My question is I am bidding a 95 unit apartment comlex. They are two story, four unit buildings, I will be spraying elastomeric at a mil thickness of 15-20 mil. It will be of of latters, one person spraying and one backrolling. Does any one have passed experience with this production rate. I am thinking 500-600 sq ft per hour. My guys can push the limits, they are go getters. Any advice ?
