Wadities RV Roof Coating White — 1 Gallon Solar-Reflective Waterproof Sealant, Flexible UV-Stable Membrane

Wadities RV Roof Coating is a white, solar-reflective, flexible waterproof sealant designed to restore and protect camper, trailer, motorhome and metal building roofs.

This one-gallon product forms a durable, UV-stable membrane that helps reduce roof temperature, fill cracks and seal leaks when applied in heavy coats. Formulated with a higher solids content than thin paints, it’s intended for users who want a long-lasting protective layer that tolerates movement and resists sun degradation. The coating can be brushed, rolled or sprayed and covers roughly 50 sq ft per gallon at a 1-gallon-per-50-sq-ft final thickness, so plan for multiple coats on older or damaged roofs.

How does this coating keep my RV cooler in hot weather?

The bright white, solar-reflective finish bounces back a portion of sunlight and heat, reducing solar gain on the roof surface. While not a substitute for active cooling systems, lowering roof temperature can ease strain on air conditioners and interior heat buildup. UV-stable components also slow sun-driven breakdown of roofing materials.

• High-reflectance white finish reduces rooftop heat absorption.
• UV-stable formula resists sun-driven deterioration.
• Helps reduce thermal stress that causes cracks and splits.

What surfaces can I use Wadities roof sealant on?

This coating is formulated for a wide range of outdoor surfaces commonly found on campers and buildings. It adheres to EPDM, TPO, metal, fiberglass and many roofing substrates after proper surface prep. It’s also suitable for other projects like gutters, planters or concrete patches where a waterproof, flexible layer is needed.

• Compatible with metal roofs, trailers, RVs and motorhomes.
• Works on flat roof sections, gutters, concrete, wood and stucco.
• Not intended for submerged applications or surfaces with active leaks without prep.

How do I apply the coating for best results?

Application is similar to painting: brush, roller or use a high-quality spray. Apply heavy coats and build up the membrane in 2–3 passes for a reliable waterproof layer; one gallon should yield a final thickness at the recommended 50 sq ft coverage per gallon. Allow proper cure time between coats and ensure the roof is clean, dry and free of loose material before starting.

• Clean and dry surface; remove loose material and rust.
• Apply 2–3 heavy coats; mix before use and between coats.
• Brush, roller, or professional-grade paint sprayer acceptable.

What level of flexibility and durability does this product offer?

Wadities is formulated to remain flexible after curing, accommodating movement and thermal expansion without cracking. The manufacturer cites a high degree of elongation to reduce adhesion failure and maintain a continuous waterproof membrane. This flexibility is useful on boats, trailers and buildings that experience shifting or vibration.

• Designed to maintain flexibility and membrane integrity.
• Higher solids concentration for a thicker, more protective layer.
• UV-resistant to minimize breakdown from sun exposure.

Who is this for: This 1-gallon Wadities coating suits DIYers, RV owners, property managers and contractors seeking an economical way to extend the life of roofs and waterproof outdoor surfaces. It’s best for users who can do basic surface preparation and apply multiple coats; choose professional help for extensive structural damage or active, pressurized leaks. Keep in mind coverage estimates—large RVs or complete metal buildings may require multiple gallons for full protection.
