Dicor EPDM Roof Cleaner & Activator, 1 Quart — Fast-Drying, Non-Petroleum

Dicor RP-CRP-Q is a commercial-grade EPDM cleaner/activator in a 1-quart size that prepares rubber RV roofs for maximum adhesion of Dicor acrylic roof coating.

If you're planning to rejuvenate an RV roof made from EPDM rubber, proper surface prep is the most important step. This product is Part 1 of Dicor's two-part roof coating system: a fast-drying cleaner and activator formulated to remove contaminants and condition EPDM so the acrylic coating will bond uniformly. Use it as instructed—spray on, rinse thoroughly—and you can coat over previously soiled rubber membranes to help extend the roof's useful life and restore appearance.

How does this cleaner/activator get an EPDM roof ready for coating?

Dicor RP-CRP-Q works by loosening and removing dirt, oils, and oxidation left on EPDM surfaces so the acrylic topcoat can stick properly. It’s designed specifically for rubber roofs; its chemistry avoids harsh abrasives and petroleum distillates that can damage the membrane. After application and rinsing, the surface will be clean and primed for immediate coating.

• Spray-on, rinse-off application simplifies prep.
• Formulated to work over EPDM with light residual impurities.
• Contains no petroleum distillates, harsh abrasives, or citric ingredients.
• Quick drying to speed up overall project time.

What coverage and labor savings can I expect from the 1-quart container?

One quart treats approximately 125 square feet of EPDM surface, making it suitable for spot work or smaller RV roofs. Dicor advertises labor savings versus competing systems because the cleaner/activator reduces scrubbing and repeat prep, letting you move to the coating step faster.

• Coverage: roughly 1 quart per 125 sq. ft.
• Less manual abrasion needed compared with some alternatives.
• Quicker turnaround from prep to coating thanks to fast drying.

Are there surfaces I should protect when using this product?

This formulation is intended only for EPDM rubber roofing and can harm vinyl, painted surfaces, plastics, and trim if it contacts them. Take precautions: mask, tape, and cover nearby sidewalls, end caps, windows, and other exterior trim to prevent accidental exposure during spraying and rinsing.

• Not for use on non-EPDM exterior components—may cause damage.
• Cover sidewalls, end caps, and trim with plastic sheeting before application.
• Rinse areas promptly if overspray occurs.

How does this part fit into Dicor's two-part roof coating process?

This cleaner/activator is the preparatory first step: remove contaminants, activate the rubber surface, and allow it to dry. Once the EPDM is prepared, apply Dicor's acrylic roof coating (Part 2) for a protective, weather-resistant layer that improves appearance and shields the membrane. Proper prep is essential for adhesion and coating performance.

• Step 1: Clean and activate EPDM with RP-CRP-Q; rinse thoroughly.
• Step 2: Let surface dry completely before applying Dicor acrylic coating.
• Follow manufacturer instructions for best adhesion and coverage.

Who is this for: RV owners, mobile-home technicians, and professional roof maintenance teams working with EPDM rubber membranes who need a purpose-built preparatory product. It’s meant for anyone planning to apply Dicor acrylic roof coating or similar coatings over EPDM and who wants a reliable, quick-drying cleaner that minimizes abrasive labor. Not recommended for general exterior cleaning or for surfaces other than EPDM rubber.
