Seal-Fast® Low-Slope Temporary Roof Sealer is a temporary emergency roof seal product that can immediately seal a roof leak when weather is not permitting for a permanent repair. Seal-Fast comes in a sturdy waterproof container that is easy to transport and easy to use; it keeps all material dry and ready for use. This waterproof container will reduce waste, store easily and eliminate messy cleanup in your vehicle. PERMANENT REPAIRS SHOULD BE MADE AS SOON AS WEATHER PERMITS. Existing Seal-Fast is to be removed from the roof prior to permanent repair work.
