Dicor RP-IRC-1 CoolCoat Roof Coating - 1 Gallon, White, 128 Fl Oz (Pack of 1)

Just did my roof. I have a 36' motorhome but only 30' is EDPM. So base on what Dicor say I needed 4 gallons. We used 2.5 gallons on three layers. Dicor say to put a minimum of 2 layers so it means 2 is a minimum. The roof is now white but we can still see where it was black before. So I could put 2 more layers or 3 and then spend 4 gallons. So 4 gallons is possible but people quit after 2 or 3 layers.The result is very good. We were able to do it in a single day. We put plastic paper all around the motorhome just in case, it was 2 hours job to put this on and was not very necessary in my opinion.J'aif fait mon motorisé de 36' mais j'avais seulement 30 pieds de toit à faire. Par conséquent selon ce qui est écrit sur le pot je devais mettre 4 gallons sur mon toit. Nous avons mis 2.5 gallons en 3 couches en une seule journée. Mettre 4 gallons est possible si on met 2 ou 3 autres couches. Et on pourrait les mettre car on voit que les anciennes sections noires sont encore grisées. Mais je crois que les gens abandonnent après 2 ou 3 couches. Dicor dit de mettre un MINIMUM de 2 couches mais deux couches sur mon toit = moins de 2 gallons. J'ai mis une toile tout le tour du motorisé comme Dicor dit de le faire mais dans notre cas cela n'aurait pas été nécessaire à mon avis.I have a Fleetwood Pace Arrow Vision 1999. Fleetwood have EDPM Alpha type roof so it is very important to put the primer first.J'ai un motorisé Fleetwood Pace Arrow Vision 1999 qui a donc un toit EDPM de type Alpha et c'était donc primordial de mettre la couche de préparation-nettoyage comme première étape.

I finished this job yesterday. My RV roof is approximately 10 feet by 18 feet (180 square feet), minus area taken up by the AC and the bathroom vent fan and the vent over the fridge and other miscellaneous vent pipes. One gallon of this says it will do two coats of approximately 120 square feet so I bought two gallons thinking I might end up with perhaps enough for a third coat. (I also bought two bottles of the mandatory soapy activator prep liquid). We started our job at about 9:30AM taping up the plastic sheeting around the entire circumference of the RV, and I think I was spraying on the soapy activater prep liquid about an hour later. I should probably tell you at this point about the condition of our roof. This roof is 15 years old and has never had any maintenance that I know of. Although there were no tears or damage, the roof was so neglected that the previous light-colored rubberized coating was almost completely gone, and the roof was much more black (the rubber?) than white! In fact, as I crawled onto the roof, the black roofing material was so deteriorated that the topmost layer was basically black powder which instantly adhered to my sweaty hands and quickly got on my shoes and clothes. (I should have put my gloves on before climbing the ladder!) I sprayed on the activator and let it set for about twenty-five minutes before using the pressure washer. The activator combined with the pressure washer resulted in pretty much all that was left of the old roof coating to wash away, along with lots of black powder. I let the roof dry for about an hour before beginning with the coolcoat. I used a fresh roller for each coat of this product, with about an hour to dry between coats. My temperature was about 78 degrees and humidity was about 45% which seemed to do well in making the coolcoat dry to the touch in an hour. The first coat used about 3/4 gallon. The second used about 1/2 gallon. The third coat used about 1/3. I had enough to do four good coats and I finished about an hour before sundown in the middle of July. Today I walked on the roof and felt no areas of concern regarding drying. A few tips: don’t bother using a paint tray. Just pour straight from the can onto the roof. The tray is just one more thing to get in the way, fall off the roof, or create problems in other ways. That being said, my next tip is don’t pour out too much at a time. Working on a black roof in direct sunlight made that stuff dry almost immediately! In some cases, it was too dry to spread within mere minutes of being poured onto the roof! Another tip: although this product is water based and you could clean out the same roller after each coat, I chose instead to just buy extra rollers ahead of time and I used a fresh one each time. It takes a lot of water to thoroughly clean a roller and we’re suffering a water shortage where I live so there’s the reason for my choice. I did try to wrap up a used roller in plastic to preserve it for the next coat, but it didn’t turn out well. I also recommend wearing rubber gloves, but I don’t know that I’d call that step necessary, except maybe for the activator which is not water based. Another tip: while on the roof, I found several gaps in the old putty that was originally used along seams and to waterproof screw holes and such. I wish I had gone up there maybe two weeks earlier. That would have allowed me time to order several tubes of the dicor self-leveling caulk and maybe done that as a separate job a week earlier. As it is, I’ll do it now as a separate job later. As for the effectiveness of the coolcoat, I can tell without a doubt that the inside of my RV is definitely cooler than it would be on a day like today! However, I’m comparing the coolcoat roof to the previous black roof. I don’t know how much difference there might be between the coolcoat roof and the regular dicor roof coating, or between the coolcoat roof and an RV roof that still has most of its old coating intact. One final tip: either do a better job putting up the plastic sheeting than we did, or skip that step altogether. We spent an hour putting it up with frog tape, but it was no match for the pressure washer! We ended up doing an emergency RV wash after rinsing off the activator because that black liquid mess ran down the sides of the RV as if the plastic wasn’t even there. And I shudder to imagine how much more difficult that job would have been if we didn’t address it immediately. That black liquid mess was hard enough to clean off while still wet! All in all, I’m happy about how it turned out. I can already feel the temperature difference and I know that roof needed the renewal that this coating provided.UPDATE: It’s been a month and I’m getting the trailer ready for a trip. I climbed a ladder to make sure the small gutters were clear of debris and that obviously put me where I was able to see the roof. Instead of the pristine and flawless new roof that I expected to see, I was horrified to see that my new roof has blisters all over it! Most are the size of a dime, but some are as large as a teacup saucer! Pushing down gently, it’s clear they’re air pocket bubbles. I found one under a vent cover that I experimented with and it easily tore open completely, exposing the original roof below the multiple coats of this product that I had applied. I don’t know how this happened. I used the obligatory spray-on primer, and I thought I followed the directions for this product as specified. And it looked good when I finished the job. But now it looks terrible, and is clearly not going to last. If I back into a camping spot under a low-hanging tree branch, that will surely rip through these fragile bubbles! I’m thinking that means I will have to remove all of this expensive coating and completely re-do this job with some other product. Sadly, it looks like this job ultimately ended up being a complete waste of my time and money and I’ve had to downgrade my review.

I recruited my son for this job. I wanted to coat the roof to extend it's life and stop the chalking streaks down my 5th wheel. Spent 3 hours wrapping it with plastic per advice from manufacturer. Then did step 1 with care, not to overspray, then scrubbed and rinsed for about a 1/2 hour. Waited for dry time, didn't take long in 74° and sunshine. Then did 2 thin coats with step 2, with ample dry time in between. Looked really good and felt good that time to make sure it was done correctly. 2 weeks later I check on the roof, 90% looks great. The 10% that didn't looked as if we trapped air under the coating?? I could push small areas down, so it wasn't bonded?? then had three areas that my shoe broke open the air pocket to expose original roof. I was surprised how easy it was to tear. Happy about most of the roof, just disappointed that I had to emergency RV tape repair opened areas.Update. Sooooo over a month later I go up on my rv roof to add vent covers, I was so disappointed to see this coating cracking apart in multiple spots! What the heck! I now am really questioning the product. Most is still in good shape, but now I have to buy another gallon to fix all the spots that have cracked. With all the time and cost, I wish I had not coated my roof! No way to get a refund either....Update#2- I contacted Dicor customer service and explained my issue with the Cool Coat cracking. They quickly responded and let me know that I made the layers to thin. I was really shocked and pleased that they are re-supplying me with the correct amount of gallons and they are sending the activator (part 1) also, for no charge. Thank you Dicor customer service for making my situation correct, even when I mistakingly made it to thin.

I've used this product before and happy with the results. Repeat customer. Only problem I experienced was not with the product but rather shipping. It was packaged perfectly, but was laid sideways in the box, which is no big deal except the address label was also put on the side so product was shipped laying on its side. It leaked.

I'm very happy with the results and definitely feel cooler inside the camper, even in Florida heat. Noticeable decrease for inside temperature and the AC runs less frequently compared to last year without the roof coating.First gallon I applied was expired, the product was watery with chucks, and applied like a primer. Second gallon was thick and creamy like meringue, applied thick.Easy and fast replacement, no fuss, and then reapplied the replacement gallon.Used the activator/clearer first, then washed with a rental pressure washer.Two quarts of the #1 Activator and two gallon of the #2 coating were enough to do a 28ft roof with one large slide-out RV.
