Questions about RV Lap Sealant

  • What tools do I need to use with RV Lap Sealant?

    A utility knife to cut the tube and a standard caulking gun is all you need. You will also need to pierce the inner seal of the tube.

  • Can I use RV Lap Sealant to seal side windows?

    No. Because RV Lap Sealant is self-leveling, it will flow into cracks and crevices to provide a superior seal. This is meant for horizontal surfaces only, and will not work well on vertical areas.

  • How long does it take to get my order once I have placed it?

    US - Delivered in 3-5 business days
    CAN - Delivered in 3-7 business days
    UK - Delivered in 2-3 business days

  • Can I coat over RV Lap Sealant?

    Yes. You can coat over RV Lap Sealant after allowing the Lap Sealant to cure for 24 hours.
