Concrete Densifier Plus Water Repellent – SD600

A non-hazardous, densifier, hardener, and water proofing sealer for new and existing concrete surfaces. Treated surfaces are resistant to water damage and surface abrasion/cracking while reducing dusting and simplifying maintenance

SD600 is a multi-phase penetrating lithium-colloidal based proprietary silicate treatment that reacts with concrete to produce insoluble calcium silicate hydrate that locks aggregate together and fills vacant concrete pores strengthening and hardening concrete while building a water-resistant matrix. SD600 will not contribute to surface ASR (Alkali Silicate Reaction).

The tetrahedral silicate monomer technology incorporated in SD600 provides water repellant protection superior to silane and siloxane emulsions, silicates, petroleum distillates and other common water repellants.
