Liquid Rubber Waterproof Sealant – 1 Gallon
The Liquid Rubber Waterproof Sealant uses an industrial-strength bitumen formula to form a seamless protective membrane on flat roofs, metal roofs, foundations, and more. It is designed for long-lasting flexibility, with elongation over 950%, helping the coating move with the structure and temperature changes without cracking. This makes it a strong choice for buildings that experience seasonal movement or UV exposure. Best for property owners seeking a single-coat or multi-application sealant that can bridge minor cracks and provide a durable water barrier.
Best for: flat or low-slope roofs and vertical surfaces that require a robust, flexible seal. It also serves foundations and gutters where water intrusion is a concern. Caution: for vertical applications, the listed coverage requires multiple heavy coats to achieve a 60-80 mil membrane, which may require more material and time.
Liquid Rubber RV Roof Sealant – 1 Gallon
This professional-grade RV roof sealant delivers a flexible, solar-reflective waterproof membrane suitable for EPDM, TPO, fiberglass, and aluminum surfaces on campers and travel trailers. The product is designed to reduce interior heat through heat-reflective properties while extending roof life. It works as part of a complete RV roof sealing system and pairs with primers for enhanced adhesion. Best for: RV owners seeking a durable, year-round seal with reflected heat reduction. Limitation: compatibility notes suggest primer may be needed for optimal adhesion on some surfaces.
Liquid Rubber EPDM and TPO Primer – 1 Gallon
EPDM Primer is a water-based rubber polymer primer designed to boost adhesion on EPDM surfaces before applying the RV roof coating. It supports RV roof maintenance programs by improving bonding and weather resistance. Best for: owners performing routine RV roof upkeep who want a strong basecoat for better coating performance. Caution: ensure surfaces are clean and dry before applying to maximize adhesion and cure outcomes.
Liquid Rubber RV Roof Coating 30 Ft Kit
This 30 Ft leak repair kit provides a complete system for RV roofs, including sealer, EPDM primer, cleaner, seam tape, and lap sealant. The coating is tailored for flexible, solar-reflective membranes that endure temperature shifts without cracking. Best for: RV owners seeking an all-in-one solution that covers sealing, priming, and edge protection in one purchase. Limitation: kit contents may require additional brushes or rollers depending on application size.
Liquid Rubber Geo-Textile – 4 Inch x 160 Foot Roll
Geo-Textile combines stitch-bonded polyester fabric with Liquid Rubber to reinforce and bridge gaps in roofing joints, seams, and vents. It’s a practical solution for bridging plys and creating multi-seal layers on complex roof shapes or large flat areas. Best for: projects needing reinforced seams and elongated seals where fabric support adds strength. Limitation: requires careful handling to prevent wrinkling and ensure even coating along long seams.
Liquid Rubber Color Roof Sealant – 1 Gallon
Color Roof Sealant is a waterproof elastomeric coating designed for flat, low-slope, and metal roofs, forming a seamless, flexible membrane that resists weathering and UV exposure. It cures into a durable rubber-like layer with up to 900% elongation, allowing movement without cracking. Best for: roofs requiring a color finish and durable waterproofing. Caution: full cure times can vary with temperatures and humidity; multiple heavy coats are often needed to achieve a complete membrane.
Buying Guide: Practical Considerations for Liquid Rubber Roofing Supplies
What roofing material is most compatible?
Most Liquid Rubber products target EPDM, TPO, fiberglass, metal, and concrete surfaces. Primers improve adhesion on EPDM surfaces, while coatings are formulated to work across multiple substrates. Always confirm compatibility with your roof material before application.
How to choose based on climate?
For hot climates, look for solar-reflective or UV-stable formulas to reduce heat absorption. In cold or variable climates, prioritize high elongation to accommodate movement without cracking. Proper surface preparation is essential in both cases.
What application method works best?
Most products can be brushed, rolled, or sprayed. For large flat areas, spray applications can speed up the process, but require appropriate equipment and masking. For vertical surfaces, heavier coats may be necessary to achieve the desired membrane thickness.
Do you need primers or accessories?
EPDM surfaces often benefit from a dedicated primer to boost adhesion. Some RV roof kits include sealer, seam tape, and lap sealant, offering a complete system. Review kit contents to determine if additional tools are required for your project.
How should you manage cure times and maintenance?
Drying and curing times vary with temperature, humidity, and coat thickness. Plan projects to avoid rain during cure windows. Regular inspection after installation helps identify early signs of cracking or adhesion loss, enabling timely maintenance.
FAQ: Quick Answers for Buyers
- Q: Is liquid rubber suitable for metal roofs?
- A: Yes, many formulas are designed for metal roofs and provide flexible, UV-stable protection. Check product specifics for metal compatibility and required coatings.
- Q: Do I need a primer on EPDM roof surfaces?
- A: Primers improve adhesion on EPDM; using them can extend the life of the coating, especially on older or smoother EPDM surfaces.
- Q: How many coats are required?
- A: Most products require multiple heavy coats to reach the recommended membrane thickness. Follow manufacturer guidelines for coverage per coat.
- Q: Can these coatings be used on RV awnings or vents?
- A: Yes, many formulas cover vents, skylights, and awning components as part of a complete roof sealing system, but verify surface compatibility first.
- Q: Do these products cure in UV light?
- A: Many formulations are UV-stable, but some wax or colorant layers may influence long-term appearance. Check product details for UV performance notes.
