With your mom at a nice seafood dinner
So we did the inspection on our new house on Thursday. Everything is looking good except for the A/C unit not working. I was able to get into the outside shop for the first time. It looks like the PO poured the floor himself and used a 2' screed board on a 25' floor. I guess I could just go with it but I'd like something a little smoother.

I've asked a couple of people and I'm hearing that I should just jackhammer it up and start over. The leveling compound is retardedly expensive for the small area it covers. Do any of you have suggestions?

This.

For the floor coating, don't just get a heavy paint, do a 2 part epoxy floor coating. MUCH more durable. Make sure the floor is clean and degreased first, though.

I used to sell the stuff when I worked for my ex-in-laws. Stuff they made was for shop floors. when mixed, the stuff would generate some heat to cure. Have to work fast to apply. Had one guy mix up a 5 gallon bucket and get distracted by a phone call. By the time he got back, the bucket was melting and smoke was pouring out.

X3, if you don't need it perfectly level. It would smooth the surface out, but I suspect the are high and low areas too.

I thought this was for more minor imperfections and to remove adhesives. I've never ran one before but this is what I've read.
 
It will remove as much as you are willing to hold it for. You might still have an unlevel floor but most slabs are unlevel. But you could have a smooth ready for floor coating surface. I've spent many hours on one In a commercial garage removing 50 years of abuse and grease. You can get to clean/smooth concrete pretty quick. Figure a full day grinding to get it just right. Get a shop vac with a debris bag, Not just a filter. The filter will clog every 5 minutes. The bag will go till full. Don't use regular paint. It will stick to the first vehicle tire that gets parked there for any amount of time and peel up.

No offense, but don't do this. Concrete doesn't adhere to concrete. It will start popping up almost immediately.

That was my concern and the reason for the question mark.

It is a common process in the stamping industry from what I have seen/heard.

Hell yeah, that sounds good. Once we move in I'll definitely check it out. Thanks!

Just know that you can't weld on an epoxy floor.

Well, you can, but it'll burn and come up.
 
Personally I would grind it down close to level. Got real aggressive at first with a 20grit diamond and when you get where you want, work your way to 100grit. Then put a good densifier in it like Euclid Diamond Hard. That will make it dust proof, easier to clean, harder, and get shinier over time. Then you can weld, drag stuff across it, spill oil on it and clean it right off.
Only other option is a self leveling bag mix. But they cost roughly $27 per bag +\- and don’t give a lot of coverage. You’d still have to get the floor to a rough profile for that mix to bond to. Then you’d have places that ran to what we call a “feather edge” which is not good for a wearing surface.
Shawn is right, if you plan to work on a floor like weld and drag metal things across epoxy is a no go.

Is that the ritzy side? LOL them folks got a surprise heading their way. My neighbors are looking old and uppity. I can't wait till I roll up with the Jeep.

It seems like the ritzy side moves around. When I was younger, all the town big wigs lived down by the river in Ridgefields, then for a while Boone’s Creek was the hot place. Now, it seems like most of the movers and shakers are moving to the Orebank side of town.

So, I've got a 20'x25' concrete pad freshly poured, about 6 weeks ago now. I'm about to put a metal building on it and was then going to epoxy the floor. I will likely be working on vehicles in it and that may include welding. Would it suffice to cover the floor with fire blankets or should I use a different floor coating?

I wouldn't do shit to it. I would have had it trowled smooth, then nothing. If it's not smooth, I'd have it ground smooth.
