Question: How would I know if my roof is the ALFA brand or not. My 5th wheel is a avion and they haven't made these in several years.My 5th wheel is a 1995.
Document: I did what it said it would. It was easy to apply. It really makes the roof brand new. We should have used it sooner.
Actually this seems to be a good product, difficult to use and messy, and it seems the chemistry is there,  however beware if your rv roof is the ALPHA brand EDPM, as per the manufacture (Pro Coat) , there needs to be a primer installed, or the roof will fail in one to two years. THE EDPM rubbers are not compatible.
My '95 22foot Terry trailer has been sitting unused in the southern California sun for 5 years. When I decided to start camping again and was cleaning it up for the road, I noticed that the rubber roof membrane was in serious need of replacement. No one would even talk to me about repairing the roof for under $3000.00. Hell, the trailer isn't worth that much. I did a lot of research and read about &#34;LIQUID ROOF&#34;.
I bought liquid roof to stop leaks and recondition my travel trailer. This product exceeded my expectations. It was easy to install and cured into a brand new roof! I would highly recommend putting down the primer before instillation since I did have some spots not fully adhere to my existing roof. These spots were only quarter sized and did not effect the overall performance of the new roof.
We are not EPDM coatings and certainly would have advised you that the product does not work over ALPHA brand rubber roofs without a primer. We are Meridian Liquid Coatings.
My RV roof looks brand new and I couldn't be happier. Took about 3-4 hours to complete. Dealer wanted $1800 to do this job which was very easy for a do-it-yourself person.
I purchased and installed this last summer on my trailer. It has been on for a year now and after cleaning the roof it still looks great. I expect this to last for the rest of the life of my trailer. I would recommend this to anyone who is looking to restore the roof on their RV.
I thought this product was pricey but it really met my expectations. Creates a really tough, shiny membrane that seems way better than the cheaper roof coatings. My only complaint would be that it would be nice to have an easier way to use less than the whole batch at once. Still, one 5 gal container was more than enough to coat my 32 foot motor home and then go onto to additional areas on another older RV I own. So far, it seems to live up to the billing.
Put on the rv roof. It was very easy to apply, and looks great. I am very happy with this product.
In the process I was covered with BLACK RUBBER yuck as was the sides of the trailer and the driveway. These all cleaned up fine later on with a pressure washer and some elbow grease. I ordered a full 5 gallons of Liquid Roof to make sure I had enough. I followed the instructions on the label. I had watched a number of YouTube videos on applying the product and had a friend help me.
