- 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.
