Product Positioning
W802 is a primer and substrate-bonding layer. It is applied after W801 and putty, and before intermediate coats such as W803.
Primary Functions
It bonds the substrate to the functional coating layers above, enabling subsequent products such as W803, W813 and W823 to form a more complete coating-film system.
Core Advantages
Strengthens the bond between the substrate and intermediate coat; supports a continuous waterproofing system; is highly compatible with the W8 silicone rubber system; and contributes to overall coating stability.
Applications
Suitable for exterior walls, roofs and other projects requiring long-term waterproofing and protection.
Performance Characteristics
System compatibility, standardized installation and long-term durability.
