Product features

Performance and advantages

Water-based, safe, non-toxic and environmentally friendly

Pre-proportioned two-component system; mix thoroughly without adding water

Type I provides excellent flexibility and good low-temperature performance

Type II provides good strength, water resistance and bond strength

Easy to apply on damp substrates, helping shorten the construction period

Tintable color improves coat identification and helps prevent missed areas

Typical application areas

Where this product fits

Kitchens, bathrooms, balconies and air-conditioner slabs

Indoor structures not subject to permanent water exposure

Type I: non-immersed structures requiring greater deformation accommodation

Type II: positive- and negative-side waterproofing in damp kitchens and bathrooms not subject to long-term immersion

Transport and Storage

The product is nonflammable and nonexplosive and may be transported as general cargo.

Protect from sunlight, rain, compression and impact; keep the packaging intact.

Store in a cool, dry, ventilated place; prevent the liquid from freezing and the powder from becoming damp.

Shelf life is at least 6 months; re-inspect before use after expiry.

Suitability depends on substrate condition, exposure, climate, detailing, film build and the approved project system. Complete a representative adhesion and compatibility trial before full application.
