Dicor Self-Fusing Repair Tape

Dicor Self-Fusing Repair Tape: Purpose-Built for RV Roof Defense

When a leak appears on an RV roof, the clock starts ticking. Water intrusion can compromise decking, insulation, and interior finishes faster than most owners expect. That is why Dicor has engineered a focused lineup of self-fusing repair tapes designed specifically for the stresses that RV, trailer, and motorhome roofs endure — UV exposure, thermal cycling, vibration, and the relentless expansion and contraction of life on the road.

Dicor's reputation in RV roofing is hard-earned. Dicor Corporation has been a leading supplier of component products to RV manufacturers and other industries since 1984, and it has become the leading supplier of roofing repair and care products in the RV aftermarket. That depth of experience is evident in every roll of self-fusing tape the brand produces.

The DiSeal Line: Gray Matter™ Adhesive Technology

The flagship product in Dicor's repair tape family is the DiSeal Patch Sealing Tape. Available in both TPO and Aluminum versions, DiSeal is a water-resistant sealing tape that utilizes Dicor's proprietary Gray Matter™ adhesive technology for an aggressive grip and superior adhesion. The formula is engineered to stay flexible — it will not crack, peel, or harden over time, which is critical for surfaces that constantly move and flex. DiSeal delivers maximum durability and UV protection, and is proven for exterior use on roofs, sidewalls, holding tanks, and more. Application is a simple peel-and-stick process, making it accessible for DIY repairs without sacrificing performance.

DiSeal is compatible with a wide range of roofing substrates — EPDM rubber, TPO, PVC, fiberglass, and metal — making it a versatile choice regardless of what your RV roof is made from.

EPDM Rubber Roof Repair Membrane

For larger tears, punctures, or breaks in rubber and fiberglass roofs, Dicor offers its EPDM Rubber Roof Repair Membrane, a self-adhering sheet that conforms to most shapes and surfaces. It repairs punctures, tears, and breaks in rubber, metal, and fiberglass roofs with the same easy peel-and-stick application philosophy. Available in roll formats, this membrane is ideal when a patch-style repair is needed over a wider damaged area.

Patchit™ Roof Repair Kit

Dicor also offers the Patchit™ Roof Repair Kit, a convenient all-in-one solution for RV owners who want a ready-to-go repair package. It brings together Dicor's repair tape technology in a kit form, simplifying the process of addressing unexpected roof damage whether at home or on the road.
