Finestop RS

Finestop RS is a one-component, fluid-applied vapor permeable vertical above gradeair/water-resistive barrier with built in low temperature application properties. This resilient waterproof coating can be applied directly to approved, above-grade wall substrates by sprayer, roller, brush or trowel. It provides excellent secondary moisture protection behind most wall claddings including EIFS, stucco*, brick, siding and metal panels. Finestop RS is listed in ICC Evaluation Report ICC ESR-2986.

*A slipsheet is required for stucco claddings

Advantages
One continuous air/water-resisitve barrier for buildings with multiple claddings (can be used with most code-compliant claddings)
Can be used with most code-compliant claddings. Meets ASTM D1970 nail sealability requirements with and without Sheathing Fabric
One component, easy to apply formulation that meets low VOC requirements in all 50 states
Nonflammable as applied
Will not dry out or crack due to loss of oil/plasticizer over time
Cleans up with water; solvents and citrus based cleaners not required
Rugged membrane resists damage after installation
Low temperature performance down to 25°F (-4°C)
Allows for flexible construction scheduling with an 180 day outdoor exposure rating (30 days if used as part of an adhesively attached wall system)
