It provides a low-odor, water-based formula that spreads smoothly and dries to form a strong bond without the flammability or heavy solvent smells of traditional adhesives. The product is not meant for metal, fiberglass, or membrane-to-membrane bonding—use it only where Dicor specifies EPDM or TPO compatibility.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use Dicor 901BA-1 on an RV roof?\u003c\/h3\u003e\n\u003cp\u003ePrepare the substrate by cleaning and allowing it to dry, then apply the adhesive evenly to the roof and the component being bonded. Press the parts together firmly and allow adequate cure time per temperature and humidity conditions. Avoid application when rain or heavy moisture is expected until fully set.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClean surface of dirt, oil, and loose material before application.\u003c\/li\u003e\n  \u003cli\u003eApply with a brush, roller, or serrated spreader for uniform coverage.\u003c\/li\u003e\n  \u003cli\u003eMaintain recommended temperatures and keep surfaces dry during cure.\u003c\/li\u003e\n  \u003cli\u003eNot for metal, fiberglass, or membrane-to-membrane joints—use on EPDM and TPO only.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat surfaces and repairs is this adhesive appropriate for?\u003c\/h3\u003e\n\u003cp\u003eDicor 901BA-1 is intended for moisture-absorbent substrates commonly found on RV roofs, specifically EPDM and TPO materials. It bonds patches, trims, vents, and small accessories to those membranes but should not be used where both mating surfaces are membrane to membrane or on rigid metal or fiberglass panels.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatibility: EPDM and TPO roofing membranes.\u003c\/li\u003e\n  \u003cli\u003eTypical uses: flashing, vent collars, trim, seam repairs where substrate is absorbent.\u003c\/li\u003e\n  \u003cli\u003eNot suitable: metal roof panels, fiberglass skins, or membrane-to-membrane sealing jobs.\u003c\/li\u003e\n  \u003cli\u003eCoverage: approximately 160 sq. ft. per gallon under normal application.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow much will one gallon cover and how should I plan my project?\u003c\/h3\u003e\n\u003cp\u003eExpect about 160 square feet of coverage from one gallon when applied at typical thickness for bonding and sealing. Actual coverage varies with surface texture and porosity, so plan for slightly less on highly absorbent or rough surfaces. For larger projects, order extra to allow for waste, overlaps, and multiple passes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEstimated coverage: ~160 sq. ft. per gallon.\u003c\/li\u003e\n  \u003cli\u003ePorous or textured surfaces use more adhesive; smooth consistent surfaces use less.\u003c\/li\u003e\n  \u003cli\u003eAllow for overlaps, seams, and patching when calculating total need.\u003c\/li\u003e\n  \u003cli\u003eStore partially used containers tightly sealed and use within recommended shelf life.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy choose a water-based adhesive like Dicor 901BA-1?\u003c\/h3\u003e\n\u003cp\u003eWater-based acrylic adhesives reduce solvent odor and flammability compared with solvent-based products, making them easier to work with in confined RV spaces. They still deliver reliable bonding on compatible membranes while being more environmentally considerate. Proper surface preparation and application technique remain important to achieve best results.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLower VOCs and reduced odor versus solvent adhesives.\u003c\/li\u003e\n  \u003cli\u003eNon-flammable formula improves onsite safety during application.\u003c\/li\u003e\n  \u003cli\u003eEasy cleanup with water before cure.\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for EPDM and TPO membrane bonding tasks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Dicor 901BA-1 is a practical choice for RV owners, installers, and repair technicians who need a water-based bonding adhesive for EPDM or TPO roof work. It suits routine maintenance, patching, and attaching roof accessories where a safer, low-odor product is preferred. If you need to bond metal or fiberglass panels or join membrane-to-membrane, choose a product specified for those conditions instead.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use Dicor 901BA-1 on metal or fiberglass?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This adhesive is formulated for EPDM and TPO only and should not be used on metal or fiberglass surfaces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How much area does one gallon cover?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: One gallon covers about 160 square feet under typical application conditions; actual coverage varies with surface porosity.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Dicor","offers":[{"title":"Default Title","offer_id":48082759876766,"sku":"B003VAXDSW","price":121.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/dicor-901ba-1-front-can.jpg?v=1785813410","url":"https:\/\/northtrailauto.ca\/products\/dicor-rv-roof-bonding-adhesive-1-gallon-water-based-acrylic-for-epdm-tpo-low-odor-160-sq-ft-coverage","provider":"North Trail Auto","version":"1.0","type":"link"}
