Liquid Rubber RV Roof Sealant – 1 Gallon
The 1-gallon Liquid Rubber RV Roof Sealant delivers a flexible waterproof membrane designed to seal and protect EPDM, TPO, fiberglass, and aluminum roofs. Its elastomeric formula accommodates temperature changes without cracking, helping to keep interiors dry year-round. The product supports a complete roof protection system with heat reflectivity to reduce interior temperatures and energy use. It works well with Liquid Rubber EPDM Primer for stronger adhesion on EPDM and TPO surfaces, offering durable, leak-proof coverage across various RV roof components.
Liquid Rubber RV Roof Sealant – 5 Gallon
The 5-gallon variant provides the same flexible, waterproof membrane with exceptional solar reflectivity, extended to larger roof areas. Built to pair with EPDM, TPO, fiberglass, and aluminum roofs, it helps maintain interior comfort by reducing heat buildup. This size is ideal for bigger travel trailers or motorhomes and supports a durable roof sealing system designed to resist leaks and weather stresses. When used with the corresponding primer, adhesion on challenging surfaces is enhanced, ensuring long-term performance.
Liquid Rubber EPDM and TPO Primer – 1 Gallon
EPDM and TPO primer is a water-based rubber polymer designed to boost adhesion on EPDM surfaces before applying the RV roof coating. This primer supports weatherproofing of RV roofs and other EPDM rubber surfaces, with application methods suitable for brushes, rollers, or spray equipment. Proper priming improves bond strength and ensures the coating adheres across the roof’s irregularities, increasing overall longevity and reducing maintenance needs.
BEEST RV Roof Repair Kit
The BEEST kit offers a complete solution for EPDM or TPO roofs, including a 5-gallon coating, 1 gallon of EPDM primer, 32 oz cleaner, two sealants, a seam roller, seam tape, and gloves. This bundle is designed to refresh and seal RV roofs while providing tools to ensure proper seam and surface preparation. It is rated for temperature reduction and is intended to deliver improved adhesion and longevity through an integrated system approach, making it convenient for full roof restoration projects.
Kohree RV Roof Coating 1 Gallon
Kohree’s 1-gallon silicone-based roof coating provides 100% silicone protection with no primer required. It yields a flexible, waterproof seal on EPDM, TPO, metal, wood, and fiberglass roofs. The white coating reflects sunlight to reduce heat absorption and interior temperatures, and its easy-to-apply formula works with brushes, rollers, or sprayers. Coverage guidance suggests two to three thicker coats for optimal durability, making it a practical choice for mid-size to smaller RV roofs.
Buying Guide: Key Purchase Considerations
When choosing an RV roof coating for TPO or EPDM, consider the following factors:
- Material compatibility: Confirm the coating works with your roof substrate (EPDM, TPO, fiberglass, aluminum).
- Solar reflectivity: A reflective coating helps reduce interior temperatures and energy costs on hot days.
- Adhesion and primers: Some surfaces benefit from a dedicated primer to improve bond strength and longevity.
- Application method: Brushes, rollers, or compatible sprayers affect labor time and coating thickness.
- Coverage and coats: Larger roofs may require higher-volume products; plan for multiple coats where indicated.
- Durability and flexibility: A flexible membrane resists cracking under temperature fluctuations and movement.
- Kit inclusions: All-in-one kits can simplify installation but verify contents match your needs and roof size.
- VOC and safety: Check product safety data and ensure proper ventilation during application and curing.
In selecting among the options, users should balance roof size, substrate, climate, and desired maintenance level. For larger RVs, a 5-gallon coating paired with a compatible primer often provides better value and fewer reapplications. For quicker touch-ups or smaller roofs, a 1-gallon or silicone-based product can deliver reliable results with straightforward application. Regardless of choice, following proper surface preparation and curing times is essential to maximize performance and roof longevity.
