RV Sealant Removal

RV Sealant Removal
RVs are more like houses than cars in the respect that they have seams. Those seams are typically sealed either with caulking or with a tape-style sealant. Such RV sealants wear out, and when they do it is often necessary to remove the old sealant before applying a new layer. While the procedures for removing RV sealants are simple, they involve a considerable amount of tedious scraping.


Difficulty: Easy

Things You’ll Need:
  • Razor blade
  • Flat-headed screwdriver
  • Putty knife
  • Scrub brush
  • Car wash detergent
  • Hair dryer
  • Acetone-based solvent

RV Caulk

Step 1
Inspect the old sealant and decide how much you wish to remove. If you are not removing the entire bead of old caulking, cut into the bead roughly 2 inches down from both ends of the worn-out caulking. Pry up the ends of the old bead of caulk with a flat-headed screwdriver.
Step 2
Pull out by hand as much of the old caulking as you can.
Step 3
Scrape off any remaining bits of caulk. For RVs with fiberglass shells, a disposable razor blade is required. For all other surfaces, a putty knife will do.
Step 4
Wash the caulk with car wash detergent and a scrub brush and clean out any grime in the seam.

Tape-Style Sealants

Step 1
Heat the end of the tape with a hair dryer set on maximum for two or three minutes.
Step 2
Pry up the end of the tape with your fingers and gently pull the tape off. Cut the gooey adhesive/sealant underneath as you go with a razor blade. If you reach a stubborn section that refuses to come up, stop and heat it with the hair dryer. Do not continue pulling and risk tearing the tape.
Step 3
Remove the residual bits of adhesive/sealant on the RV by either scraping it off with a razor blade or applying an acetone-based solvent and wiping it away.
