I'm currently waiting on my Wolverine order to get here to Calgary to coat my VCT black/white checkered pattern with some Bondtite....my garage use is for running my snowmobile in and out a daily driver large SUV. I will be posting a full description with pics of the install beginning to end. Hoping for some protection from the snowmobile carbides on the skis from the bondtite....we will see how it works out, durability is what I'm concerned about from the carbides tearing it up (I may have to invest in a full size sled dolly or just remove carbides before moving it around in there).
Bondtite epoxy coated vct will be water proof and your tiles should be fine with snow melt water sitting on the surface, however, if you have some water under the slab or moisture in the concrete, then maybe you'd have issues. I will post what I find out from my install once it is complete and I have some winter experience with the epoxy finished VCT floor.
