New to site, great stuff. I'm building a shop this summer and was going to color my concrete but wondering if epoxy coating is a better choice? I do lots of welding, cutting and grinding, in hafe the shop. The other hafe is just parking. Would like to make the parking spots nicer. Any ideas!

Overkill give em some time I know some have although that is one of the biggest reasons I still have bare concrete . I do way to much fab work to trust about any floor covering to hold up.

The weld slag and grinding debris will melt through the epoxy. This is why i chose not to go the epoxy route. Clean smooth bare concrete it is for me.

What about putting a welding blanket on the floor around the area where the welding happens? My floor was too disgusting not to cover up, and I went epoxy...

I plan to have a nice Epoxy Floor inside the shop and plan to weld outside thru an 8' door. Anything that generates a bunch of slag, sawdust, wood chips, metalic dust I plan on going outside and down-wind.

Try epoxy on the parking half of the shop and concrete stain on the remainder. Give a good "break line" between the two areas. Try adding an accent stripe between the two or frame both areas with an accent stripe in epoxy. I have a friend that finished his this way and does not worry about the weld slag on his floor.

If is does get messed up, another coat of stain, a little sealer and he is good to go for a few years. His choice was a bright white epoxy for the parking area (no chips) as he worked there and wanted the "clean" look to help in lighting and to find small parts that get dropped (this is also his light work/assembly area). The "heavy work" side (welding. grinding, cutting, etc.) was stained a dark brown. He used a dark green accent stipe around the white to set things off.

It has been a few years since I was back in that area but he claims the floor still looks great.

Edit: One thing that I did not mention. He needed to add lights over the stained area as it looked like a cave compared to the other side with the dark floor.

There have been many posts previously on this. I have read as many as I could because I plan on doing my floor this summer. I also own a MIG welder with plans to acquire more welding equipment in the future.

http://www.garagejournal.com/forum/showthread.php?t=21928&highlight=epoxy+floor

That thread has some good information at the bottom of it. I really like Vicegrips garage as he does alot of the work I hope to do in mine someday. He just used the cheap water based epoxy. Many have mentioned that if you use the proper floor prep the water based works fine, as long as you do not plan on using your garage as a show place.

For me I just want to eliminate concrete dust and make it easier to clean spills. The fact that the floor should look a little "prettier" is a nice bonus.

I believe Wolverine Coatings also has mentioned they make a product that should hold up to wear and tear of welding/fab work. But as of yet I have not seen anyone use it on this board and show results.

A quick search should yield several threads that deal with using an epoxy floor and welding.

I think I will color my concret when pouring on the one hafe and epoxy the parking side. Has anyone tried different colors on the same floor. Maybe a border of some sort would look cool!

No epoxy floor coating would ever hold up to the abuse I would put it through. I don't see how epoxy would hold up in a "real" garage.

Overkill I would say if you are looking at colored concrete I would do the whole palce that way and not have to worry about the floor other than maybe a good clear epoxy just to keep the dust down.

It's hard to weld outside with any gas shielded process. Even a small wind can disturb the gas coming out of the torch/gun. You need to set up barriers to block all wind. A lot of folks stick with using flux core wire when they need to weld outside, but I have a hard time matching the results I can get with gas.

And if you think welding slag is tough on epoxy floors, wait till you see what it will do to an asphault driveway! And plasma cutter slag makes even more of a mess than welding.

I weld pretty often and my epoxy has held up pretty well. A big chunk of slag will make a tiny burn mark but overall welding hasn't done much damage.

We do make products that are used in welding areas of shops. In fact, if you have a Buttler building then maybe it was made on one of those floors. Fred has been chompin' at the bit to sell these products but I am concerned about the DIY installation.

What concerns do you have?

do a basic concrete grind to make the floor somewhat smooth, stain the floor and seal it with something that will get inti the pores to avoid it adsorbing an oil spill or something like that.

it will be smooth so it will be easy to sweep up
it cant peel up because the color is in the concrete

I would be interested in this as well.

I've had a few conversations with fred and I'm going to to be purchasing this summer as well. welding/plasma vs the floor has been my #1 concern since thats about 75% of what I do.

I'm also interested in this. What concerns you about DIY installation? does it require extra preparation? difficult to work with? produces noxious fumes? extra-short pot life?

If your going to pour a brand new floor. I would just get the color you want mixed into it and never have to worry about it again.

I guess Wolverine is not going to tell us why they're concerned about DIY installation of this particular product. Too bad, i think a lot of us would love to have an epoxy floor that would stand up to welding slag.

I have an epoxy floor, I weld and grind over it all the time. It has some spots in it from welding on chassis and exhaust systems - so what. Still looks 100x better than bare or sealed concrete to me. It's also got rubber, car paint overspray, dings from schooching engine blocks around, dropping heavy stuff, etc on it. But it cleans easy and spills wipe right up - it's a working floor, which is what I wanted.
