Two-component oil-based polyurethane waterproof coating

※  Product Description

Product Overview:Our Two-Component Oil-Based Polyurethane Waterproof Coating offers exceptional durability and superior waterproofing for a wide range of surfaces. Engineered for both indoor and outdoor applications, this advanced coating provides a resilient barrier against water, chemicals, and environmental elements.

Composition:This coating consists of two components:

Component A: A high-performance oil-based polyurethane prepolymer that provides excellent adhesion and flexibility.

Component B: A specialized hardener that enhances the coating's strength, durability, and resistance to wear and tear.

※  Application

 1.Wall surface, basement, tunnel, kitchen, swimming pool, subway, bathroom and so on.

      2.Especially used for the place where the shape is complex and irregular. 

※  Material Features

Superior Waterproofing: Forms a seamless, waterproof membrane that effectively prevents water infiltration.

Enhanced Durability: Resists abrasion, chemicals, and UV exposure, ensuring long-lasting protection.

Excellent Flexibility: Accommodates surface movement and thermal expansion without cracking or peeling.

Easy Application: Can be applied using a brush, roller, or spray, providing versatility for various projects.

Quick Curing: Achieves rapid drying times, allowing for faster project completion.

Application

Oil-based polyurethane waterproof coating has been widely used in the roofs, external walls, basements, balconies, kitchens, and lavatories of general buildings, and even some special edifices such as civil air defense works, bridge projects, and granaries.

※ Construction Requirments

1. Keep the base firm, smooth,clean, no dust, oil and visual water.

 2. Brush directly after stirring SPU Coating evenly.

 3. Brush in large area: Brush SPU on the substrate with rubber scrapper, and guarantee suitable strength, uniformity and no stack.

 4. Recommended thickness is not beyond 0.7mm at per coating film, and two or three times coating film is better.

5. Do the second time's brush after the first film is dry, namely non-stick with hand. Remember the brushing direction is orthogonal with the last film, until reaches the design thickness.

 6. If necessary add some water whose weight is about 10% of the coating, stir evenly not less than 3min by electric mixer.

※ Construction Methods

Two Component Polyurethane Waterproofing Coating can use construction methods as below: brushing, roller coating, spraying, etc.

※Storage and Transportation

 1. In a cool, dry place, away from direct sunlight, damp and fire.

2. The storage period is half a year. After the expiration, it shall be tested again. It can be used again after passing the test.

3. Upside-down piling, not more than three layers.

4. The product is a combustible material, so during transportation, great importance shall be attached to safety. Care must be taken against catch-on-fire; 

it must be kept away from rain, insolation, extrusion, and collision. The package shall be kept intact and in compliance with relevant regulations of the transportation

 department.
