I have to remove old paint from a concrete floor

Do you guys have any experience doing this. Its in our kitchen that gets state and federal inspections. They are recommending an epoxy coating such as used on garage floors. I think the old paint is oil based. Thanks guys.

when we did our hanger floor we sand blasted and acid etched the floor. that wast the prep requied by the manufacture for the floor coating we were installing.

You can use a floor buffer with a grit pad to remove paint - 
On a concrete floor that had carpet on it I removed carpet with a razor knife blade on wheels witch cut a 10" swath of carpet , but the glue used I found out was called Green Death - it resisted every try to remove - found a orange based solvent I had to swab over area then use razor knife again to remove the residue . 
 paint sounds easy ! 

We had a similar problem with the floor in the wife's bakery, it used to be the old Ford Garage and I believe part of the older Caterpillar and John Deere dealership. Somebody poured a cap of very low quality cement about 1/2 inch thick and then painted it with who knows what, well the cap will lift in places and the paint lifts in others, I repaired the places where the cap came up but the paint is resitant to every kind of floor sander that I tried, the only thing that will touch it is a hand grinder. So there is not much we can do but coat the floor and then repair the little spots, I wasn't going to jackhammer out the cap and repour it in a rented building. I can say that the Rustoleum Garage Floor Epoxy is very tough stuff, we didn't put in the sprinkles, but the floor has a beautiful gloss and it is tough as nails, it has lifted in several spots, so I had polyurethane paint mixed the same color to repair where needed, probably the best option until the floor is replaced. The one thing about the Rustoleum Epoxy is to be sure and mix it according to instructions or there will be a color change between containers, but I still highly recommend it.

Just finished quoting refinishing our existing hangar floor which is 22 years old and finishing the floor in our new addition. We use the floor hard with a lot of traffic and maintenance chemicals and the rust oleum epoxy has done well. We’re going with a multilayer Tennant coating this time to get the high gloss with anti skid for customer safety. In either case the only way to apply epoxy is on bare concrete. Both new concrete and old finished concrete have to be prepped. It can be ground but we’re having it blasted. It is actually shot blasting with steel shot not sand. The cleanup is pretty easy because the equipment has dust collection then you go over it with a magnet to pickup any stray shot and finish with a shop vac for any dust left on the floor.

shameless, i don't remember. Its got a seal coat over the top of it. That stuff is coming off. Son brought over a machine to remove paint from cement floors. I ordered some 20 pads for it and bought some paint remover. We're gonna work on it next Monday.

still kinda weird to me that you couldn't just go over the top with something new!

Got the dang 2 part epoxy down today. Waiting to see if it needs a coat of clear over the top of it. This stuff came in 2 one gallon cans in a box along with colorful sprinkles. I can assure everyone, if I had to buy this stuff again, I will take it outta the box and have them shake it up, especially compound B. Was it a job. Will get you high as an eagle in flight. Even with windows open it was stinky.
