Two-component polyurethane waterproof coating

Scope of application

It is suitable for waterproof construction of various civil and industrial buildings such as level, basement, toilet and swimming pool. It is more suitable for waterproof projects with complex shapes and vertical and horizontal parts of pipes.

Features

●After curing, the two-component polyurethane waterproof coating forms a seamless, complete elastic waterproof layer, which improves the waterproof and impermeability of the construction project, which is not achieved by the waterproofing of the coil, especially the coating film has high strength and extension It has strong adaptability to cracking or expansion of the grassroots.

●It is firmly bonded to the base layer, and the coated waterproof material has strong adhesion to concrete, wood, metal, ceramics, and asbestos tiles, and can also be used as an adhesive.

●Convenient construction. Polyurethane coating is a cold construction waterproof coating. During construction, only the two parts of A and B need to be mixed in proportion and brushed on the waterproof base layer.

●Easy maintenance, only need to repair the damaged parts locally, it can still achieve the original waterproof effect, saving time, labor and low cost.

●Environmentally friendly products, with low odor, reducing the impact and damage to people and the environment, is an ideal tar polyurethane replacement product.

Construction process

●The base layer needs to be firm, smooth and free of debris. The female and male corners should be rounded. The female corner diameter should be greater than 50mm and the male corner diameter should be greater than 10mm. Ingredients and dosage: According to the construction dosage, stir and use evenly. The reference dosage is: the dosage of 1mm thick coating is about 1.3-1.5kg / m2.

●Large-area waterproof construction: apply the mixed paint evenly with rubber or plastic scraper, the thickness is required to be the same, generally 1.5mm-2.0mm, it should be applied in 3 to 4 times, and the subsequent paint should be applied before After curing and forming a film, and painting in a vertical direction, it is generally a separate film, and an additional layer of carcass reinforcing material should be laid on the underground engineering floor.

●Thickness of coating film: 1.2-2.0mm for underground works, generally 1.5mm, and toilet room should not be less than 1.5mm. When exposed roofing works adopt multiple waterproofing, each thickness is not less than 1.2mm, and the waterproof level is III When a roof is fortified, the waterproof thickness is not less than 2mm. When the carcass reinforcement is laid between the coatings, the thickness of the coating under the carcass is not less than 1.0mm and the coating on the top is not less than 0.5mm.

●Construction of the finish layer: Before the final coating, the sand is skimmed and cleaned on the surface before the paint is cured.

●Protective layer: The surface of the coating waterproof layer should be isolated and protected according to the design requirements.
