The Dicor Non-Leveling Ultra Sealant is a high-performance polyether sealant that contains no solvents or isocyanates and is non-yellowing. It’s designed to fill voids and joints and seal around an RV’s roof perimeter and other rooftop accessories where a non-leveling sealant maybe preferred. Ultra Sealant is fast curing, highly weather-resistant, and can be painted with most paints.
NOTE: Polypropylene RV roof accessories and some membranes MUST be primed with Dicor Ultra Sealant Primer prior to resealing.
Before You Order
Check whether the roof accessory is polypropylene or the membrane is one that requires primer; the source specifically calls for Dicor Ultra Sealant Primer in those cases.
