Fuchoi Liquid RV Roof Coating — 1 Gallon White Elastomeric Waterproof Sealant, UV-Reflective Durability

Fuchoi Liquid RV Roof Coating is a one-gallon, white elastomeric sealant that creates a durable, UV-reflective waterproof membrane to stop leaks and protect camper roofs.

Designed for RV owners and DIY repairers, this professional-grade liquid rubber coats flat and low-slope roofs to prevent ponding water, block UV damage, and slow oxidation. The formulation bonds to common roof materials—EPDM, TPO, fiberglass, metal, and more—flexing with roof movement to reduce cracking. It comes as a complete kit with application tools so you can mix, apply, and cure a protective layer in a single session.

How fast does this RV roof coating dry and how many square feet will one gallon cover?

The coating sets quickly and can be used as a single heavy layer or multiple thinner layers; drying time and coverage depend on ambient conditions and film thickness.

• Cures to a rubbery membrane; allow 4–8 hours between coats when adding layers.
• One recommended thick coat (1–2 mm dry film) covers up to about 50 sq. ft.
• Temperature and humidity affect cure speed—warmer, drier weather reduces drying time.

Will it adhere to my camper’s existing roof material?

This elastomeric formula is engineered to bond with a range of roof substrates and accommodate movement without cracking.

• Compatible with EPDM, TPO, fiberglass, painted metal, wood, and aged rubber.
• No primer typically required for many surfaces—cleaning and sanding improve adhesion.
• Anti-corrosion additives help protect metal roofs from rust and chemical exposure.

How does the coating help with heat and weather exposure?

The bright white finish reflects sunlight and resists weathering, which helps reduce interior heat gain and slows surface degradation.

• Reflective white surface lowers roof surface temperature compared with darker coatings.
• Formulated to resist oxidation and fading so the membrane stays intact season after season.
• Flexible elastomeric layer prevents small splits from enlarging during temperature swings.

What tools and prep are included, and how hard is the application?

The product ships with a practical kit to make a single-person application straightforward for common repairs or full roof recoats.

• Included: nitrile gloves (×2), paint roller (×1), brush (×1), masking film, tape, and sandpaper (×2).
• Prep requires cleaning, removing loose material, and light sanding for best results.
• Apply by roller or brush in even passes; no special equipment is necessary for typical jobs.
