I also used Innovative Concrete Coatings 1.5 years ago. Excellent installation and result: they stayed until 8 pm to finish the job because there was a skim coat of cement on the floor the at took 4 hours to remove (instead of the usual 2 hours). Surface is not slippery. Pictures of the work, at my house, is posted in this forum at:
Our Team Is At It Again!
Lesson learned: expensive, but you get what you pay for (and I received an excellent result).
