Cleaning the roof before using this product was the hardest part applying the liquid butyl rubber was simple as pouring out and spreading it around. i was worried about bubbling of this product but after five days the roof is flat and smooth and looks very good and looks to seal around vents and pipes very well i used five gallons for my 30 foot camper and would use this product again.
I have a 1996 25 foot camp trailer that has a rubber roof that needed coating. I did a lot of research before deciding on Liquid RV Roof. I already know that EPDM roofs are great and I was very happy when I found this product. The trailer roof had just a few very small holes and one small tear at the edge about 1-inch long. I washed the roof with a high pressure hot water washer and a great degreaser. Almost all of the old coating came off. I chose not to patch or reinforce any of the small holes. I opened and mixed the Liquid RV Roof product as per the instructions. With a friend to help me, we began to apply the thick mixture. It was a breeze to apply. Having a squeegee and roller is key. We applied on a nice cool day at about 70 degrees. We chose to do it in a location free from trees and debris. We applied about three gallons to the roof. (I bought 5 gallons...oops should have measured...not guessed) It only took about 1.5 hours to complete the application including doing the edges with a brush by hand. It took about 72 hours for the wrinkles to flatten. The small tear and pin holes were coated perfectly and sealed great.
I finished the painting of my roof yesterday with Liquid Butyl Rubber, an EDPM rubber in liquid form. The results turned out great. Here is the product I used and the process I went through http://www.epdmcoatings.com First, I scrubbed the roof with a bit of Awesome Cleaner from the local Dollar Tree store. I mixed in an ounce or two of auto liquid cleaner also and added a few gallons of water in the bucket. This did a good job of cleaning the roof.
I let it dry overnight and then taped the edges all around the whole trailer with blue painter tape. This job took me a few hours and I was bushed from going up and down the ladder so quit for the day.
That night we had a heavy rain and here is what the roof looked like the next morning. I let it dry out well and about noon I was ready to begin the paint job. As you can see from the above pictures, my roof, which is about 8 years old was losing it's coating and had many spots which were caused by both bird droppings and "berries" from the local palm trees. I try to clean my roof at least twice per year but it was time to do something about its condition.
I started out by mixing the product with the product. It is advisable to rent a mixer that has the power to do the job. The Liquid Butyl Rubber is very heavy and will burn out a normal 3/8 or 1/2 drill motor quickly. You need to mix it thoroughly which takes some time. I rented a mixer from Home Depot for $12 for a whole day. Well worth it! Here is the mixer I used. It is advisable to have a helper available to hold the can and pour the product into the product. It will take both of your hand and feet to control the mixer as the product is very heavy and thick and causes a lot of drag and twisting force on the mixer. After mixing in the product, you have about 4 or 5 hours of working time with the product. I purchased the product in one 1 gallon can and one 4 gallon can. I mixed up the 1 gallon first and used that to do around all my "stuff" up on the roof and around the entire perimeter of the trailer. I removed my vent covers for the cutting in and then replaced them before doing the rest of the roof. This used up about 3/4 of the gallon. The rest I used on the top of the roof. The product is supposed to cover about 40 sq feet per gallon if applied as a 20mil thick coating. That turned out to be a very accurate figure as I had only a small amount left when I finished.
Here are a couple of pictures of me doing the trim around the edges. That "supervisor" is my good buddy Jim, a retired Navy Master Chief who also helped me with the mixing of the product. After doing the edges and cutting in the opening on the top, I got busy doing the rest of the roof.
I made a mistake thinking I would just pour the stuff on the roof and spread it with the roller. It is too thick to just use a roller and a squeege is needed. You pour a line on an area, spread it out with the squeege and then smooth it with the roller. The stuff is self leveling so you don't have to worry about ridges or getting it perfectly smooth. The idea is to try to get a nice even coat.
I don't have any pictures of this process as nobody else would climb up on my roof and my hands were too sticky to operate a camera. This product is very sticky and you must wear old shoes and old clothes as you will get some on you and the equipment. It cleans up with paint thinner or mineral spirits but I just threw out the squeegee and paint brushes and rollers.
Here are a couple of pictures of the finished product. It dries to a kind of semi gloss finish which looks great. It is not quite a shiny now as it looks in the pictures. Another thing is that there are a few spots where the rubber roof seemed to develop bubbles - mostly near the edges on the flat part of the roof as you can see in the 2nd picture below. This is normal according to the manufacturer and should go back down. We'll see if that happens. Notice that it is applied right over the Eternabond tape that I put on about 5 years ago. That tape still looked like new
Some Tips others haven't mentioned.
This a great product, EPDM Rubber for roofs. It is easy to mix and easy to apply. I had a roof job where a company applied a "torch down" rubber system on my flat roof. They made several critical errors in the application of the torch down. Two added roof repairs and four internal ceiling repairs later and the roof seemed tight. Once you are burned by incompetent roofers you become a cynic quickly. Because of arbitration I got some of my money back. I certainly did not want those bozos back on my roof.
Water stands on my flat roof in various places. I decided to apply a coating of EPDM Rubber over the roof for added measure. So I bought a gallon and applied it in a critical area. It stayed tight and looks great. I waited for several months during the rainy season and had very positive results. I then bought a five gallon pail and applied it to a larger surface. Looks great and adhesion is fabulous. It bonds great with no distortions of bubbles.
I think the easiest thing was that I had a fairly solid surface with which to work. So, cleaning and surface prep seems to be critical. If you prepare the surface well your application and results will be outstanding.
I just ordered two added five gallon buckets and plan to coat the remainder of my roof. I use a short nap roller and it goes on with ease.
I fully recommend this product for roof repairs. Just follow the directions and anyone can do this with completely positive results.
I would like to thank you guys. I have tried just about everything out there and nothing worked. The hardest part of the job was mixing the hardener. What was really amazing is how the roller marks just disappeared in a couple minutes as the material leveled itself. Really quite a good product.

My 1998 Overland Lorado motor home has an EPDM roof that is showing its age.
Chalking and small cracks are evident and the roof has had numerous repairs by the previous three owners. I researched roof coatings on the internet and concluded that Liquid Butyl Rubber was the best product for restoring the roof.
I live in Boston and have trees overhanging my driveway so I decided to apply the Liquid Butyl Rubber while in Tucson Arizona while staying in a RV resort.
I ordered 8 gallons on Monday and it arrived on Friday, much faster than I expected. I bought the tools at local stores (paint brushes, roller, squeegee, wire brush and cleaning supplies). I found the Instructions and You Tube videos helpful in planning the project. Preparing the roof took about 10 hours (cleaning, brushing, patching with butyl tape and taping edges). Applying Liquid Butyl Rubber took about 6 hours and most of the time in the mixing and painting the edges using a brush. I found a hand held 12 squeegee worked well in the tights areas of a motor home roof. This was a one man job and can be done by someone with moderate home handyman skills. The roof looks great and I expecting many years of added life with no leaks.
Thanks for your help.
I am sending this email to sing the praises of Liquid Rubber. My husband died in 2009 of brain cancer just before his retirement leaving me with all of the home maintenance projects he had planned on completing in his retirement. Re-coating our mobile home roof was one such major project. I tackled the project in the same manner I had watched my do it yourself husband complete tasks all his life. I started out at Home Depot and Lowes examining what was available and asking a lot of questions. Our small motor homes roof needed to be re-coated also, and I thought I would start with that to gain confidence and to make sure I was indeed capable of completing the task of the larger project of the mobile home roof. At the home improvement stores I was met with skepticism, encouragement, and amazement. Next, I went online to check out some blogs on people re-coating mobile home and motor home roofs (that strategy I learned from my son) and discovered most were saying the same thing: Liquid Butyl Rubber is the best. Finding it was not sold in stores, I ordered gallons from you to re-coat the motor home and plunged in. My brother helped me by removing all caulking, patching a ripped portion of the roof, and holding the drill to mix the chemical in the Liquid Rubber, with my father in his 80s pouring in the chemical as I held the gallon can during the mixing. As you can see by the pictures, the motor home roof looks fantastic, the liquid butyl rubber was amazing to work with, my confidence soared and I began work on the mobile home roof with the order of more gallon cans. My main concern was to get the highly weathered edges coated as quickly as possible, and I did complete that project before my father became ill with bladder cancer and my time was invested in caring for him in my home, and then in a nearby long term home before his death in November. Now I am again undertaking the challenge of working on the roof. I am about to order 5 gallon buckets to cover the entire surface. I still have to ascertain how to get the heavy buckets up to the roof but shall find a process eventually. I took these photos of the motor home before and after as your website offered a monetary discount for sending in pictures. I see that it now has changed to video. However, I was glad that I did take the before and after pictures and I could not resist sending these photos anyway, with the tale of the lady and what seems to you a small and simple project, but what seems to me a completely intimidating and overwhelming project that I am able to complete because of the easy application and wonderful leveling aspect of your fantastic product Liquid Rubber! Thank you!

It was the best product I have ever used on my camper roof.
It worked out great!
