Concrete Surface Hardener
Concrete Surface Hardener is a penetrating liquid hardener that can effectively penetrate 3 to 10 millimeters of the cement surface layer. It reacts with the molecular substances inside the concrete to enhance the hardness and strength of the surface layer, helping to solve issues like dusting and sand shedding on the concrete surface. In waterproofing applications, especially on aged roof or floor or wall, this product can be sprayed on the base surface first to improve its hardness, making it easier for subsequent waterproof coatings to adhere.
Single-component / Eco friendly / OEM Accepted
APPLICATION RANGE
This product can be used for situations such as loose dusting on concrete surfaces, insufficient wall hardness, loose floor coating substrates, and reinforcement of waterproof surfaces. It solves problems such as concrete dusting, easy weathering, poor abrasion resistance, oil seepage, and the formation of cracks.

Note:
Before spraying a large area, you can perform a small sample test. If, during the first coat application, you notice excessive penetration or rapid drying, apply the second coat after 30 minutes. If it still dries too quickly, a third coat may be needed, which indicates severe sand shedding. However, if the first coat penetrates slowly, the surface becomes deeply moist, or there is pooling, one coat is sufficient.
