Polymer Modified Asphalt Waterproof Coating
Description
Polymer Modified Asphalt Waterproof Coating is an ultra-fine, suspended high-performance water-based asphalt coating formed by a special process of SBS, asphalt and additives. This coating is formed to waterproofing membrane by traditionally application of one cloth and two coatings,or two clothes and three coatings. The coating has excellent elasticity, self-healing properties, cohesiveness, and anti-aging properties. After the application, a seamless waterproofing membrane is formed, which is still called a liquid waterproof membrane.
Feature & Benefit
1. It can be sprayed or rolled, with high efficiency, seamless connection and no water channeling. It is applied best specifically to objects with special-shaped structures or complex shapes.
2. It has strong adaptability to the base level, and can be used on base materials, such as reinforced concrete, profiled steel plates, plastics and various masonry materials.
3. The surface treatment is simple, and it can be directly constructed without floating dust and water.
4. The coating has excellent weather resistance, acid and alkali resistance, and aging resistance. It does not require a surface protective layer, which can effectively reduce costs.
5. Water-based waterproof coating, environmentally friendly and harmless, with excellent elasticity and bonding ability.
6. The waterproof membrane is formed by the application of one cloth and two coatings or two clothes and three-coating on site, which is convenient to use.
Main Application
It is widely used in roofs, exterior walls, balconies, indoors, basements, pools, reservoirs, and other parts that need to be waterproofed, as well as key projects, bridges, tunnels, roads, and other projects.
Application Guidance
1. Clean the substrate where the water, floating dust, oil stains, mold release agent and other stains are on. The substrate should be smooth, firm, free from looseness and sand.
2. Node treatment: Plug and seal the special nodes such as the insdie and outside corners, joints, separation seam, and junctions of different materials, and then coat the nodes first.
3. Brush or spray a large area, and the construction thickness is about 0.5-1.0mm, and after the film is dried, paint the second time, the thickness is about 0.5mm. Do not wait for the film to dry, compact the cloth on the surface of the coating, and wait for the coating to dry. After that, apply the last time, about 0.5-1.0mm.
