Anyone try it successfully on a floor? Would you do it again, do you regret it? We also have that clearance going on & I'd love to re-do our ugly 30 yr old beige scuffed kitchen floor. However, since it's a floor, I'm scared I'll try it only to have it crack, not sit flat, etc. We'd have to scrape up all the old stuff so I would think it'd be flat since we don't have any issues now. However, I'm still nervous to try. We could also try for just a small bath. That ($*$()$&$ tile is in all the baths too. Just curious what type of experience anyone's had as a DIY project. Or is it worth it to just pay someone? If so, how much did you pay? Thanks!!
