Good Sealant for Sealing our Camper

[BlissRamblyn]

What is a good Sealant to use? After searching the entire lower peninsula of Michigan for a hardside truck camper that was in good shape and fit our budget we found a 1983 Real-lite in great condition. The owners bought it in 1984 and stored it inside the entire time they weren't using it. However it desperately needs sealed and I don't have the luxury of storing it inside. Is there a good Sealant available from home depot, Lowe's, of Napa that would be good to use? I can order ProFlex but it takes a week to get here and it's supposed to rain soon. Should I tarp it and wait for the good stuff or is there something I can buy that will work now. I know to avoid silicone.

While I was looking at Eternabond it mentions rubber roofs a lot. Mine is metal. Should I use Eternabond on a metal roof?

[BlissRamblyn]

Would it be ok to seal the roof seams with Dicor till the Eternabond arrives in the mail. The local RV store had Dicor so that was great.

The 4 inch tape is what I used, and dicor self leveling for the roof.On my roof I did the front nose cap seam and also around each vent with the tape. I think amazon has the best price on a 50 foot roll.

[BlissRamblyn]

Which is better Dicor self levelling or regular? Also which width tape is best for roof seams? 4 or 6 inch. Thanks for all the advice. I want to make it last.

I wonder if the formulation has changed. I had success with this sealant many years ago. Work I did within the past few years failed and I had to strip off the proflex and start over with dicor.

Just found out about Sikaflex-221 which is supposed to be good for any purpose plus withstands the vibration of being on the road.

Cover it until you can seal it properly. I would recommend Dicor. I had issues twice with Proflex. The sealant went on OK but failed to adhere properly. I think the tubes were old and the sealant was not fresh. That happened to me twice with Proflex and I have never had an issue with Dicor.

If you have long roof seams that need to be sealed, I would consider the Eternabond tape. You then use Dicor on the edges of the tape.

If you use the right materials and do a careful job the sealant should work for many years. Be sure the surfaces are as clean as possible. I have even used fine grade sandpaper to prep the surfaces. Then do a final prep with mineral spirits. It can take quite a while to do a good job but it will be worth it to avoid constant fixing and patching or worse areas that still leak.

tarp it until you can get the right stuff. I am not a fan of putting scotch tape on the seams.

Dicor Self Leveling Lap Sealant is an excellent product for caulking horizontal surfaces.
Clean well before applying.

I would tarp the roof until I got the proper materials to seal the roof. But, that's me.

AS much as I like to disagree
I concur with the above
