This is a revolutionary one-component polyurethane rubber-based wall decorative waterproofing material developed independently based on years of accumulated polyurethane technology. It does not allow water to pass through but does allow water vapor to pass, preventing swelling and peeling of the coating due to moisture in the substrate, and preventing condensation and mold growth inside the building. Additionally, it helps prevent the neutralization of concrete and the rusting of rebar, thereby improving the durability of the building. 【Features】 ■ Does not contain specific chemical substances ■ Excellent crack-following ability for substrates ■ Excellent cold resistance, heat resistance, and weather resistance ■ Excellent water vapor permeability ■ Prevents freeze damage and salt damage ■ Adheres well to various substrates *For more details, please refer to the catalog PDF.
