Frequently Asked Questions
Frequently Asked Questions
Can I really do this myself, or should a shop apply it?
If you can paint a fence, you can coat a camper roof. The product is single-component — no mixing — and applies by brush and roller. A shop makes sense if your roof has soft spots or delamination that need repair first, or if you simply want a warranty-backed installation. Either way it is the same three-step system.
How much do I need for my camper?
Plan on 80 square feet per gallon per coat, two coats, plus about 10% extra for detail work on seams and vents. A 8x24 roof (192 sq ft) needs roughly 5 gallons of Coat, 1 gallon of Prime, and one bottle of Wash concentrate.
How long before it can take rain?
Dry to touch in 2–3 hours at 70°F and rain-safe in about 4. It is walkable in 24 hours and reaches full cure in 7 days. Cooler temperatures stretch all of these times.
Does it work on my roof type?
Yes on EPDM rubber, TPO, fiberglass, and painted aluminum — the wash and primer steps are what make each of those surfaces bondable. The one surface we tell people to skip is a roof previously coated with silicone; nothing bonds to silicone except more silicone.
How long does the membrane last?
Expect 10+ years on a roof that gets the full three-step prep, with a simple recoat — wash and one fresh coat, no stripping — extending it from there. The system is designed to be renewed, not replaced.
Can I apply it in cold weather?
Apply between 50°F and 95°F with the roof dry and no rain or dew expected before it skins over. Below 50°F cure slows dramatically and adhesion suffers. In shoulder seasons, start mid-morning so the film skins before the evening dew.
