The reaction mechanism of Weigu 929 is that the NCO end group of the PUP touches air or the tidal air of the basement layer that they solidify into films, it can construct in moist base course and complicated projects. There will be a seamless, strong bonding, stretchy and tough waterproof film.
Main performance
One-component packaging, ready to use, avoid unstable condition when mixing
Anti-aging, acid & alkali resistance, high & low temperature resistance performance

Non exposed roof, underground waterproofing, kitchen & bath and non drinking water project
Technical Data Sheet
Construction Method
Main points of application
The surface should be clean and firm, repair flaw part beforehand.
Detail parts treatment: Coat a layer on the internal and external corners and the part of pipeline bottom, and then apply reinforce layer (non-alkali fiberglass fabric or non-woven fabric), make sure that the coating saturate completely the reinforce layer.
Application of basement layer: you may add some basic primer to strength the closure and permeability.
Multi-layer application: apply the coating on the substrate evenly, and then apply with vertical direction for next coating. The surface drying time is about 12 hours, the waiting time base on the first layer which touch to be non-stick, generally apply 2~3 times (or according to the design requirements).
The thickness of the coating should be 0.5~0.8mm.
Recommended application for substrate: primer: principal material = 1:2 (weight), apply after mixing.
Packaging & Shipping
