6. A-Primer will dry fairly quick and remains tacky, you may want to work in 1 arm length at a time. It is then ready to coat over with Liquid Rubber Smooth Sealant.
7. Apply Liquid Rubber Smooth Sealant on primed surfaces and Seam Tape. You will require several coats to achieve a water resistant surface. 3 Coat final coverage is approximately 30 sq ft/G. Dry time usually is approximately 3 hours between coats. When it feels dry to touch, it can be recoated.
