Product overview


Dayu®High elastic thick acrylic waterproof coating is a high-performance one-component waterproof coating, which is based on imported modified acrylate copolymer, added with a variety of imported additives and fillers, and processed by strict scientific process.




Product Features


L non-toxic, tasteless, green environmental protection.

L film high elasticity, high elongation.

l Acid resistance, alkali resistance, high temperature resistance, UV resistance and anti-aging *.

l Thermal dimensional stability, low temperature flexibility, good water resistance and crack resistance.

L can be wet, dry a variety of materials on the surface of the construction, high adhesion.

L color adjustable, both waterproof function and decorative effect.

* To add matching topcoat.




Specification classification


By Physical Performance

Type I/Type II




Scope of application


l Applicable to all kinds of old and new buildings, structures of the roof, wall, toilet bath, pool and other waterproof, impermeable and moisture-proof.




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 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: 2.0~2.6kg/㎡ · 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).
