Two-component · polymer–cement flexible membrane
K11 Waterproof Coating
YR-9(8)804-03
1 / 5
YRong two-component waterproof coating combines polymer emulsion with cement-based powder to form a tough, flexible membrane. Low VOC, workable on damp substrates without standing water, and tile-ready after curing—suited to kitchens, baths, balconies, and selected outdoor scopes.
Liquid polymer emulsion reacts with inorganic cement powder to create a flexible waterproof film that balances organic toughness with inorganic durability. Designed for indoor wet rooms and underground protection with proper detailing.
