On the subject of finding good contractors or more accuratly getting your money's worth out of them. A developer recently bought several acres accross the road from me. They have been doing dirt work and surveying over the last month while the wife and I watch from our deck. Workers routinly arrive at 7am,work for 30 minutes,a truck leaves then returns with snacks and drinks. 45 minutes to 1.5 hrs are spent consuming snacks before about half of workers return to the machines which were idleing the whole time. Work continues for another hour before they stop one by one and sit for an hour or two while drivers nap in the air conditioned cabs. The routine is repeated every day. Mind you this developer has been around for years and has multiple jobs underway at any given time. If an experienced company can't find good help,what are the odds for homeowners?

I'm sorry but there isn't an easy answer to this. Cars are heavy and their tires are made of rubber. A dance floor will have to be "sprung" (some can be as high as 2 feet off the ground when properly constructed....using horse hair). Once "sprung" a floor like this should NOT be sitting underneath 2 tonnes of automobile (the "sprung" gets crushed and you end up with expensive yet damaged dance floor = useless). Then there is the damage the rubber in the tires will do to ANY finish that is sitting on the floor. Rubber damages just about everything out there. The only thing I would put underneath rubber = concrete, dirt, stone or in a pinch epoxy. You will notice that none of those are good for dance. It would be cheaper to "build out" the garage as a dance studio and then park on the street or in the driveway. That's about the only way the two will work together. The other option: a professionally designed and constructed "temporary" floor (like the one's you see on TV being used for professional basketball courts). These floors are designed to be removed (by a crew of 15-20 people) after each set of games (teams go on the road and the facility is used for trade shows, beauty pageants, etc). They are expensive to design, expensive to install, expensive to maintain and physically very hard to remove/replace using one set of hands....or even 3 sets of hands. It would be financially easier to deal with if you did an addition to the home. It would cost less than one of these floors.

Here are a couple of option. Of course the choice depends on style of the room: Option 1 https://www.homedepot.com/p/Armstrong-CushionStep-Better-with-Diamond-10-Tech-12-ft-Width-x-Custom-Length-Marble-Onyx-Residential-Vinyl-Sheet-Flooring-B3365401/307994562?mtc=Shopping-VF-F_D23-G-D23-23_4_VINYL_FLOORING-Multi-NA-Feed-PLA-NA-NA-Armstrong&cm_mmc=Shopping-VF-F_D23-G-D23-23_4_VINYL_FLOORING-Multi-NA-Feed-PLA-NA-NA-Armstrong-71700000066292651-58700005841957879-92700053363622973&gclid=CjwKCAjwh472BRAGEiwAvHVfGr3ALqzXzpDfk1BrYfGHL0eX7X9bgIN34Dx2NTOLtOk4dSSmQWYH_xoCEZsQAvD_BwE&gclsrc=aw.ds Option 2 https://www.houzz.com/products/12x24-universe-matte-modern-tile-prvw-vr~121974018 Option 3 https://www.houzz.com/products/black-oak-12x24-polished-marble-prvw-vr~45131025 Hope this helps!

cpartist is on top of this one. It is hard for us to tell you about your own tolerance levels. It is a personal choice. Marble can last for hundreds or thousands of years (depending on how thick it is). It won't look the same as it did on day one. In fact it will look different on day 2 than it did on day 1. And day 3 will look different than on day 2...etc. Marble can be made a bit less likely to stain and etch by using stone sealants. The installer will apply the sealant twice prior to the installation and then once more before they grout. These are all extras you can pay for...so long as your contract specifies it. These sealants need to be renewed periodically. Depending on the product used it can be as little as 6 months or as long as a decade. Stone is fantastic for longevity but it does take a certain personality to 'handle' the living finish. I love marble. Love it! I don't mind stains (because my house keeping skills are non-existent so I have to live with my own level of inertia). The etching eventually evens out (over a few years). Before that time it looks splotchy...but then again I don't care so 'whatever'. You need to understand your own reaction to products that change. Their perfection comes because of their IMPERFECTIONS. You need to love the CHANGE before it even happens. If you need perfection then porcelain tile is the way to go.
