Henry Tropi-Cool roof coating

[lonfu]

99 pace arrow 35u ft with black EPDM rubber roof. need to use some roof coating. Looking at the henry brand of Tropi-Cool 4.75 Gal. 887 White 100% Silicone Roof Coating. Says it goes on without any primer but was wondering if anyone has any experience with this specific product for RV EPDM roofs. Life time warranty...... AND NO it is not a pebble finish alpha finish. I've used hennery products for a lot of other roofing projects with great success. Metal and roll roofing. Looks like $200 for a 5'er at home cheapo. guessing at least to use 3.5 gallons for 2 coats perhaps more. Any suggestions or recommendations????????????

Check the label. If it doesn't explicitly state compatibility with EPDM rubber, do not use it without a primer. Henry's has some EPDM compatible products, but I don't know if that is one of them or not. If it is all silicone, I would guess NOT.

Or contact Henry's Tech Support and ask about use on EPDM rubber roofs

Oddly enough it says it says it is compatible with epdm. That is why I wondering if any one has any practical experience with it.

I have never used Henry's coating so can't say how good it will hold up. I used EPDM Liquid Roof on my 5er 6 years ago and it sat outside in the weather 35 Miles from Williams AZ. for 5 years. It still looks as good today as when I did 6 years ago.

Thanks for the advice. I looked at this stuff and it looks to be about the same stuff with a different solvent. the henry stuff seems to be one part and they claim as good for a lifetime warranty. I"ve used Koolcoat on my 26 class a for 25 years with great success. usually lasts about 10 years or so before needing recoating. works on metal or fiberglass.

Problem is that with the shipping it is at least 2 times more expensive as the henry's that is available at my local Home Cheapo....

Ok, new EPDM rubber roof runs about $9 per foot, or about $450 incl tax. plus caulking or tape. I would have to pull all the fixtures on the roof and side rails. Then I would coat it with Henery's to insure no leaks. Same stuff that is currently on the roof. Installed price is going for about $85 per foot or about $3000.00. Henery's Tropi-Cool was $200 for a 5 gallon pail, $10 for 1 tube of caulking and 2 rolls of Useal roof tape @$17 per roll.

I've used4 1/2 gallons for 2 coats. this stuff is amazing, it looks like and feels like rubber. Dries to a semi hard film. Some very sticky stuff. Comes in ones and fiver's. You will need to do a minimum of 2 coats. Trick is the prep, clean and no oil. Yes, I spent about 5 hours just cleaning the roof and pulling the ac covers with the wife washing the side of the coach to prevent the black from sticking. I used Dawn dish soap in a spray bottle. It was the brushing that did most of the cleaning. I spent another 3 hours taping the different vent bases. Took about 4 hours for the first coat, and a day later, today 3 hours for the 2nd coat. But.... it looks great and seals all the rock and pin holes.

I really noticed that on one side the rubber roof had shrunk and pulled away from the rivets. The tropi-cool roofing coating has filled in those holes left in the rubber roof and other places. I coated the vent roof jacks to protect them from the AZ sun. Also, I coated the wires to the TV antenna too! This stuff is self-leveling really hides any booboo's in the roof. Amazing liquid rubber like coating. I found it difficult to work with because it is so thick and has to be cleaned up with mineral spirits. I ruined my cloths and shoes..... BUT....the upside to the mineral spirit clean up is that it is not water permeable, so if you get a little puddle by your front/rear cap, upside of your vents, no problem, it won't turn to mush like some of the water soluble roof coatings.

After cleaning with dish soap and water.

I used some white Henry on an older trailer.

Pro:
Went on easy
Kept the unit noticeably cooler
Never leaked
Relatively inexpensive

Con:
It never quite dried. It always stayed slightly tacky meaning anything that touched it stuck. I had fir and pine needles semi-permenatly stuck to the roof. Collected dirt like crazy.

It was nice on the cheap trailer I had at the time, but I would not use it on anything I wanted to keep really nice.

Hmmmm, I wonder if you mixed it well enough first? I've use Kool Seal on 2 of my moho's with out that problem, but it was latex based. Then I use the henery enviro white on my other house patio rool roofing with great success. And now the tropic-cool on "Brenda". I've never had that problems with any of these products. BUT..... I found that in every case I had to use a mechanical stir of some sort to mix the material. Just shaking the can doesn't work like paint. Laying down the tropi-cool is like putting on a new rubber roof. I'd guess almost as thick as the dicor material. I was thinking that I could probably put this stuff right over wood and create a roof. Yes, it is that good.

Cheap? Not at $50 per gallon for my pocket book. It was $200 for a 5'er. Ouch!!!!

That said, as we all know, it is the test of time, ultra violet rays, rain and vibration that tells the true tale! Saw a mouse climbing up the rear "sweep" yesterday. The string kind of thing that prevents rocks from hitting the toad. Never gave any thought on how they were getting to the top of the gas tank. think I will pull it off.

Ok, got the 2nd coat on. this stuff is like silicon rubber. I didn't have any lifts and only one touch up where I missed a spot. It does stay kind of well "rubbery" it is not tacky, but has a silicon feeling to it. Stuck to everything. Tape on eve trim came up without lifting the coating. I"m a little concerned about the silicon "feel" to the stuff. The inside temp has dropped 15 degrees, but still questioning the Lifetime Warranty of this stuff? Guess only time will tell about that. AZ sun here is brutal, so I'm sure it won't take long. I wonder if this stuff would keep the birds off my porch ceiling fan? kind of a sticky feeling to it?

OK, fella I FB with just did a roof job, charged $4300 for a 29 foot class A..... Ouch!!!!! I only paid $6 for the entire coach.

I'm having problems getting the masking tape to release from the front fiberglass cap. For some reason it just won't come off without me scraping it off. Came off everywhere else with no problem. I've tried soaking it in paint thinner but that doesn't help, but does take the glue residue right off.

Any suggestions?

I used Lanco Ultra-Siliconizer to re-coat my roof.

I changed from the crank up satellite and antenna to 2 Tailgators and the king HD antenna. I found that I needed to do something to totally seal the roof holes the changes made. My original plan was to eliminate the refrigerator vent as I installed a residential refrigerator and no longer needed it. Also I had a roof leak above the bathroom that caused damage in the wall.

I bought the polyester fabric to put around vents and on the cable wires. I ended up leaving the vent installed and just coated and sealed the whole vent. I sealed around all the vents, A/C, Satellite mounts, ladder, edge on both sides, skylight, end cap, and front cap. I applied 2 coats on all of these.

I replaced the sewer vent with that siphon 360 and found my water leak. The sewer vent was not properly installed so there was water running down the pipe. into the bathroom wall. I fixed the wall and roof and sealed and coated it then installed the new vent and sealed around the new vent cap.

After completing the prep work I applied my first coat on the whole roof. There was un-forcasted rain that night so it washed part of it off. I applied another coat in that area where it was washed off which was only about a 5 foot section in the back of the coach. After completing the first coat I had to take a few day break before applying the last coat.

I let a coat dry on a piece of plastic and so I could see the thickness. The product has a nice thickness and seems to be very durable. The roof project cost me a little less than $200.

The pros:
Very easy to apply
Cheep and easy to get

Easy Cleanup

Cons
Not self leveling so finish is not as polished as the more expensive products

Ill see if I can post some pictures tomorrow.

Got the tape off. tried carb cleaner and lacquer thinner. the lacquer thinner worked the best for the glue. I finally had to get out my heat gun and heat it up until the paper came unstuck from the glue. This was 3m standard masking tape. I remember using this same tape and it tore the paint, primer and texture off my ceiling in my project house. At least $1000 damage. I figured at the time that I must have screwed up the texture. I Won't use it again for painting. Not sure why this happened but this is not a good tape for painting. I' ve been using standard masking tape for years for all kinds of painting, house and automotive but this is first time I've had this happen on a automotive surface as well as house paint. Would be good for packing a package!
