Advantages and disadvantages of js waterproof coating and its construction method

The more kinds of coatings, the more attractive they are to consumers. Js waterproof coating is also one of them. So what is js waterproof coating? Let's take a look at the advantages and disadvantages and construction methods of js waterproof coating!

What is js waterproof coating?

Js waterproof coating refers to polymer cement waterproof coating, also known as js composite waterproof coating. Where J refers to polymer and S cement ("js" is the phonetic prefix of "polymer cement"). Js waterproof coating is a two-component, waterborne building waterproof coating, which consists of organic liquid materials such as polyacrylate emulsion and ethylene-vinyl acetate emulsion and various additives, as well as inorganic powder materials such as cement, quartz sand, light and heavy calcium carbonate and various additives.

Main features of js waterproof coating:

1, wet surface construction; The coating is tough and has high strength.

2. Adding pigments can make colorful decorative layers.

3, non-toxic, tasteless, can be used for waterproof of edible pools.

4. It is suitable for waterproofing of exterior walls and sloping roofs with decorative materials, as well as the construction of facades, sloping surfaces and top surfaces, and can be firmly bonded with various external materials such as base surfaces and decorative bricks, roofing tiles and cement mortar.

5, high temperature resistance (140℃), especially suitable for road and bridge waterproofing.

6. By adjusting the mixture ratio, ceramic tile bonding materials and sealing materials can be made.

Advantages of js waterproof coating:

1, js waterproof coating is a green material, which does not pollute the environment, has stable performance, excellent aging resistance and long waterproof life;

2. It is safe to use, convenient to construct and simple to operate, and can be directly constructed on the wet base surface without Mingshui;

3. The bonding strength is strong, and the bonding strength between the material and the cement base surface can reach above 0.5MPa, which has good bonding performance for most materials;

4. The material has good elasticity, and the elongation can reach 200%, so it has excellent crack resistance, frost resistance and low temperature flexibility;

5, good workability, no foaming, good film forming effect and fast curing;

6, the construction is simple, brush coating, roller coating, scraping coating construction can be.

Js waterproof coating disadvantages:

Js waterproof coating construction temperature should be higher than 5 degrees.

It is not suitable for construction in rainy days or when there is open water at the grass-roots level. Construction method of js waterproof coating

Stirring: firstly, pour the liquid material into the container, then slowly add the powder material, and fully stir for 3-5 minutes, until a uniform slurry without original powder lumps and particles is formed, which can be used; (It is best to use a blender)

Brushing: Brush directly on the base surface with a brush or roller brush.

Force evenly, do not miss the brush; Generally, it needs to be brushed twice (depending on the use requirements), and the thickness of each brush shall not exceed1mm; After the previous one is slightly dry, brush the next one (it is not sticky, usually with an interval of 1-2 hours), and brush the front and back vertically and horizontally, with a total thickness of1-2 mm; If the coating has cured, wet it with water before applying another layer. Maintenance: It is recommended to cover the coating with wet cloth or spray water to maintain the coating after 24 hours of construction.

Protection: please pay attention to prevent trampling, rain, sun exposure, sharp instrument injury, etc. Before the building is completely dry.

Inspection (closed water test): Please store water for 48 hours (at least 24 hours in summer and at least 48 hours in winter) after the waterproof layer is dry, and check whether the waterproof construction is qualified. The lightweight wall needs to be watered thoroughly.
