Product overview
Performance and application overview.
Neoprene latex mortar or RF cationic neoprene latex waterproof and anticorrosive mortar, is formulated from high-molecular polymer emulsion, special cementing materials, and premium aggregates through a specialized process.
This mortar stands out for its exceptional adhesion, crack resistance, frost resistance, anti-seepage, anti-corrosion, chloride ion penetration resistance, abrasion resistance, and anti-aging qualities.
It's widely used in strengthening building structures, waterproofing air defense facilities, preventing seepage in reservoir dams and ports, protecting chemical corrosion-prone areas like thermal pools, landfills, chemical warehouses, and tanks, repairing concrete on roads, bridge decks, tunnels, and culverts, and handling anti-leakage for roofs, bathrooms, and basements in industrial and civil buildings.
It also works well for waterproofing steel structures and reinforced concrete, with the added advantage of direct application on wet bases and strong bonding to various substrates. Suitable for projects in water conservancy, ports, highways, bridges, metallurgy, chemical industries, and more.

Product usage
Application and installation guidance.
For construction process:
Prime the surface with an even coat of neoprene latex cement mortar; apply the main layer once it's touch-dry.

Apply in strips or staggered blocks (max 12m² area, 1.5m width); maintain 24h intervals for joints. Pre-fix joint strips on slopes, remove after application, then seal seams with neoprene cement paste and mortar. Stagger joint positions in layered work.

Spread and press the mortar firmly, smoothing in one pass; pierce bubbles for a dense finish. For vertical or overhead surfaces over 10mm thick, layer in 5-10mm increments, proceeding when previous layer is touch-dry.
