No idea about the cost of it, though., I just mess with the regular stuff.

    There are also floor leveling mixes that would work. Self levelers like Ardex might work.
    When we or rather when I had my floor done, they used mesh for the reinforcement (rebar) and poured about 3 inches worth on top of roof paper and 4 mil plastic. The entire cost was $1700.00! I don't know how much it is there, but here So. Cal anything else would have been a lot more and not as good. We have dropped 50 to 100 pounds of material and very, very little damage. And if there is any damage you simply rough it up and pour patch. But we have not had to do any repairs as of date (we have a good sub-floor). I think we can all agree that a concrete floor is the best flooring to use for its fire resistance, sound, solid properties and ease of maintenance. Tile seems as if it would crack, Gypsum board (Wonder board) would also crack and the self leveling goo I've seen would shrink, crack and later peel. At least this has been my experience, but what do I know (know that's a good question)....(:

    I don't see that hurting a thing...sort'a like being on a ship or a truck or any other piece of big equipment. People do it every day. I would be more worried about slipping and busting my @$$. Thats why I suggested tread plate...It's designed to be used for a floor. I'm sure 20 gauge would work tho.

    Default Thanks, FusionKing

    I'll check the price of the lightest tread plate. Maybe it's in the ballpark.

    When I have needed to torch or plasma cut something that was real close to the floor, I just dump a few scoops of oil dry under my cutting area and it keeps the concrete from popping out from the heat. Obviously, it wouldn't be very practical for a whole shop, but it works great in spot applications. No matter what you do I'd make sure and have a couple of really good extinguishers on hand at all time. Murphy loves to show up when welding and I'm sure he'd love a wood floor. Especially when a mass of slag finds what was left of the quart of oil that was spilled three weeks prior and soaked under the tread plate to saturated the subfloor

    heres what i learned when i was a machinist mate in the us navy. You can use a metal floor just fine if you worried bout grounding out do this get a rubber mat and sit your stool on it or stand on it or whatever problem solved thats what we do at work.

    JCB, I have been looking through our files and I cant find anything on those floors I was telling you about. My boss is on vacation but he comes back on Monday. I'll see if he remembers what it is called or if he has any info on it. Sticks in my mind it was some kind of epoxy mix they sprayed on.

    What else is there besides welding and riding. Besides that

    Thanks KBar,

    I've seen some of those epoxy finishes. They appear to be very durable. Are you saying that these type of finishes on plywood could withstand welding over them ? If so, this would be ideal, especially if pooring some type of concrete is the only othe logical option.
