Its just like a can of paint. You get it in a gallon paint container, it is really thick and gritty. I used a roller and dumped a bunch on the floor and just spread it out. waited a few hours to dry, and did the same thing over again. Each coat gets thicker, it just depends on how thick you want it. I may go back over it again this year and add another gallon. it was $75 gallon, but i did the entire floor/walls with one gallons and did two coats ($150). It is also nontoxic to the birds. It is scratchproof. If you look at most of the trucks nowdays they have the spray on bed liner (we did four trucks with it and used the paint brush/roller instead of the sprayer. dont know why really, we have a sprayer and it worked just fine.
I am really thrilled with it. I was able to do it myslef, DH got out of doing more labor. It was cheaper for me, as i had used backer board on my walls and didnt want to redo them. The only thing I did NOT like was that I did not coat the walls high enough for ducks. It was great for my chickens, but i would do it at least two feet up with ducks they way they fling stuff.
