08 Concrete Surface Hardener (Sand Fixing Agent, Primer)
INTRODUCTION
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.
APPLICATION
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.
ADVANTAGES
Deep Penetration and Curing: Rapidly penetrates into the concrete substrate, fundamentally strengthening the base layer. It effectively addresses issues like sanding, dusting, aging, and loosening, with a penetration depth of several millimeters, ensuring a long-lasting reinforcing effect.
Enhanced Substrate Strength and Hardness: Significantly increases the surface strength of concrete and cementitious substrates, making them harder and more wear-resistant. This reduces wear, chipping, and cracking caused by external forces or natural weathering, extending the substrate's service life.
Convenient Application: Ready to use directly from the container. No mixing or special equipment is required. It can be applied via cold spray, roller, or brush, making the operation simple and straightforward.
High Bonding Strength: Forms a solid, monolithic bond with the substrate, enhancing the adhesion of subsequent finishing materials (such as tiles, putty, and paint) to the base. This reduces the risk of hollowing and delamination, ensuring construction quality.
Environmentally Friendly: This product is a water-based, eco-friendly material and is safe to use.Enhanced Water Resistance: Increases water tightness and surface strength.
