Dicor Acrylic Elastomeric RV Roof Coating — Arctic White 1 Gallon, Flexible, Reflective

Dicor RP-MRC-1 is a 100% acrylic elastomeric roof coating designed to protect and reflect on metal RV roofs, sold in a 1‑gallon Arctic white can.

This single‑component coating is formulated specifically for metal RV roofing (aluminum, galvanized steel, and pre‑coated metal) to deliver a flexible, rubber‑like membrane that moves with the roof. Its bright Arctic white finish increases solar reflectivity to reduce heat gain inside the coach. Dicor recommends two coats at an application rate of approximately 1 gallon per 200 sq. ft. per coat for proper protection and coverage.

How does this coating protect a metal RV roof?

The acrylic elastomeric resin cures into a continuous, elastic layer that bridges small surface imperfections and accommodates thermal movement. It resists cracking as the roof expands and contracts, helping maintain a sealed surface that sheds water and shields the underlying metal from weather exposure.

• Forms a flexible, rubber‑like membrane that expands and contracts with the roof
• Seals minor surface imperfections and helps shed water
• Suitable for aluminum, steel, and previously coated metal RV roofs

Will it help keep my RV interior cooler?

Yes — the Arctic white pigment is chosen for high reflectivity, which reduces solar heat absorption on the roof surface. By reflecting more sunlight, the coating can lower roof temperatures and reduce the cooling load inside the RV on sunny days.

• Brilliant white finish increases solar reflectivity
• Can reduce roof surface temperature under direct sun
• Works best when applied evenly in the recommended two‑coat system

How do I apply Dicor RP‑MRC‑1 and what coverage should I expect?

Apply to a clean, dry metal roof that is free of loose coatings, dirt, oil, and oxidation. Dicor recommends two full coats; plan on roughly 1 gallon covering 200 sq. ft. per coat, so one gallon will cover about 100 sq. ft. when following the two‑coat guideline.

• Surface must be clean, dry, and sound before coating
• Apply two coats for recommended protection and reflectivity
• Application rate: ~1 gallon per 200 sq. ft. per coat (two coats needed)

Is this compatible with all RV roof materials?

This product is formulated for metal RV roofs only and is not recommended for EPDM rubber, TPO, or other single‑ply membrane roofing. Using it on incompatible substrates can lead to poor adhesion and performance issues.

• Intended for metal, aluminum, steel, and previously coated metal roofs
• Not recommended for EPDM rubber or TPO roofing
• Test small areas when in doubt about previous coatings

Who is this for: Dicor RP‑MRC‑1 is aimed at RV owners, maintenance technicians, and DIYers who want a purpose‑built acrylic elastomeric coating to protect and brighten metal roofs. If you own an aluminum, galvanized, or previously coated metal RV roof and are looking to extend its service life while improving reflectivity, this 1‑gallon Arctic white formulation provides a contractor‑grade option—just be sure the roof substrate is metal and allow for two coats at the recommended coverage rate.
