Product overview

Product overview and technical properties.

Vapor-Permeable High-Elastic Waterproof Coating is a one-component, non-exposed, environmentally responsible water-based waterproof coating. It is formulated with a special emulsion as the main film-forming material, selected pigments and graded fillers, and functional additives. It prevents external water from seeping in while allowing internal water vapor to escape, providing combined waterproofing and vapor-permeability protection for exterior walls.
