• Clean and safe during application  water-cleanable when fresh, non-flammable, generally low in odor. 

• Crack isolation / anti-fracture protection  can bridge non-structural cracks up to ~ 3 mm (1/8), protecting tile/stone finishing from substrate shrinkage or minor cracks. 

• Strong adhesion to many substrates  effective on concrete, cement mortar beds, cement plaster, cement backer boards, gypsum wallboard, brick or masonry, even exterior-grade plywood (check substrate suitability for exterior use). 

• Versatile use horizontal & vertical surfaces  suitable for wet areas like bathrooms, kitchens, terraces, balconies, utility rooms; also for exterior or interior applications depending on substrate. 

Typical Applications

• Bathrooms, shower areas, washrooms as a waterproof barrier under tiles/stone. 

• Kitchens, laundries, utility areas or other indoor wet zones. 

• Balconies, terraces, and other semi-exterior spaces (depending on substrate and local guidelines).

Packaging, Coverage & Standards

• Available in 5 L and 20 L pails

• Coverage: ~ 200225 sq. ft per 20 L pail (coverage may vary with substrate condition, thickness applied, and application method). 

• Meets recognized standards for waterproofing membranes (e.g. conforming to standards like EN 14891 / similar relevant specs). 

Important Usage & Installation Notes

• Substrate must be clean, sound, free of dust, oil, sealers, curing compounds etc. before application for optimal adhesion. 

• In areas with corners, coves, board joints, or changes in plane, its recommended to use reinforcing fabric along with the liquid membrane for improved waterproofing integrity.
