XB-9200-23 Polymer Cement (JS) Composite Waterproof Coating

Product Presentatio 
JS composite waterproof coating is a green and environmentally friendly waterproof coating, which is recommended by the country as a waterproof coating for residential buildings. This material is a two-component waterproof coating composed of organic liquid material and inorganic powder material, which has the dual characteristics of high elasticity of organic materials and good durability of inorganic materials. After coating, it can form a high-strength and tough waterproof coating.

Product Performance 
★ Can be directly constructed on damp or dry substrates of various materials, without flowing on the facade;
★ The coating has high strength, toughness, water resistance, weather resistance, and excellent durability;
★ Can add pigments to form a colored coating;
★ Water based coating, non-toxic, odorless, pollution-free, and environmentally friendly;
★ Simple construction, short construction period, can be carried out on damp substrates, strong bonding strength;
★ The coating has a certain degree of breathability, and even if the base layer is damp, there will be no bulging of the waterproof layer.

Scope of Application
Both old and new civil buildings (such as bathrooms, kitchens, houses, interior walls, underground, tunnels, bridges, pools, reservoirs, etc.) can be used.

Construction Technology
Grassroots treatment
The surface of the base layer should be flat, solid, free of sharp objects, floating dust, and clear of visible water and oil stains;
The internal and external corners, as well as the root of the pipeline, should be made into circular arcs, with the internal corner radius greater than 25mm and the external corner radius greater than 5mm;
Uneven and cracked areas must be leveled first, and leaks must be sealed first.
Mixed ingredients
If water needs to be added, first add water to the liquid material, slowly add the powder material while stirring with a mixer, stir for 5 minutes, stir evenly until there are no lumps in the material. The prepared material should be used up within 2 hours, otherwise the viscosity will increase and affect the construction.
The weight ratio method of the coating is based on the proportion indicated on the product packaging. The amount of water added can be adjusted appropriately to adjust the viscosity of the coating and meet the construction needs of different parts of the facade and plane.
Detail additional waterproof layer
Seal materials should be embedded in the grooves, and multiple coats (2-4 times) should be applied to details such as internal and external corners and pipe roots. An additional layer of tire reinforcement material should be added for underground engineering.
Construction of large waterproof layer
Waterproof coating for large-scale construction should be applied multiple times, usually in 4 layers, and for special projects, it can be applied in 5 layers. The interval between each layer of painting is generally 8 hours, and it should be extended in winter. The first layer of coating should be applied thinly with a thickness of 0.2-0.3mm, and the thickness of each subsequent layer of coating should be 0.4-0.5mm. The amount of coating used is about 0.8kg/m2, and it is not advisable to apply it too thick in one layer. For facade construction, it is better not to add water or add less water to prevent the coating from flowing and making it difficult for the facade thickness to reach the design thickness. At the same time, it may cause excessive accumulation of material at the internal and external corners, resulting in cracks. When adding tire body materials, the tire body should be flat, without wrinkles or folds, and the overlap should not be less than 100mm. During construction, apply a layer of paint first, and then apply another layer of paint coating on top. After the waterproof layer is completed and accepted, the finished product should be protected.
