RV sealants protect RV roofs from water damage, leaks, and cracks. They are designed significantly to withstand the harsh outdoor elements and the expansion and contraction of the RV roof. However, sealants can deteriorate, discolor, or lose effectiveness over time. That’s why it’s essential to inspect the RV roof regularly and remove any old or damaged sealant before applying a new layer. RV Sealants Removal can be challenging, but ensuring a proper bond between the new sealant and the roof surface is necessary.
How to Prepare for RV Sealant Removal
Before removing the old sealant from the RV roof, the following tools and materials are necessary:
- Safety goggles, a respirator, or a dust mask.
- Heat gun or hair dryer.
- Putty knife or scraper.
- Stiff brush.
- A vacuum cleaner with a hose attachment.
- Rags and denatured alcohol.
- New RV sealant of choice.
Steps to Remove Old Sealant from RV Roof
- Use the heat gun or hair dryer to soften the old sealant as much as possible. Avoid overheating or damaging the roof surface or the surrounding areas.
