So I have been hearing great things about Black Jack Rubr-Coat No. 57. I want to use this on the inside floor of my coop, and plan on painting it on about a foot up the walls from the floor as well. I am hoping that it won't get tacky when the weather gets hot, but I have read posts from people who say it won't. I had a couple of other questions for those who have used it before though. - Can this be used to paint the roof instead of using shingles or some other type of roofing material? I plan on having a slanted plywood panel roof. - How many coats were necessary for adequate weatherproofing and coverage? I want to be sure I get enough since I will most likely have to order it online. First time using this product, so any tips would be welcome! Thanks!! And just to make sure I have the exact right type, I have included a pic of the can.
