Dicor EPDM Roof Cleaner/Activator Quart — 1 qt prep for acrylic coatings, fast-drying coverage ~125 sq ft

Dicor RP-CRP-Q EPDM Cleaner/Activator is a one-quart preparatory solution that cleans and activates rubber RV roofs so acrylic roof coatings adhere evenly and last longer.

Whether you’re refreshing an aging RV roof or preparing new EPDM for recoating, this Part 1 cleaner/activator is formulated to remove surface contaminants and improve bonding for the two-part Dicor coating system. Fast-drying and designed specifically for EPDM rubber membranes, it helps ensure the acrylic topcoat forms a consistent, protective film that resists weathering. Use caution to protect non-rubber exterior parts—this product is concentrated for rubber surfaces only.

How does this cleaner/activator prepare EPDM for an acrylic coating?

The formula lifts dirt, oils, and light residual contaminants while chemically conditioning the EPDM surface for stronger mechanical and chemical adhesion. It’s intended as the first step of Dicor’s two-part system so the acrylic coating can bond uniformly.

• Spray-on application that penetrates surface films
• Quick rinse-off to remove loosened debris
• Leaves a receptive surface for acrylic coatings
• Compatible with residual impurities on EPDM

What coverage and drying performance should I expect?

One quart covers approximately 125 square feet when applied as directed, making it suitable for spot preparation or smaller roof areas. The product is formulated to dry quickly so you can complete surface prep and move to coating without long delays.

• Coverage: ~1 qt per 125 sq ft under typical conditions
• Fast drying to accelerate project workflow
• Ideal for prep work before applying Dicor acrylic topcoat

Are there safety or surface protection considerations?

This cleaner/activator is designed specifically for EPDM rubber and can harm non-rubber exterior parts such as painted surfaces, plastics, or trim. Protect adjacent areas thoroughly before use and follow label directions for safe application and rinsing.

• Not for use on painted or plastic surfaces without protection
• Recommend sheeting over sidewalls and end caps during application
• Rinse thoroughly after use to remove residues

How does this product fit into a complete roof restoration workflow?

Use Dicor RP-CRP-Q as the initial treatment to clean and activate the EPDM membrane, then allow the surface to dry before applying the Dicor acrylic coating. This two-step approach helps restore appearance and extend service life without extensive tear-off.

• Step 1: Clean/activate EPDM with this product
• Step 2: Apply Dicor acrylic coating per manufacturer instructions
• Saves labor time versus more invasive repair methods

Who is this for: RV owners, maintenance professionals, and DIYers who want a targeted, manufacturer-recommended surface preparation for EPDM rubber roofs. It’s best for projects where preserving the existing membrane and improving coating adhesion are priorities, and for anyone comfortable protecting non-rubber exterior parts during application.
