Weidun® LQ01 Polyurethane Liquid Membrane: Benefits and Application Guidelines
Solvent-based polyurethane is Weidun’s most proud coating product, widely used in the vast majority of building exterior fields. Weidu®LQ01 Polyurethane Liquid Membrane have the advantages that other brands do not have, and can be adjusted according to the customer’s local temperature and humidity to speed up film formation, to save time and avoid the occurrence of work on the site.
Key Benefits
1. Superior Durability:
These coatings form a tough, flexible film resistant to abrasion, impacts, and heavy foot traffic, ideal for high-wear surfaces like floors, machinery, and metal structures.
2. Weather & Chemical Resistance:
Withstand UV exposure, extreme temperatures, and harsh chemicals (e.g., oils, solvents, acids), ensuring long-term protection in outdoor or industrial environments.
3. Enhanced Aesthetics:
Provide a glossy, smooth finish that retains color vibrancy and resists yellowing over time.
4. Strong Adhesion:
Bond effectively to metals, concrete, wood, and plastics, minimizing peeling or blistering.
5. Fast Curing:
Achieve hardness within 3 hours, allows 2 time brush in one day even in raining season.

Weidun®LQ01 Polyureathane Solvent-Free Liquid Membrane is liquid-applied polyurethane waterproofing membrane, solvent-free and is highly permanent elastic, cold applied and cold curing, a single component system design for long lasting waterproofing.
Application Steps
1. Surface Preparation:
- Clean the substrate thoroughly to remove grease, dust, or old coatings.
- Sand metal surfaces to eliminate rust; etch concrete to ensure porosity.
- Ensure surfaces are completely dry (moisture content <10%).
2. Priming (If Required):
- Apply a compatible polyurethane primer to metals or porous substrates to enhance adhesion and corrosion resistance.
3. Mixing & Thinning:
- Stir the coating thoroughly before use.
- Thin with recommended solvents (e.g., xylene) if needed, typically 5–10% by volume, to adjust viscosity for spraying.
4. Application:
- Use brush, roller, or spray equipment. For spray applications, maintain a 20–30 cm distance from the surface.
- Apply 2–3 thin, even coats, allowing 2–4 hours of drying between coats.
5. Curing:
- Allow 8 hours for light use and 24 hours for full cure. Maintain ventilation and avoid exposure to moisture during curing.
Best Practices
- Work in temperatures between 10°C and 35°C with humidity below 80%.
- Wear protective gear (gloves, masks) to avoid solvent exposure.
- Regularly inspect coated surfaces for damage and reapply as needed.
