Polyaspartic Polyurea Waterproofing Application - Exterior Wall Waterproof Coating

With the economic development and social progress of the new era, people's demands for building quality, safety, and durability are constantly increasing. This is reflected not only in living comfort but also in the waterproofing safety of buildings.

Exterior wall transparent polyaspartic polyurea waterproof coating is formed by the reaction of high-purity polyaspartic polyurea resin with isocyanate prepolymer, creating a transparent waterproof layer. This product boasts superior waterproofing properties, excellent weather resistance, strong adhesion, and advantages such as flexibility, abrasion resistance, crack resistance, and eco-friendliness. It can be directly applied to substrates like wall tiles without peeling, chalking, or blistering. It effectively prevents water seepage in the base material, has a long service life, and provides reliable protection to enhance the waterproof durability of wall surfaces.

Product Advantages

1. The coating is colorless and transparent, preserving the original wall decoration effect without yellowing. It is washable, dirt-resistant, and offers anti-corrosion and anti-mold properties.
2. Features rapid film formation, strong adhesion, and excellent overall encapsulation.
3. High transparency, yellowing resistance, excellent weather resistance, and acid-alkali resistance.
4. Can be applied at 0°C, cures normally at -5°C, safe to operate, easy to apply, and can be directly painted, brushed, or troweled onto the wall.
5. No need for tile removal, low material consumption, and cost-effective.

Application Range

1. Waterproof repair for various building exterior wall seepages, balconies, wall tiles, marble, granite, and other surfaces, providing anti-corrosion and water-resistant coating.
2. Anti-corrosion and waterproof coating for inorganic materials such as cement, ceramics, and glass.
3. Decorative waterproofing (anti-mold) and anti-corrosion for balconies, new and old roof walls, and complex areas.

Application Method

1. Thoroughly clean the substrate, ensuring it is dry, oil-free, and dust-free. Strictly follow the instructions for mixing ratios. Apply by hand brushing, rolling, or high-pressure airless spraying, ensuring full coverage and saturation.
2. After completing the waterproof layer application, carefully inspect all parts of the project, especially the gaps between exterior wall tiles. The coating should not have any missed spots, delamination, curling edges, or cracks. Promptly recoat any areas found to be insufficiently covered.

Precautions

1. During application, ensure the product fully covers the substrate. Allow 24 hours of curing before proceeding with other operations.
2. In areas with high abrasion resistance requirements, apply the same grade of super-wear-resistant waterproof material on top to protect the film layer from damage.
