Waterproof coating

Waterproof coating construction plan?

1. Clean up the base, the surface of the original wall should be solid, and there should be no sand, ash or empty drum.

2. Clean the root of the upper and lower water pipes and carry out plugging treatment.

3, with 10-15 mm wide paper according to the wall design construction height paste contour line.

4, the first time emulsion coating construction, order from top to bottom, from the inside to the outside, shall not miss the brush.

5, 24 hours after drying, besmear second times of emulsion, so that two times of emulsion form a complete waterproof layer.

6, dry 24 hours, do 24 hours closed water test, water height is not less than 30㎜,24 hours no leakage is qualified.

7, the surface cement mortar wool, can be directly attached to the brick construction.

What are the types of waterproof coating?

1, polymer - cement waterproof coating.It is a volatile curing type coating, mainly divided into two types: type I, polymer emulsion as the main component, add a small amount of inorganic active powder, after curing to form a flexible film, can be used in the face of the water as a waterproof layer;Ⅱ type, such as mud activity of inorganic powder is given priority to, add a certain amount of polymer emulsion coating, the curing forming elastic cement coating, can be applied to meet the surface and back surface waterproof construction.

2, acrylate waterproof coating.It is a volatile curing coating, with good weather resistance, suitable for exposed, non-exposed parts and waterproof construction facing the water surface.Emulsion type color acrylate waterproof coating with decorative function, suitable for roofing and wall waterproof and decoration.Polymer - cement waterproof coating, emulsion color acrylate waterproof coating can be in wet (anhydrous) or dry base surface construction.The film water resistance is less than 80% of the emulsion waterproof coating shall not be used in the basement and other long-term water soak waterproof parts.
