Our camper is 2 years old. I check the roof on average 3 or 4 times per year and wash it twice. Each time I touch up questionable spots all over the roof. Today I added quite a bit along the front seal where the roof meets the front cap. My question is, when (if ever) do you, or have you decided you have put on enough, it's time to pull it all off and start fresh? I feel like continuing to add cant be a great idea long term. Our previous camper which we had for nearly 15 years we had Eterna bond, but I am not interested in using that at this point on this trailer. Anyway, do you all just keep adding or do you eventually somehow remove the old and reseal the entire roof or sections?Thanks

If its comming off and dry remove it and start over if not clean it with mimiral spirets and re apply.

My camper was a couple of years old when I bought it. There were only a couple of problem areas and I replaced the sealant in those areas. Over the past 10 years I have mostly just added extra sealant in high risk areas. I would think a thorough inspection would give you an idea of what is needed. I have repeatedly checked every square inch of my camper. I have added additional sealant almost everywhere. Under ideal circumstances, dicor should last for decades. The bigger issue is usually poor design or poor construction. Joints can flex and open up on a poorly made RV.

I have cut back and or removed and resealed when the time came. It all depends on the area you are doing.

If your camper is only two years old, I am surprised it already needs dicor. When you wash it, I hope you put the preservative on afterwardsGuy

Have you considered using Eternabond where possible?

Now this just my opinion not tossing tomatoes at anyone here, but I would rather see what I got for a problem not have tape covering it. not being able to see where a problem is, is important. If Dicor has a problem you can see it by close inspection usually.

I suspect Eternabond tape would perform a lot better if the membrane tape portion was the EPDM rubber roof slitted into strips or tapelike form. Not a plastic or vinyl membrane tape.

I've witnessed it lifting. Yep actually curling up on the edges and then highway speeds make the curl catch wind and gradually pull loose enough exposing the damaged area underneath. It leaked. The plastic tape shrinks and curls then wind and suns heat does the rest.It turns to something I won't use.

Were seeing more and more issues around the net with the tape as more folks are using it on their rvs.... even if it was applied properly. Properly or improperly installed Its still a good idea to seal the edges with Dicor or any good sealant made for rv roof application.

I didn't apply the curled Eternabond it was an RV that came in that way for a new roof. When we applied the new roof we went with two coats of the roll on adhesive and worked well for bonding to the roof. Plastic shrinks in UV light and thus the curling. If you guys are having good results though, I think you should use it. I like the smoothing out working into the surface back and forth with the Dicor and straight line masking.

Well then your post is even more misleading since you have no idea how the Eternabond was applied originally. Also, your "ASSUMPTION" IMO a somewhat poor one at that is simply incorrect as it applies to the covering on Eternabond. I have more Eternabond on my roof than I would guess 99% of the posters here and after 12 years of it sitting uncovered outside not a single piece has curled/shrunk or come loose except for that very front edge on my front cap roof seam. All of it looks as good as the day back in the Spring of 2008 that I originally applied it.

Regarding eternabond it's easy to get mixed reviews. Lots of online reviews of people having water work it's way under and it turns into a mess.

IMO that statement about "LOTS OF ONLINE REVIEWS and WATER", is simply NOT TRUE. Unless it's improperly applied or the product is defective (Eternabond does have a shelf life of around 5 yrs), water simply will not work it's way under the tape.

I've seen that too. On my own RV. It only happened once. I believe it was that evil bad run of product they had at one time. I've used probably 150' of the stuff over the years. I've also used the Dicor product. Eternabond is a much more permanent, and reliable solution.

Your issue was improper application. Eternabond clearly states that when a leading edged is exposed perpendicular to the seam at uninterupted highway speeds that leading edge can come loose and they recommend applying a thin layer of sealant/caulk to that leading edge to prevent that issue. I had to do that on the very front strip on my front cap Eternabond strip to prevent it from coming loose.

Also the poster complaining about the covering shrinking is again actually improperly applying the product since you absolutely cannot pull or "stretch" Eternabond over anything since the microsealant is elastic and will pull loose over time if under tension.

i think the OP needs to find another hobby and give the roof a rest/break. My 10 year old roof has never been washed.

Lap sealant comes in self-leveling and regular. The self-leveling should run down into crevaces and such with no need to brush on. The tape is a good idea.

St clair is made up, but a location was required when registering, even for those who prefer more private internet security...

Yes it does, However working it into the surface both directions has an added benefit on the micro level. Kind of like the difference between brushing paint to work it into the surface for greater adhesive quality. Then the masking makes for a professional straight line job while working it back and forth into the repair.
