Roof repair and coatings

[GSP7]

Hi. I have a Algo 25ft 5er with the rubber material on the roof.

Ive used Dicor lap selant in the chalk gun form to seal a front corner where I had a small leak do to srinkage and a break in the seal on the front edge.

On these rubber material covered roofs, what is the "good stuff" to use to coat the rubber roof material that is getting sun and weather dryed out.

Ive heard Dicor chalk is good for the edges. whats the best stuff to use to coat the rubber roof? Like something to apply with a paint roller? If thats the best way to apply

I called the RV place and they have some kind of rubber roof coating at $43 a gallon. What about CoolSeal? Cool seal is a latex coating for house roofs or mobil home roofs . Its a white colored material

Welcome to the forum.

Actually Dicor makes some stuff to fix or re-new rubber roofs. I have done this on my old Kountry Star I had and recently on a Thor "Park Avenue".

It is a two part process. (Three step) First you clean the roof very well with something along the lines of Tri-sodium-phosphate. That is to get all the old oxidized rubber roof stuff off. Then you clean it with a mild cleaner to make sure to get all the TSP residual stuff off.

Then after it is completely dry there is a "Primer" coating you use. This actually softens up teh rubber roof chemically so the next step in the process will chemically bond to the old rubber material.

Then the final step is to put several coats of the rubber roof coating material.

It is best if once you get the roof all cleaned to do the final two steps you move the rig into an enclosed area or at leat a covered area. This is to keep trash, bugs and the like from getting into the stuff while it is drying.

I also removed the Air Conditioners and refrigerator vent while doing the ones I did. Then put a new gasket under the A\C when I re-installed it.

It takes a lot of time and elbow greese to do it right. But when done you more or less have a new roof. The materials are not cheap either. I would have to look up the names and prices if you are interested. But on the Park Avenue if I remember right the total cost of materials was something like $150.00 to $200.00...... If you were to pay someone to do this it would be very costly due to the time it takes to do it right.

Hope this helps ya.

Thanks Don, please let me know what product this is. Primer and rubber coating.

Thats about what I expected on cost. I was guessing a 5 gal bucket of the stuff would be about $100-150. How long did it take to dry?

Thanks again, Rick

Actually, if you go to the materials manufacturer's website they recommend only cleaning with a mild soapy water solution. They do not recommend any coating be applied. It has a 10 year guarantee. If you do decide to apply anything, make sure nothing contains any petroleum byproducts, it WILL void the warranty.

Ray,in, Who is the manufacturer?

Rick GSP7 I just recently finished doing my roof and I used a recommended cleaner from Thetford. Now I have a 30 ft 5er an so I had to get Three (3) cans of Primer and Two (2) cans of Seal Coating both were Cool Seal and I used a paint roller it works beautifully and my Roof looks brand new only drawback for me is that it took me 3 weekends to get it done because of high winds in the area blowing dust and dirt so that was a judgement call. If you try it I wish you well and make sure you read and understand all the directions. Bob

I've been lax about replying, sorry. Here is a link to the Dicor website Don is referring to. They have removed the soapNwater cleaning verbiage. Here is another product to seal most anything. To complicate matters further, Protect-All appears to condone the use of petroleum distillates on this roofing material, directly in contradiction with Dicor.
