The stained concrete floors didn't come out as well as I had hoped. Instead of using an acid based stain I tried the 'Green Building' friendly soy based stain. However I had kept the floors protected with building paper and plywood up to now and when we removed these materials the floor was still wet. Steve Ramirez and his crew powerwashed and applied an etching product which is supposed to 'open up' the concrete. While the surface dried out the soy stain did not penetrate deeply into the concrete. Even a week later the stain was still sticky and after applying the sealer moisture began to build up underneath. So Steve stripped everything off waited a few days and reapplied, this time more lightly which was too bad as it didn't create as nice as an effect.

First application of stain
Applying stain
Buffing the stain into the concrete (we should have known there was going to be a problem as we went through ten or more of these polishing pads)
Five days later the darker color of the stain was still not dry. Here Steve applies caulking into the score pattern - this too was not a good idea, we ended up digging out the caulking and applying grout.
