Formulated for brush, roll or spray application, the product is offered in a 5-gallon pail and provides long-lasting coverage across a wide range of substrates including EPDM, TPO, PVC, fiberglass, spray foam and metal. With a high Solar Reflective Index and an average coverage rate around 60 square feet per gallon, it reduces interior heat gain and helps preserve roof substrates without frequent re-coating.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly can I apply and finish a roof job with this silicone sealant?\u003c\/h3\u003e\n\n\u003cp\u003eMarlin’s silicone is designed for one-coat application, drastically cutting labor time compared with multi-coat systems.
