3D Hybid Silicate Densifier is three densifiers in one with lower solids to penetrate even the most difficult, tight cap. It improves surface performance and resists the harmful effects of traffic wear and weathering. By having three different sized molecule silicates this product fully penetrates varying densities of concrete regardless of region or hardness. This improves the abrasion resistance for new or aged concrete. 3D HSL is ideal for use for exposed and polished concrete, as well as integrally colored cements. Hardens deep within the slab to improve durability even after grinding. Contains UV stabilizers to help protect color from fading. Ideal for new construction, existing concrete, and diamond pad burnishing. Enhances polished color, gloss and clarity. Provides superior stain resistance especially when combined with SR2 Sealer. Coverage rate is approximately 600 - 800 sq ft per gallon.
