Hi there my roof is pretty much black in color now due to the fading of white coating, i am going to try GACO Roof it is a 100% sylicone paint that supposedly is the best stuff on market, does anyone have any experiences with this product?
 
Sorry but can't help you with that one.  I've used the Dicor product and I do know that Henry Solar Flex 287 SF (Home Depot) is used supposedly with good results.  Not much help but what I know at the moment.  ;D
 
Clark...is the product you mentioned used on metal roofs? The RV I just bought was always stored under a roof and the roof is in excellent condition. Sadly, I have to keep mine in the Florida sun uncovered, so I'm looking for a product to minimally re-seal the roof penetrations.
 
Go to your big box store (Home Depot) and get "Henry's Cool Seal" an elastrimeric coating that's easy to apply with a roller, seals, compatible with EPDM rubber roofing and helps cooling.>>>Dan
 
Whatever you choose, make sure it is compatible with EPDM elastomeric roofing. Kool Seal, a widely known and used brand of roof coat, makes a special formula for use on RV rubber roofs. Henry's also has a special formula for EPDM.
 
remember 2 thin coats are better than one thick one, also a two part epoxy primer first makes a huge different, you dont want to be driving down the highway and have chunks of rubber flying off
 
You would not want to use an epoxy coating on any rubber surface, rubber will expand and contract way more than the epoxy and cause problems you don't need.>>>Dan (Thats why an elastic is needed)(Read Gary's post above)

Click to expand...

Totally correct.  On our previous RV which had a rubber roof I only used Dicor's EPDM.
 
Be careful - Dicor also makes a roof coat that is NOT rated for EPDM. Many RV stores carry out and clerks have been known to recommend it for EPDM when it should not be used that way.
 
I have to redo my rubber roof too, is this the right EPDM compatible stuff?

Is this really the best bang for the buck out there?
1 gal covers 50sq feet.

It says it has a 10 year warranty so I guess it will last at least that long with proper care.

It says aged or poor condition roofs may need a primer, what primer do we use?

 
Hmmm, thats really odd.

This is the product I linked but now I cant find it at home depot like I did last night.

I did find the gallon can of the 587, but I still cant find the 5gal bucket on their site.

Ok, I found the 5gal bucket on google but now there is no price now, it looks like I just happened to link it the same night they discontinued it. :D

The price for the 1 gal just took a hike now. :(

I guess they are getting rid of the 587...


Anyways, was that the right stuff?
 
If it doesn't say "ok for EPDM rubber", I wouldn't use it. I checked the tech specs on the Henry's site and it says the 587 product is for previously coated or aluminum roofs, mineral coated roofs, stucco and masonry but nothing about EPDM rubber.
See for yourself:

Suggest you use one of the ones at the PPL parts reference above.
