I have VCT and I love it so far. I was able to find all of the tile on craigslist, new in boxes, from two different sellers.
I did around 840 square feet for less than $300. And I have plenty left over for eventual repairs.
Also, Lowes or Home Depot both have this tile available at their special order desks and will get it for you. Before I found mine on craigslist, I checked and both of them had the same pricing on it.
I have no illusions about this material holding up as well as a 100% solids epoxy floor. But, it's certainly good enough for me. It's easy enough to sweep and occasionally mop clean. It seems to take quite a bit of abuse without issue. I have car dollies and engine stands on it all the time.
I used Armstrong Imperial Texture series tiles in gray, white, and black. Contrary to the name, it has no texture. Adhesive used was Henry 430 from Lowes, a local tile guy recommended it. I got the Henry 430 from Lowes and put it down with the trowel that was recommended on the bucket of adhesive, I think it was 1/16" rounded notch.
Prep was to vacuum, damp mop, vacuum again.
You lay down the glue w/trowel and then wait for it to "dry" to a translucent yellow (about 30 min) then you start laying tile. The tile sticks like mad to the adhesive, so you need to be careful and take your time laying them down.
It is also easy, if a bit time consuming, to do some custom designs using VCT tile....When doing so, the table saw is your best friend.
