Check out garagejournal.com. Lots of info on flooring. See the forums.

Many thanks PPF. Will do.

Vinyl (not glued down) can work in a garage CONVERSION. Just be aware that garage concrete slabs do NOT have the same moisture mitigation system used underneath a house. That means the slab is sitting directly over top of damp earth. The dampness will move through the slab and into the garage itself. This makes for problems when GLUING anything down (glue failure can happen quite quickly).

If you are keeping this as a CAR garage (as in you will park the cars directly over the floor), then you will want to know that the RUBBER of the tires can and WILL discolour the vinyl. And it can do it quickly. These stains are permanent. They will be the colour of orange/brown 'nicotine' stains (like you would see on the fingers of a heavy smoker).

It all depends on what you want to use the garage/floor for.

SJ McCarthy, this is for our car garage attached to the house. Thank you for the information, it's very helpful.

I had a friend who drywalled and painted her garage walls, and put vinyl tiles on the floor - she wanted her garage to look pretty. Well, several scrapes on the walls later (ladders, tools, the car) and water and oil leaks, and the place looked...well...like a garage!

Don't use vinyl. Epoxy is a better option for car tires. It won't stain.

A professional epoxy installer can deal with any problem the slab will throw at them. You can get a decent "garage grade" epoxy floor for $5-$7/sf....depending on the colour/slip surface you are looking for.

Personally if the floor is going to be used for cars, a sealed concrete (epoxy sealed) is the best possible option = $5/sf by a professional.

SJ McCarthy, we will consider epoxy, although I was trying to avoid muratic acid being used because of landscaping.

The website from PPF has rubber products, so another consideration.

How did we ever survive without the Internet! Thanks everyone.

Just to be clear, I was referencing the Garage Journal Flooring Forum

Formula car garages use porcelain tiles. And you could eat off of them.

WITH would you want vinyl tile on the garage floor?????????? It makes NO sense. That's where the Veh. are parked!!!!! NOT in you're living room!!!!!!

Garages do not have a moisture barrier within their slab. Glue down vinyl will come up over time due to moisture in the concrete. An interlocking vinyl could be damaged due to the weight the vehicles and if the tires are being turned back and forth -- This motion will destroy the end joints.
You're best bet would be porcelain tile.

Cinar, thank you but we have decided on epoxy paint.

The problem with epoxy paint is the heat from the tires. As you drive around, your tires heat up. You park in the garage and the epoxy paint will begin to peel due to the heat from the tires.

Homechef, thanks. My neighbors garage floor was painted when the house was built about six years ago and other than tire marks it looks ok. (I'll keep searching!)
