I've not used it but have had installers try it. I've also had the pleasure of grinding it off. It has a lot of silica fume in it to attempt to make it self level. It doesn't do that too well, even after gage raking it out. It comes out wavy and doesn't hold well on uneven surfaces. I can't vouch on how tough it is or how well it sticks or hold up to freeze thaw conditions. I would really suggest a rough surface to apply it on for hopes of it hanging around for awhile. Hopefully someone that has applied it can chime in and give the facts on ease of application and it's longevity.
