NWT314 Water-Based Polyurethane Waterproof Coating

This product is formulated using a self-crosslinking acrylic emulsion as the base material, combined with specific amounts of modifiers, surfactants, additives, and pigments. The resulting coating film is tough and elastic, with strong adhesion; it forms a complete waterproofing system that combines rigidity and flexibility with the substrate, accommodates structural movement, and provides long-term waterproofing and impermeability.

Construction Methods

• Process Flow
• Key Construction Points

Substrate Preparation: The substrate must be secure, level, and solid, free of sharp edges, loose dust, oil stains, and visible water marks. Inside and outside corners should be rounded using cement mortar or sealant. Cracks in the substrate and grooves around pipe roots should be filled with sealant.

Waterproof Coating: For a film thickness of 1.5–2.0 mm, apply the coating in 3–4 coats. Apply the next coat only after the previous one has dried (typically after 6–12 hours), and ensure that the application direction of each coat is perpendicular to that of the previous one.

• Important Notes

◎ Do not perform construction work at temperatures below 0°C or in the rain; it is not recommended to perform construction work in extremely humid or poorly ventilated environments.

◎ After the coating has dried, take care to avoid exposure to direct sunlight and washing away by rain.

• Recommended Dosage

For a 1.0 mm-thick coating film, the total paint consumption is approximately 1.8–2.0 kg/m².

Applications

Suitable for waterproofing and seepage prevention projects on roofs, basements, restrooms and bathrooms, bridges, and culverts of various types of buildings;

It is particularly suitable for waterproofing projects on flat roofs and buildings with irregular shapes.

Packaging, Storage, and Transportation
