Product overview


Dayu®Polymer cement waterproof coating, is a two-component reaction volatile curing water-based waterproof coating. When in use, the and B components are uniformly coagulated according to the specified proportion, and after brushing, they react and volatilize on the base surface, and cure to form a dense coating waterproof layer.


l  A component:Polyacrylate emulsion or ethylene vinyl acetate copolymer emulsion with a variety of additives composed of organic liquid material.

l  B component: by special cement, quartz sand, calcium carbonate and other inorganic powder according to a certain proportion of mixing.




Product Features


l Better extensibility and water resistance.

l Good bond strength, weather resistance and durability.

l Wet base surface can be constructed.

l Water-based material, non-toxic and tasteless, green environmental protection.




Specification classification



Type I/Type II/Type III

Type I: grass-roots level with large amount of activity; Type II and Type III: grass-roots level and elevation level with small amount of activity



Scope of application


l It is suitable for industrial, civil, municipal and other construction projects, including administrative, residential, commercial, scientific research, medical, school, grain depot, pipe gallery and other buildings.

l Suitable for building basement, roof, toilet bath, swimming pool and other waterproof parts.

l It is only used for waterproofing the facing water surface of the fortified part.




Construction process


L grass-roots requirements: solid, clean, free of sediment, laitance, oil, no empty drum, loose, sand and other phenomena, yin and yang angle should be rammed arc angle.

l Ingredients: Weigh strictly according to the ratio marked by the packaging barrel, add component A to component B and stir well.

l Coating methods: scraping (scraper), rolling (wool roller), spraying (matching spraying equipment).

L primer: depending on the ambient temperature, add appropriate amount of clean water to dilute the coating, and evenly apply * thin coating to the base layer.

* Incorporation ratio: 10% ~ 30%.

* Thin coating: thickness should not exceed 0.3mm.

L surface coating: multiple thin coating films shall be formed, and the second coating shall be applied only after the front coating is completely dry (non-sticky), and the brushing direction of each coating shall be perpendicular to each other.

Each thickness: not more than 0.5mm, according to the design thickness to determine the number of brushing.

Reference dosage: 2.0~2.4kg/㎡ · mm.

Consistency adjustment: if the consistency is high and the construction is inconvenient, add a proper amount of clean water, which should not exceed 5% of the ingredients.

Strengthening treatment: Yin and Yang angle, node can be placed in the process of brushing alkali-resistant glass fiber mesh cloth, and in the appropriate thick coating.

L optional air defense drum measures: DingTalk hanging steel wire mesh, smearing interface adhesive and sand spreading on surface layer (priority is given in order).
