FAQ
RV Sealing, Answered
DIY or have a service center do it?
A towable with a walkable roof is a realistic owner project — no mixing, brush-and-roll application. A 35-foot Class A with a curved fiberglass roof and four slides is a spray job with real ladder logistics; that is service-center territory. Same product either way, so nothing is wasted if you start DIY and hand off.
Do slide-out roofs really need coating if I have toppers?
Yes. Toppers shed rain but trap condensation and admit wind-blown water at the ends. The slide deck is low-slope bare metal or membrane that ponds water — five extra square feet of coating now beats a slide-floor rebuild later.
How much product does a whole rig take?
Figure the roof at 70–90 sq ft per gallon per coat, two coats, then add roughly 15% for caps, slide roofs, and details. A 32-foot rig with two slides typically lands at 8–9 gallons total. Send dimensions and we will do the math for you.
How soon can I drive after coating?
Rain-safe in about 4 hours, but give it 24 hours before highway speeds — 70 mph wind load is a harsher test than a thunderstorm. Full cure is 7 days; avoid dragging ladders or mounting hardware on the roof that first week.
My roof is fiberglass and gelcoat is chalking. Same process?
Yes, with prep emphasis: wash to bare, sound gelcoat, prime, then coat. Fiberglass takes the membrane beautifully once the chalk is gone — skipping the primer on chalked gelcoat is the #1 cause of adhesion failure we see.
Can it be applied in cold weather?
Hold for 50°F and rising with a dry surface and no dew before skin-over. In the North that means roughly April through October. Service centers with heated bays coat year-round — one more reason the program exists.
