Crack RX is a light gray polyurethane caulk used to seal and close small gaps and cracks in the substrate prior to applying Pond Shield nontoxic epoxy. Applied with a simple caulk gun, Crack RX is capable of bridging even large cracks. It dries fast and once cured, it can be sanded and painted over. Will bond to porous and nonporous surfaces and is completely cured within 24 hours. Has excellent tear and general abrasion resistance as well.
