How to Apply

COVERAGE: .46-2.3 sq. meters=5-25 sq. ft. Shake can before application. Apply in even coats at a distance of 8”- Can be applied up to 100 mils. (3/32”) per application. Allow colour to turn black between coats. Rubber Shield™ can even be re-coated almost immediately, because of its unique air-drying capabilities. This allows you to build-up a thicker, water-proofing seal for maximum protection. When done, invert can and spray to clear nozzle.
