A: Polyurethane coatings offer high elasticity, chemical resistance, and strong bonding, ideal for concrete, pools, and wet rooms. MS coatings (如 JWS-001) are odorless, self-leveling, UV resistant, and decorative, suitable for interiors, roofs, and surfaces requiring a smooth finish.
A: For bathrooms and kitchens, we recommend JWS-001 MS Coating for its odorless application, smooth finish, and mold resistance. For high-moisture areas like shower floors, WP-001 Polyurethane Coating provides extra elasticity and durability.
A: No. Surfaces must be clean, dry, and free of dust, oil, or loose materials before application to ensure proper adhesion and waterproofing performance.
A: Typically 2-3 coats are recommended.
Touch-dry: 4–6 hours
Re-coat time: 20–24 hours at 25°C
Full cure: 3–4 days before exposure to water
A: You can use a brush, roller, or squeegee depending on the product. Serrated trowels are recommended for MS coatings to ensure even thickness.
A: Coverage depends on thickness:
1.0mm thickness: ≈1.3–1.5 kg/m²
1.5mm thickness: ≈2.0–2.5 kg/m²
2.0mm thickness: ≈3.0–3.5 kg/m²
