Hello, all. New to the forum but have some good experience with plastic floor tiles. I have used RaceDeck in two shops. Each about 1200 sq ft. I would certainly do it again. Advantages on an old garage floor, you do not have to take up the old coating if there is some, do not have to do more than mop up any loose oil and grease, sweep it out and you are good to go. No contractor, just you and a rubber hammer. You can do 1200 sq ft in about 3 hours or less if you are younger than me and if the garage is empty. This stuff is bullet proof. Will not crack no matter what you drop on it. It is easy to replace if you were to some how ruin it. I really like this stuff. Yes, it is noisy to walk on but the benefits way out weight the negatives. It is pretty well sealed in the joints so there is little if any leakage under the tiles if you wipe it up. It is very clean to work with after installation. You can hit heavy grease with brake clean and it is like new. It insulates the floor in cold weather. Plus, it is portable - you could take it with you to your new digs if you move. It was especially good for me because both shops had old epoxy floor coating which had lifted over the years and was flaking off. I removed the loose stuff and laid in the new floor. Another advantage is that you can customize the colors. I have checker board gray and dark grey. Looks great. You can do it in sections. They advise to do it all at once in an empty space but that is not always possible. I had too much junk to move so did it in sections. The stuff is high density polyethylene, I believe and is really tough stuff. There are others on the market including Costco but they are not as tough in my opinion. RaceDeck is guaranteed and will replace tile if somehow they fail. Great service, as well. I have no connection with them other than being a satisfied customer.
