The Dicor 610SASLT1 Self-Leveling Ultra Sealant is a high-performance polyether lap sealant formulated specifically for RV rooftop applications. Available in tan, this 10.3 oz cartridge delivers a flexible, watertight seal along roof edges, vents, vent pipes, and screw heads — and self-levels for a clean, professional finish without tooling.
Unlike traditional sealants, this formula is solvent-free, isocyanate-free, and HAPS-free, making it safer to apply while still meeting demanding industry performance standards. It is also non-yellowing and UV-stabilized to maintain its appearance and integrity over time.
