Application Sheet
Surface Preparation
Proper surface preparation is critical to the long-term performance of the Dura-Coat Rubber-Flex 900. The Surface must be clean and rough. Prepare using a power tool with a wire wheel. Clean with solvents (acetone, xylene, alcohol or MEK) and cloth towel. No need to use primers, Dura-Coat Rubber-Flex 900 go direct to the rubber or metal.
Mixing
Thoroughly mix Activator into Base with mixing stick scraping sides and bottom of container or mixing board. Mix by weight 9-parts Base to 1-part Activator. Mix thoroughly to produce an even colored and streak-free material. THINNING: Never thin.
Application
Dura-Coat Rubber-Flex 900 can be applied with a squeegee and putty knife.
To avoid sagging in vertical surfaces, the maximum recommended thickness per coat is 12,7 mm (500 mil).
