1st time mh owner and I know nothing at this point! 1996 Monaco Signature with fibreglass roof. Want to re-seal everything. It currently has a lot of white sealant that has dried up and looks like it needs replacement. I don't have a local RV dealer, and most people only seem to have seen rubber roofs. I got an RV parts supplier catalog and there seem to be dozens of roof sealer products. What do I want? Can I just use regular GE white silicone or??? Your thoughts are appreciated.

Don't use silicone, it will not seal completely.

Which Dicor product do you refer to? Is it the EPDM Lap Sealant? Isn't EPDM for rubber? Thanks for your help.

X3 dicor
i coated my rv roof this past weekend with dicor, it looks great. i used sponge roller and did twice, unexpectedly i only used half a gallon.

Add: if you see a large gap/crack on your roof, you can use the sealant from dicor as other members have already mentioned, or, if it were me, i would fix it with fiberglass directly - after clean, apply resin to the surface, lay the fiberglass cloth to cover the gap, apply resin again. 2-3 layers will be as strong as a rock.

for small cracks, use resin directly. after done, you can sand and paint.
you may find videos from youtube if you have never done it.

I use Dicor and a seam seal tape that is about 4 inches wide. Also I just clean with soap and water. I have also heard but have not used it. But some people use Mop and Glo to stop the white marks that run off and down the side if RV

I would recommend using the 4" Eternabond tape on all the large openings such as skylights, vents, etc. You don't have to remove the old caulking, just clean it good with Acetone or alcohol, and the Eternabond will seal fine.
You can buy it in a 50' roll which will be less expensive per foot.

I would use the Dicor 502LSW self-leveling sealant on all the small openings such as TV antenna, bath vent pipes, etc. You will probably find both the Dicor 501LSW and the 502LSW. Dicor says the 502LSW is what most professional RV tech use and that it flows better.

Good luck, happy trails, and God bless!

I agree with MS - I resealed my entire roof with 2 rolls of 4" * 50' Eternabond.

Clean the area first with laquer thinner and then lay out the eternabond and starting from one end, pull the clear protective film off and work backwards using a wallpaper edge roller to really press the Eternabond onto the roof. When it is stuck it is stuck PERMANENTLY so go steady and carefully.
It can go over old sealant just fine and that's the end of any leaks for as long as you will own the coach

My advice is get the 4" and don't try and save a few pennies by using 2" - you need that extra overlap just in case there are patches of loose old sealant that you miss.

Ebay had the best prices - I paid $114 for the 2 rolls delivered.

Ok. So it looks like I need to find the 4" tape for any seams, and some Dicor 501 or 502LSW tubes. I think I mostly need tubes for around antennas, screws, vents, etc.. I assume tape is only for straight seams.?

Thanks so much. Really appreciate the help of you experts and your patience with us necomers.

Hello, I have a 85 elandan and also need to do something with the roof. It is in good shape and no leaks but the fiberglass is worn good, story I have not researched decor yet and just wanted to post here to keep this thread in my list for future reference. Is decor flexible for walking on which I would guess, and how much does it cost and coverage rv is 34' thanks.

catonine · 05-24-2013, 06:12 PM

Agree with MSHappycampers. Take your time, do it right and it will last a long time. Eternabond is a great product just be sure to apply as directed and have it where you want it when you put it down. If not, it is a pain to remove. But when done right it will outlast you.

In your situation I would probably go to the hardware store and buy a 5 gallon bucket of Elastomeric. Clean the roof with soap and water and let it dry and then roller the Elastomeric on. As you have no leaks, the elastomeric will create a nice weatherproof barrier - easy to apply, lasts 5-6 years and looks good. 2 coats should do it.

Found the Dicor 501 in my small hometown, and the local Home Hardware (Canada) ordered me a 4" x 50' roll of Eternabond tape for next week. Looks like I'm set for an adventure!

You have received two different kinds of responses.

1. To replace the white stuff that looks old (I would too riding on that roof) use self leveling dicor. I have some 18 year old Dicor that still does it job on my roof attachments.

2. To seal the entire roof surface is another topic and dicor makes a product to spread on the surface. (I think that is not your quest for the moment.)
