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).
