产品描述

 


 

product description

 

It is a two-component waterproof coating. The component A is an organic liquid material composed of a polymer emulsion such as an acrylate emulsion or an ethylene-vinyl acetate copolymer emulsion and various additives. The component B is made of special cement and quartz sand. Inorganic fillers such as light and heavy calcium carbonate and inorganic powders composed of various additives, the components of A and B are properly mixed and mixed to form a two-component, water-based building waterproof coating. It has the dual characteristics of high elasticity of organic materials and good durability of inorganic materials.

Polymer cement waterproof coating (JS) is a green and environmentally friendly waterproof coating, and can adjust the color according to needs. It is recommended by the state for residential building waterproof coating.

 


 

Features

 

The coating has a certain gas permeability, and even if the base layer is wet, the drum phenomenon does not occur, and the base surface can be directly constructed regardless of whether the base surface is wet or dry, and the façade does not flow;

 

The coating has the characteristics of high strength, toughness, water resistance, weather resistance and durability.

 

Non-toxic, odorless, non-polluting, easy to work, short construction period, strong adhesion to the base surface;

 

The color is adjustable and has the dual function of waterproof decoration.

 


 

Specification model

 

According to physical and mechanical properties, it is divided into type I, type II and type III.

 


 

Scope of application

 

It can be applied on dry or wet masonry, mortar, concrete, metal, wood, hard plastic, glass, gypsum board, etc., industrial and civil old and new buildings (eg: houses, walls, underground, tunnels, bridges, pools, Bathroom, kitchen) can be used.

Construction process
 
 

Grassroots processing:

 

The base surface should be smooth, solid, free of sharp objects, floating dust, and oil stains.

 

The yin and yang angles and the root of the pipe should be rounded, and the radius of the corner should be greater than 50mm. The radius of the anode angle should be greater than 10 mm.

 

The unevenness and cracks must be leveled first, and the leaks must be treated first.

 

Ingredients:

 

If it is necessary to add water, first add water to the liquid material, slowly add the powder with a stirrer, stir for 5 minutes, stir evenly until the material contains no agglomerates, and the good material should be used up within 2 hours, otherwise the viscosity will rise. High will affect construction.

 

The weight ratio of the paint is compounded according to the proportion on the product packaging, and the amount of water can be adjusted appropriately to adjust the viscosity of the paint to meet the construction of different parts of the façade and the plane.

 

Large face brushing:

 

The sealing material is embedded in the groove, and the details such as the yin and yang angle and the tube root should be applied many times (2-5 times), and a layer of the carcass reinforcing material should be added to the underground project. Large-area construction waterproof coatings should be painted many times, usually 3 layers, special works can be painted in 5 layers.

 

The coating time of each layer is generally 8 hours apart, and the winter season should be extended. The thickness of each coating film is 0.4-0.5mm. It should not be too thick. The construction of the façade should be done without adding water or adding less water to avoid the flow of paint.

 

When adding the carcass material, the carcass should be flattened, no wrinkles, lapped not less than 100mm, first apply the paint once during construction, and then apply the paint again after the paving.

 

After the completion of the acceptance of the waterproof layer of the coating film, the finished product shall be protected.
