Roof Maintenance

Going to do my first recaulking of my 2014 Palomino and want to get it right so where do I use self-leveling and non-leveling lap sealant?

Wipe down the old caulk with mineral spirits, be careful to not get any on the rubber roof. This will clean the old caulk so the new adheres better. Self leveling for flat areas (mostly of what you need) non-self leveling of you need to come down the sides. Don't skimp with the caulk, ugly and overkill is the sign of a well kept roof.

Ruger77.....
Washing the roof (with the correct products) is always a good start and using the correct protection product for the roof will prolong the life of the roof as well.

" lgray " ... is correct about " Don't skimp with the caulk"


- For what it is worth -
However, a very experienced RV teck advised me when it comes to caulking the best prep to clean prior re-caulking would be to use white gas (camping gas).
If used on the roof areas: ONLY ON The Caulking if use on the roof. Do Not Get it on the Rubber Roof .
It evaporates quickly, effectively cleans the back dirt and preps the old caulk for recoating.

>This means any volatile oils or liquids must be used with caution on the rubber roof areas. <

..IMO... Where as 'mineral spirits' is a more oily nature it leave a slight film and may interfere with adhesion.
Again, the same RV Teck advised me against using mineral spirits for prepping caulking on the sides of the RV for that very reason.

Personally I have found that a damped rag with white gas is more controllable to use for prepping or re-caulking than mineral spirits that may spread onto the rubber roof.
[The fear is that any volatile liquids that come into contact with the rubber roof may inter fear with the roof membrane itself or the cement holding it down]

Hope this helps

What you need to do is get rid of the lap sealant, self leveling caulking, acetone, then apply a 4" fiber backed seam tape that accepts a coating, apply 2 coats then never inspect your seams ever again.

The tape is Tape-Kote and the coating is Safe-T-Plex made by Brentwood Polymer Coatings.

Apply 2 coats just over the tape?
