Great Product!
This product was used on an original 2005 Fleetwood Fifth Wheel rubber roof that was in pretty bad shape. Overall, this product worked amazingly! Prep and application are very straight forward, as detailed on the can (also watch YouTube Video-RV Rubber Roof Coating System by Dicor. My only challenge was to get it all done in one day- Applied on a fall day and time to complete was close to ensure enough light remained in the day. Make sure you start as early as possible to ensure you get the 2 coats down. The product applied easier than painting the walls of a room. I did not notice a strong smell and the flow and coverage was really good not sticky- used a roller and paint brush as needed.I ended up purchasing 3 gallons for my 30 ft rig. Two gallons may have sufficed but I ended up applying the 3rd coat the next day-probably overkill, but worth it to me as this roof did not have much left on it and it gave me peace of mind. At the end of the project, I found that the roof looked almost new. I did not notice any cracks or lesions in the roof as the material covered them very well. This product will not solve any issues with roof edges lifting-I used EternaBond Roof Seal Sealant Tape to tackle and concur the edges. This product worked really well, better than I expected and saved me from replacing my roof.

Great roof sealer. Easy to use and apply. A+ 1 gal did my 17′ hybrid.
I had previously ised dicor self level lap sealant to replace my vents and used dicor non sag for trim and seams and to create a condensation/rain run off channel.I skipp3d stage 1. Wasnt a fam of the cost for a quart.I woke up early and scrubbed the roof with a soft car wash brush, Warm water and blue dawn dish soap. I then used a high pressure nozzle on my garden hose and really hosed it all down until the water ran clear, no more grey water or particles visable.I then used a soft bristle broom and swept the water off. And towel dried any spots with a little pooling, I wated until everything was dry, about 40 mintues on a 80 degree day.I then started a thin coat at one corner pouring some out and using a 1/4″ nap roller applied until the roller hissed when rolling and added more paint.While waiting for that to dry enough to walk on. I went around the edged and did the trim with a 2″ brush.Coat 2 I laid on thicker. Then did more trim coat 3 was thick then Inused the bit left over to apply to areas of water pooling and seams.All in all, it was about 5 hours total with some breaks and even a run to my LHS for more paint thinner.This stuff has a odd odor. Like industrial silly putty. Its thick. Like honey or cold maple syrup. Easy to work with. It wont run unless you pour out too much.Keep mixing ans you wont have the gallon skin up on you. If you take a break, cover it with a wet T shirt or rag to stop it from drying uo.If working from the can, get a pour spout snap on lid. It will keep thr can clean when moving around.This stuff cleans up easy with paint thinner and a good microfiber rag.A+ would buy it again!

For Step 1 Cleaner and Step 2 Coating
Used a pump-up deck sprayer to put the cleaner down and rinsed with a pressure washer. Worked great.For step 2, the coating, I used a Grayco airless sprayer. This is the way to go. It was very easy and fast to lay down an even coat.

Good product. My 5th wheel roof was in bad …
Good product. My 5th wheel roof was in bad shape. 12 year old trailer uncovered parked next to house.I worked cleaning roof two hours per day for three days in the early am due to 102+ degree heat. On the 4th day I sprayed the cleaner activator with a new garden sprayer and pressure washed it off after waiting a half hour. There was still a lot of crud on the roof. I ordered more activator and then on my hands and knees I used a small hand held spray bottle. I waited another half hour and pressure washed again. I’m a bit of a perfectionist, and was never happy with how clean the roof looked. After the roof was dry I recoated the roof in three coats of the rubber roof coating. Due to the high heat the coating was trying to dry in the roller pan so there are a few lumps ( not many ) on the roof. Roof is now a bright white and looks like new except where I got some of the coating an the AC lower cover.One thing…..Watch the Dicor Video on the internet, install the plastic sheeting, it protects the trailer sides. The video does not warn you of the mess around the trailer the old coating creates. Took hours to clean that up as well. Be advised, This was a bitch of a job ( I’m 73 } no fun at all, but had to be done. As soon as I’m sure the roof has dried thoroughly I intend to cover it with Dicor protective coating. My wife and I are traveling to the Midwest in September so I’m hoping I did it right and it holds up well.

Great Product-Terrible Delivery-but Amazon made it right!
Product is great- getting it delivered/shipped without being crushed, smashed open, dented with loss of product is another thing!!! Twice I have ordered a gallon of this sealer – the first was sent back by the carrier before I got it due to damage, so I asked for a refund and ordered again- only to receive the second gallon delivery crushed in the box enough to spill INSIDE! There was only a small amount of stuffing paper surrounding the can, so it obviously was not secure in the box!! I originally gave this a 1 overall ….but changed my review- I was lived when I got the second can!Addendum: Contacted Amazon Customer Service and was VERY pleased with the results!! They replaced the can-no charge- and had a new can delivered the next day!!! GREAT SERVICE!!! Now a 5!!

We had this put on our trailer roof when we purchased it. We had a man come today and it is peeling and he had to repair it. I would not recommend anyone purchasing this product.

Arrived quickly after ordered. Good instructions. Easy to apply and wash off with pressure washer. Pleased with the amount and ease of dirt that it did lift and remove.
