Liquid Roof application

My neighbor and I did a 30 ft MH rubber roof several years ago. Did not need primer. He cut in along the edges with a brush and I did the top. Did not need tape. I had a hard time rolling the liquid rubber and spread it with a squeegee and brush. A 5 gallon pail was more than enough for 30ft. (34ft you may need 6gl) After about 4-5 hours the material was definitely getting thicker. Mixing 1/2 at a time would also allow you to quit for the day and continue later.
One unexpected result was the roof wrinkled and had some bubbles the next morning. But these totally went away over the next few days. Roof looked good, was durable and trouble free.
