JS Polymer Cementitious Waterproof Coating

Product advantages

1. It has a certain degree of flexibility, good bonding performance, and can be constructed on a wet base surface;

2. Good weather resistance, high and low temperature resistance; less dosage, low cost, non-toxic and harmless, non-polluting, and easy to construct;

The scope of application

1. It is widely used in waterproof, anti-leakage and moisture-proof  projects  for exterior walls, toilets, baths, kitchens, swimming pools, basements, roofs and other buildings;

2. It is used to prevent leakage and moisture of porous material masonry such as aerated concrete and hollow bricks;

Base preparation

1) The substrate must be firm, flat, clean, free of dust, greasy, wax, release agent, etc. and other debris;

2) All small pores and sand holes can be mixed into a wet mass with the plugging king and a little water, and then smoothed;

3) Before applying the slurry, fully moisten the substrate in advance, but there should be no stagnant water;

Construction technology

1)When using, mix the powder slurry and cement powder according to the required ratio:

• 1:1 for a flexible coating, suitable for floor and roof;

• 1:1.5 for a semi-flexible (neutral) coating;

• 1:2 for a rigid coating, suitable for wall surfaces;

2)For molsture-proof,one layer can be applled;for waterproof,at least twolayers should be applied.The multi-layer construction method should beadopted,and the standard amount shouldbe used for construction,and thethicknessof asingle layershould not exceed 1mm;

3)After the first layer is completely dry (about 2-4 hours), apply the second layer. The brushing directlon of the second layer should be perpendicular to the brushing direction of the first layer;

Matters needing attention

1. This product is suitable for use in an environment of 5℃ ~ 35℃, and must be protected from rain, hot sunlight and frost during the construction process;

2. The slurry after opening and adjustment should be used up within 2 hours. Do not mix the dried glue with water before using it;

3. After the waterproof layer is completely dried, other covering layers can be used;
