Do you find yourself asking: How do I clean and prep my RV roof’s sealants and surface area before resealing with Alpha or Dicor self-leveling sealant? I have answers.
Here is what you need to do.
Steps to prep and clean RV roof sealants and surface
1. Start by sweeping or blowing off anything on the roof surface.
2. Once the surface is clean from debris, you can wipe down the area with Acrysol body de-greaser or mineral spirits to clean the surface. Acrysol will remove any of the old dirt and oils from the roof and sealant surface.
3. When everything is secured properly, then you are ready to begin the resealing process.
You will notice in the picture below that the dirty roof sealants are now back to white again.
Once you have the sealants cleaned to your desired level, you can then start the sealing process. I like to use terry cloth towels or paper towels when cleaning sealant surfaces.

• Tapered Tip Stick and Handle
• Dicor self-leveling lap sealant
Below is a short video clip to see how to apply any roof sealant that comes out of a tube.

mineral spirits will degrade the adhesive holding the membrane to the substrate. CAREFUL
Some will want the old sealant pristine before top coating with new sealant. I have found washing the old sealant with an automotive detergent and a soft-medium bristle scrub brush gets most of the dirt off. Enough so, that top coating with Dicor’s lap sealant has yet to fail. And of course, after top coating, I can’t see those remaining stains on the old sealant.
I wash the entire roof at the same time. then when dry, top coat seals as needed, and finally apply Dicor’s rubber roof UV protectant to pretty much everything. It does cause yellowing of the skylight dome. We don’t care because we applied a ‘stained glass’ window cling to the inside for privacy.
Thank you for the information and links to the different tools you use for the work, Dustin! Have a great day and safe travels!
