I have received a lot of good info off of this site but haven't contributed much. I thought I would share a recent roof job I did using DuckCoat roof coating, www.duckcoat.com, I purchased from Menards. I could not find much info about this product other than what is on the website. The product said it was safe for EPDM rubber. I emailed the company. I was told this was a solvent based "rubber friendly" product. I sent pictures and was told this was the right product for the job, but it must go on in 3 coats. The first light coat acts as a primer while the coating "bites" into the EPDM membrane. The primer coat is followed by two heavier coats. I purchased a 5 gallon bucket for $175, three 3/4 nap rollers and a couple brushes.
As you can see in the pictures my roof was in bad shape. Someone at some time had rolled something on it. It wasn't leaking but the top white layer was cracking and the black was showing through. This is on a 1995 Damon escaper. I felt like at less than $200 I would give this product a try. Worst case scenario, I would put a new roof on it this winter.

I started Friday evening by pressure washing my roof off and cleaning it with Dawn dish soap and a broom. I let it set over night and did the same thing again Saturday morning. I then let it sit for 24 hours to dry.
Sunday morning I ran masking tape down the edge of the gutter down the side.
I then set out to mix up the product using a metal stir attachment on my cordless drill.
I started out by brushing a light primer coat on both sides where the roof rolls over down the side.
I then trimmed around all my vents, AC, antennae, railing, etc. I did remove the AC cover and the fridge vent cover. My caulking was pretty good around everything, only a few hairline cracks. I was told by the company that the DuckCoat would seal them up too.
After everything was trimmed I rolled on the first primer coat on the roof. It says to put this on at a rate of 1/2 gallon per 100 square feet.
I let it sit for 8 hours and rolled on the second coat. The second and third coats go on at a rate of 1 gallon per 100 square feet.
I am going to do a third coat but have not yet put it on. I did get a little wrinkling of the membrane after the 2nd coat in a few places where the membrane was not glued down the best. I understand people have this same thing happen with products like liquid rubber but they usually go away. After a few days these wrinkles went away as the product cured. Your results may vary but overall I am happy with the outcome for $175. Time will tell how it holds up but I am confident it will work well. The only downfall is having to put it on in 3 coats. However, it goes on easy.
If you have any other question feel free to ask. I appreciate all the help I get off this forum and hope you can benefit from this.
