difficulty rating is a 3 out of 10. really easy to follow instructions. only advise id give is make sure you don't spray too close to the floor to avoid puddling. directions say 10" from ground. I should have read that part. but after the first pass you get used to the spraying and it's real easy. just takes time waiting for it to dry completely. most important part is the prep work. make sure you scrub and clean the cement before use. I had a pressure washer and made the prep real easy. kit comes with the cleaner you mix with water and that shit is strong. looks like acid when you poor it on the cement. white and foamy stuff
