Ron,
Thanks for the update and good words. I guess I'll owe you a dinner!
To help protect the floor from sharp jack stands, you can also just order a couple of extra tiles and use them as a sacrificial tile under the stands.
As a note: I have had a 6,000 lb delivery van loaded with heavy flooring jacked up on one side and a single stand placed under the frame on top of the flooring with only a minor nick left from the stand. That same weight would have definitely left a mark on any other type of floor coating too.
Terry,
Typically, our first time customers installing their own floors usually take about 6-8 hours for a 2 car garage. The second time will cut that install time in half....I can do a typical 2 car with 2 colors in 3 hours. (Of course, I've installed about 100 floors myself so I've been practicing!)
