Top Tips From This Video

  • Using a Seal-Tite Foamcore Window Kit you’ll have everything you need to do your own window repairs
  • Seal-Tite Foamcore requires no trimming, will not sag or ooze and has excellent temperature resistance in both hot and cold climates
  • The included sealant is easy to apply, yet clears dry to ensure a clean repair
  • To replace and reseal, remove the screws on the interior of the RV window frame and remove the clamp ring before removing the window
    • Use two people, one inside and one outside, to remove the window safely
  • Once the window is removed, remove the old sealant from the window and from the RV itself using the putty knife provided in your kit
  • Clean your window and the RV exterior with a suitable cleaner such as denatured alcohol
  • If your unit has a metal exterior, inspect and replace any old staples
  • Install the new Seal-Tite Foamcore sealant by starting at the bottom where theĀ  components weep holes are located – be sure to leave no gaps
  • Position your roll about 1/8 inch from the window edge and overlap 3/8 of an inch where it meets at the bottom
  • When reinstalling your window, use two people to reinstall the clamp ring and screws
  • Finish the process by applying sealant to the top of the window frame and around the upper window radius
  • Use water and your finger to smooth the seal
