Dicor Seal-Tite is a flexible, weather-resistant white repair tape designed to permanently seal leaks and gaps on RV roofs and many other surfaces. Dicor Seal-Tite combines a durable vinyl surface with a tacky, weatherproof backing so you can quickly patch and seal problem areas on TPO, EPDM, PVC, fiberglass, metal, wood, and plastics. The roll is 4 inches wide and 12.5 feet long, sized for roof seams, vent boots, flashings, and trim repairs; it lays flat, conforms to contours, and cures to form a long-lasting barrier against water intrusion.

What surfaces will this repair tape stick to reliably?

Seal-Tite is formulated to adhere to a wide range of common roofing and RV materials. It bonds to smooth and slightly textured surfaces and remains flexible with temperature changes, reducing peel and lift over time.

• EPDM rubber and TPO roofing membranes
• PVC roofing, fiberglass panels, and painted metal
• Wood trim, plastics, aluminum, and steel

How quickly does Seal-Tite stop leaks and become weatherproof?

The tape produces an immediate mechanical seal on application to stop active leaks. Within 24 hours the material fully resolves as it conforms and adheres under typical conditions, providing a robust waterproof barrier for ongoing protection.

• Stops most leaks on contact for immediate protection
• Settles and completes bonding within 24 hours
• Maintains flexibility after curing to tolerate movement

How do I apply the 4" x 12.5' roll for a lasting repair?

Clean and dry the repair area, remove any loose debris, and peel the backing as you press the tape firmly into place. Use a roller or hand pressure to smooth out air pockets and ensure full contact along edges and curves.

• Surface prep: remove dirt, oil, and loose material
• Lay tape centered over seam or hole, press firmly
• Trim excess and overlap edges for longer seams

Will the white color match my RV and remain durable?

The white finish is chosen to blend with many RV roofs and trim, reflecting sunlight to help reduce heat absorption. The vinyl face resists weathering and maintains appearance while the adhesive backing protects the repaired area from water and UV exposure.

• White hue for a clean, discreet look on light roofs
• UV-resistant surface helps reduce discoloration
• Durable vinyl resists cracking and fading over time
