Liquid Bitumen Waterproof Coating for Roofing

Liquid Bitumen Waterproof Coating for Roofing is an one-component liquid applied elastic bitumen-modified waterproof coating.


Liquid Bitumen Waterproof Coating for Roofing is an one-component liquid applied elastic bitumen-modified waterproof coating. It will form a strong and tough waterproof membrance for the substrates where has been applied the coating.

High polymer emulsified modified asphalt waterproof coating is mainly use asphalt as raw materials, with water as the dispersion medium, with other polymer such as SBS or APP to modified the asphalt, finally launch out this polymer modified asphalt waterproof coating. As soon as coating is curing at normal temperature, the materials can be formed on the surface a layer of elastic waterproof film, it can be work along to function as waterproof coat, and also can be compound with waterproof membrane to form compound waterproof system.


Features

1.The material is a water-based product, with non-toxic, no smell, non combustible characteristics, safe and reliable;

2.The material is a single component, cold method construction, simple operation;

3.Acid and alkali resistance, aging resistance, long service life;

4.The film has good flexibility, crack resistance and heat durability, good adhesion, is a kind of ideal waterproof material;


Where to apply

1.Non exposed waterproofing of roof and underground structures.

2.Compound with all kinds of modified bitumen waterproofing membrane to composite strong waterproof layer.

3.As basic treatment agent for all kinds of modified bitumen waterproof membrane.

4.Can be directly coated in a variety of pipe, concrete surface to function as protection, anti-corrosion effect.


Substrate Requirement

Substrate surface should be clean, dry, firm and smooth.


How to apply

Substrate should be coated for several times. Stirring the coating and brushing the substrate evenly by rubber scraper. The next painting can be started after the former painting surface dry. The direction of former and latter coating should be mutually perpendicular. Several times of coating are needed to ensure penetration and adhesion of paint to the substrate. Surface drying time is about 6 hours at normal temperature.
