First Impressions of Dicor 533RM-12 EPDM Rubber Roof Repair Membrane 12in x 25′ Roll
The Dicor 533RM-12 EPDM Rubber Roof Repair Membrane 12in x 25′ Roll promises a simple, effective solution for repairing EPDM rubber roofs commonly found on RVs, campers, and even some homes. Dicor is a well-known name in the RV and camper industry, so I was eager to see if their repair membrane lived up to their reputation. It claims to be resistant to tearing and abrasion, and tolerant of temperature extremes, offering superior water resistance.
What prompted me to seek out this product was a small but persistent leak that developed around the vent on my vintage Airstream camper. I tried patching it with conventional sealant, but the expansion and contraction of the metal and rubber, combined with UV exposure, kept breaking the seal. This Dicor membrane seemed like a more permanent solution, offering a flexible and durable barrier.
Upon unboxing, the roll felt substantial and well-made. The EPDM rubber had a slight texture and seemed pliable enough to conform to the curved surface of my Airstream roof. I was pleased to find that there was no noticeable odor, indicating the absence of harsh solvents or VOCs, as advertised.
I considered using a competitor’s self-adhesive membrane, but many of those options contained asphalt and solvents, which I was trying to avoid due to environmental concerns and potential long-term degradation. The Dicor 533RM-12 stood out because of its environmentally friendly composition, its compatibility with EPDM rubber, and the Dicor brand’s solid reputation. I was cautiously optimistic, hoping it would be the long-term fix I needed.
Real-World Testing: Putting Dicor 533RM-12 EPDM Rubber Roof Repair Membrane 12in x 25′ Roll to the Test
First Use Experience
My first test involved repairing the leaky vent on my Airstream. I thoroughly cleaned the existing EPDM roof around the vent with a specialized rubber roof cleaner to ensure proper adhesion. Using a utility knife, I cut a piece of the Dicor 533RM-12 membrane slightly larger than the damaged area, and carefully applied it, pressing firmly to create a strong bond.
The application went smoothly, even with the slightly uneven surface around the vent. The membrane was pliable and conformed well. We had a rainstorm later that week, and I’m happy to report no leaks!
Extended Use & Reliability
Several months have passed since the initial application, and the Dicor 533RM-12 membrane is holding up remarkably well. There are no signs of peeling, cracking, or bubbling, even after enduring intense summer heat and heavy thunderstorms. The membrane has maintained its flexibility and continues to provide a watertight seal.
Maintaining the repaired area is straightforward. A simple wash with soap and water keeps the surface clean, and there’s no need for any special treatments or sealants. Compared to my previous attempts with traditional sealants, the Dicor membrane is a clear winner in terms of durability and long-term performance.
