GII features up to 120% elongation rate to bridge 2mm wide substrate cracks from thermal expansion, building settlement and vibration, while supporting both positive and negative side waterproofing with maximum 0.8MPa negative pressure resistance. It achieves 1.0MPa tight skin-like adhesion on concrete and masonry, preventing peeling and delamination, and passes strict impermeability tests under 0.3MPa positive water pressure, offering stable long-term leak protection for basements, tunnels and bridge joints.
This solvent-free, water-based two-component mortar is non-toxic and odorless, fully compliant for drinking water tanks and closed indoor wet zones like bathrooms and kitchens. It stands up to long-term UV aging and acid/alkali erosion with over 80% tensile strength retention after 168h alkali soaking, suitable for outdoor roofs, balconies and long-term immersion swimming pools. It can be applied on damp non-ponding substrates via brush, roller or trowel, forming seamless waterproof film without complex surface pretreatment..
Mix liquid and powder at a 1:1.5–2.5 weight ratio, stir evenly and apply in 2–3 thin cross coats to reach total 1.2–1.5mm thickness; complete natural curing for 48 hours before light use, full strength develops after 7 days. Its matte rough surface improves tile and plaster adhesion after waterproof construction, saving separate interface treatment steps and lowering overall project cost. Stable performance, simple operation and wide compatibility make it the all-in-one flexible waterproof choice for residential renovation and large infrastructure projects.
