Ideal for RV roofs and other rubber membranes, it ensures a waterproof, durable bond for subsequent coatings and seam tapes. Fast curing and easy to apply with brush, roller, or spray, this primer is a must-have for professional-grade weatherproofing and roof maintenance. ## Description Liquid Rubber EPDM Primer is a rubber polymer water based roofing primer, and like its name; its been specifically designed for EPDM surfaces. EPDM Rubber is extremely hard to stick to without a quality Primer. This Primer does not react with atmospheric moisture allowing it to be opened and resealed for use at a later date. Surface Preparation All work surfaces should be clean and dry. Clean the surface with Liquid Rubber RV Smart Cleaner; rinse, allow to dry, and wipe down with acetone prior to applying the EPDM primer (a degreaser may be necessary). Do not use as a membrane cleaner; not to be used on TPO or PVC roof membranes. Do not apply later in the day if rain or dew is forecast and install above 10C (50F) and rising. Storage: Store material in original unopened containers at temperatures between 40F - 90F/4C - 32C. ## Features - WHY EPDM PRIMER - EPDM Primer is a rubber polymer water-based roofing primer, designed for increasing adhesion on EPDM surfaces. - RV ROOFING MAINTENANCE - Weatherproof RV roofs and other EPDM rubber surfaces by first applying this EPDM Primer before applying the RV Roof Coating - EASY TO APPLY - Apply using a conventional brush or roller equipment; may also be sprayed using a delivery system and nozzles appropriate for this material - APPLICATION - All surfaces should be clean, dry, and free of anything that may result in a surface that is uneven or not sound - FOR A BULLETPROOF SYSTEM - Liquid rubber RV Smart Cleaner before Primer application; EPDM Primer improves adhesion for Liquid rubber RV Roof Coating - WHY EPDM PRIMER - EPDM Primer is a rubber polymer water-based roofing primer, designed for adhesion bonding on EPDM surfaces - RV ROOFING MAINTENANCE - Weatherproof RV roofs and other EPDM rubber surfaces by first applying this EPDM Primer before applying the actual waterproof sealant or seam tape - APPLICATION - All surfaces should be clean, dry, and free of contaminants that may result in a surface that is uneven or not sound - FOR A BULLETPROOF SYSTEM - Liquid rubber RV Smart Cleaner before Primer application; EPDM Primer improves adhesion for Seam Tape and other Liquid rubber RV Roof Coating - Packaging may vary ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TYPPLD9 | | ASIN | B07TYPPLD9 | | Age Range Description | Adult | | Best Sellers Rank | #136,591 in Automotive ( See Top 100 in Automotive ) #38 in RV Cleaning, Storage & Maintenance | | Brand Name | Liquid Rubber | | Container Type | Can | | Coverage | Medium | | Customer Reviews | 4.1 4.1 out of 5 stars (249) | | Customer reviews | 4.1 4.1 out of 5 stars (249) | | Date First Available | 20 January 2024 | | Dry Time In Hours | 24 | | Finish Type | Gloss | | Full Cure Time | 0.5 Hours | | Included Components | Brush, Roller, Liquid rubber RV Smart Cleaner | | Indoor Outdoor Usage | Outdoor | | Is Waterproof | True | | Item Form | Liquid | | Item Volume | 1 Quarts | | Item model number | 89600 | | Model Number | 89600 | | Package Dimensions | 12.8 x 12.6 x 12.4 cm; 980 g | | Paint Type | liquid | | Part Number | 89600 | | Size | 1 | | Special Features | Waterproof | | Specific Uses For Product | EPDM surfaces, Rubber roofs, Pond liners | | Surface Recommendation | roof | | UPC | 628421896004 | | Unit Count | 32.0 Fluid Ounces | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Liquid Rubber - **Finish type:** Gloss - **Item volume:** 1 Quarts - **Size:** 1 - **Special features:** Waterproof ## Images ![EPDM Rubber and RV Roof Primer - Weatherseal Camper and Trailer Roofing Coating 1 Quart - Image 1](https://m.media-amazon.com/images/I/71kQ0uXf5kL.jpg) ## Questions & Answers **Q: will this adhere to a roof that has been coated with fiber filled aluminized roofing?** A: EPDM Primer would not be needed for that type of roofing. Bonding to your existing material will depend on which product you want to apply and whether the existing coating is water-based or solvenated. Please reach out to us to discuss your project in greater detail. Liquid Rubber USA/CAN has great technical support, application info and instructional video's. Have a great day! **Q: How long before you can apply the liquid rubber?** A: wait for 2 hours **Q: Very tacky, tip for recoat roof?** A: You can work in manageable sections or from the side off a ladder or scaffold. A popular method is to primer one half down the middle and work from the bare side. once you apply the first coat of RV coating and it dries, the surface will be tack free and you can walk on it to prime and coat the other half. Just leave a little primer exposed from the first half so you can marry to the other side. **Q: How much would I need for a 40 foot goose neck camper? I am not sure the square footage?** A: For a 40 x 8 roof (320 sq ft) you will require about 1.5 gallons of primer and about 7 gallons of our Liquid Rubber RV Roof Coating. Be sure to measure seams and around vents and skylights and seal those areas with our Liquid Rubber Seam Tape, prior to primer and coating. ## Frequently Bought Together - Liquid Rubber EPDM and TPO Primer – High-Performance Basecoat for RV, Camper and Trailer Roof Protection, 1 Quart - Liquid Rubber RV Roof Coating - Solar Reflective Sealant for Trailer and Camper Leak Repair and Maintenance, Waterproof and Durable.
