates absorb moisture and cause ASR, weakening the substrate over time. Lithium silicates are insoluble, providing maximum water resistance. The cutting-edge technology in our proprietary lithium formulations make SealSource® products the most advanced in the industry.
