  • Our take on the Dicor Ultra Sealant

    Dicor Ultra Sealant is a self-leveling polyether sealant in a 10.3 oz caulk-gun tube, made for sealing around rooftop accessories and filling voids and joints on RV roofs, including TPO membrane. It is solvent- and isocyanate-free, UV stabilized and non-yellowing, and it cures fast. Compared with Dicor's older self-leveling lap sealant, the polyether base is aimed at better adhesion and cleaner handling on TPO, while staying paintable with most paints. It suits RV owners doing their own roof maintenance who want a pourable bead that flows into seams and around vents, skylights and antennas.

    Pros
    • Self-leveling formula flows into seams and around fittings without tooling
    • Polyether base free of solvents and isocyanates
    • UV stabilized and non-yellowing for long sun exposure
    • Adheres to TPO membrane and most common roof substrates
    • Paintable with most paints
    • Fast cure shortens roof downtime
    Cons
    • Self-leveling means it runs on sloped or vertical surfaces

    • Needs a standard caulk gun and clean, dry surface for good bonding
    • Not a substitute for a roof patch over large tears

    What reviewers say

    Owners of TPO and EPDM roofs report the sealant flows out smoothly, skins over quickly and holds around vents and skylights through weather. Complaints center on runniness on sloped areas and the small tube size for larger jobs.

    What people mention
    • Self-leveling flowPraisedOwners say it spreads and levels on its own, filling seams and voids around rooftop fittings.
    • AdhesionPraisedUsers report it bonds well to TPO membrane and holds through weather when the surface is prepped.
    • Slope behaviorCriticisedReviewers note it runs and drips on sloped or vertical areas, so it is best kept to flat sections.
    • Tube sizeMixedSome owners find the 10.3 oz tube enough for small reseals, while others say larger jobs need several tubes.
    • Cure timePraisedUsers say it skins over quickly, letting them finish roof work sooner.
    • YellowingPraisedOwners report the white bead stays bright rather than yellowing in the sun.

    Questions and answers

    Is Dicor Ultra Sealant self-leveling or non-sag?
    It is self-leveling. It flows out to fill voids and joints on flat roof areas, so it is not the choice for vertical or sloped seams.
    Can it be used on TPO roofing?
    Yes. It is formulated for RV rooftops and lists TPO as a substrate, along with sealing around rooftop accessories.
    How is it different from standard Dicor lap sealant?
    Ultra uses a polyether base without solvents or isocyanates, is UV stabilized and non-yellowing, and is aimed at strong adhesion on TPO. Standard lap sealant is the older, widely used self-leveling formula.
    Can it be painted?
    Yes, with most paints once it has cured. Check the paint maker's guidance for flexible sealants first.
    How much does one tube cover?
    Coverage depends on bead width and joint depth. A 10.3 oz tube handles small reseals around a few fittings; plan on multiple tubes for a full roof.
    Does it need a caulk gun?
    Yes. It comes in a 10.3 oz tube and is applied with a standard caulk gun.
    Where is the Dicor Ultra Sealant cheapest?
    At Amazon, for $10.50, 38% under what the other stores charge, as of our latest check.
    Where can I buy the Dicor Ultra Sealant?
    14 stores we checked sell it, including Shell Lumber and Hardware, Boats.net, Tweetys RV and Truck Accessories, etrailer.com, RV & Auto Parts.
