It is aimed at RV owners, roof repair DIYers, and technicians who need a primer that promotes reliable adhesion of Dicor's ultra sealant to plastic appliances and roofing materials. The single biggest reason to buy is its role as Part 1 of the ultra sealant system: using this primer is what enables the sealant to bond and remain effective on horizontal and even some vertical surfaces.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart of a two-step system:\u003c\/strong\u003e Designed as Part 1 to prepare TPO and EPDM so the ultra sealant will adhere properly for a long-lasting seal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface preparation:\u003c\/strong\u003e Must be used on plastic appliances and roofing membranes to remove barriers to bonding and improve sealant performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-grade materials:\u003c\/strong\u003e Manufactured with premium materials to provide consistent priming and reduce the chance of adhesion failure when followed by the sealant.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear formula:\u003c\/strong\u003e The clear 16 oz formulation allows precise application without altering the appearance of the roofing or appliances.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEveryday usability:\u003c\/strong\u003e Straightforward to apply for routine maintenance or seasonal roof checks, making it practical for RV and rooftop maintenance tasks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe primer is best for RV owners, roof maintenance professionals, and DIYers working with TPO and EPDM membranes who plan to use Dicor ultra sealant.
