Dicor Acrylic Elastomeric RV Roof Coating 1 Gallon - Reflective White

In this review of the Dicor acrylic elastomeric coating, the bottom line is simple: this is a straightforward, budget-friendly option for RV owners with metal roofs who want a reflective, protective finish. It is aimed at DIYers and maintenance-minded owners who need a product that adheres to metal, aluminum, or previously coated surfaces and helps lower interior temperatures thanks to a brilliant white finish. The coating's elastomeric formula expands and contracts with roof movement, and when applied correctly in two coats it provides a bright, protective layer suited to seasonal exposure.

Key Features

• Metal compatibility: Formulated specifically for metal RV roofing, it bonds to aluminum, steel and previously coated surfaces for a consistent finish.
• Temperature regulating color: The arctic white hue offers superior reflectivity to help reduce heat buildup inside the RV on sunny days.
• Elastomeric performance: Made with 100% acrylic elastomeric resins to stretch and contract with roof movement, reducing stress cracks.
• Coverage per coat: Requires two coats applied at about 1 gallon per 200 sq. ft. per coat to achieve effective protection.
• Appearance: Provides a clean, bright white finish that can refresh the look of an older metal or previously coated RV roof.

Who It's For

This coating is best for RV owners and maintenance-minded DIYers who have metal, aluminum, or already coated RV roofs and want a reflective, protective topcoat that is simple to roll or brush on. It works well for people looking to reduce interior heat and improve roof appearance without professional application.

It is not for owners of EPDM rubber or TPO roofs, and those with fabric or non-metal surfaces should look for a product formulated for those substrates. If long-term adhesion in all climates is the primary concern, some users report mixed durability and may prefer a professional-grade or specialty system.

Pros & Cons

Pros

• Bright reflective white helps lower interior temperatures on hot days.
• Elastomeric acrylic formula expands and contracts with the roof to reduce stress.
• Easy to apply for a DIYer and refreshes the look of older metal roofs.
• Suitable for aluminum, steel and previously coated RV roofs.

Cons

• Not recommended for EPDM rubber or TPO roofing, limiting substrate compatibility.
• Some customers report mixed durability or peeling in certain conditions, so surface prep and proper application are critical.

Our Verdict
