Product Positioning
W801 is a waterproofing mortar for substrate repair and leveling, rather than a final decorative finish. It is specified as a silicone rubber polymer-modified waterproofing mortar for exterior walls.
Primary Functions
Used for exterior-wall substrate leveling, localized damage repair and the first layer of basic waterproofing. In new exterior-wall systems, W801 provides waterproof mortar leveling; in tile-renovation projects, it can also repair and level localized areas of detachment.
Core Advantages
Strong substrate-repair capability; leveling and basic waterproofing in one material; a stable substrate for subsequent primer and intermediate coats; particularly suitable for localized repair of aged or damaged walls; and one of the foundational protective layers in the W8 system.
Applications
Particularly suitable for localized repair of aged and damaged wall surfaces.
Performance Characteristics
System compatibility, standardized installation and long-term durability.
