Hi - this is my first post so please be patient with me. I have a 52 X 24 garage that has a coat of rustoleum epoxy in gray semi-gloss. The previous owner mixed no slip sand with the paint so the surface would be rough to prevent slipping. Now, many years later the epoxy is peeling and delaminating badly in several areas. In some areas it seems to be ok but the floor looks bad as is. If I decide to put down epoxy again - what must I do with the existing finish? How about if I decide to scrap the painting and go with the portable 12" X 12" floor tiles. Is this stuff worth the money? What's the best solution?

Epoxy Problems - Should I repaint or tile?

I was facing a somewhat similar problem--my garage has an existing H&C sealer on it. It's still bonded pretty well but for me to spend $1k on epoxy in materials alone, I would have to spend a weekend grinding down the old finish just to be sure. That's why I'm going with porcelain tile.
I was thinking about the plastic tiles that can be removed...like the stuff Gladiator makes... Can you share more on porcelin tile? Can it handle weight from heavy trucks and boats? Cost? Is it different than ceramic tile? What about oil/chemical spills?
I can't find the thread... Can Your Garage Do This.....but I'm liking the idea of cermaic tile...for one..it's less expensive than the portable tiles..but I have so many questions..
My epoxy finish is a mess, delaminating etc...I don't want to strip or grind it all off..Can I mortar over the bad epoxy layer?
I have a couple 5000 pound boats..will the tiles crack?
What about oil spills on grout..seems like this could be a mess?
Do I need to use a specific size?
What should I be looking for? Do's? Don'ts?
What type of mortar? What type of grout?
I would appreciate any help you can provide or point me to the right section on this website....Thanks in advance...

Never coat over paint ( h&c).
Epoxy that is down tight and not delaminating can be gone over.
In your case, it's a grind. Anything else is a dice roll.

Paint is absolutely the worse thing to apply to concrete. Paint is film forming and does not penetrate the concrete. All concrete has constant moisture traveling through it and causes the paint to depart the surface.
Just Remember, anything that is applied over the existing topical coating is only as good what you are going over. Scotty failed to mention if going over an existing epoxy application you must first remove any floor finishes, waxes and then degloss the existing epoxy. This is achieved by sanding the surface. My installers use an 80 grit sandpaper on a large vibrating parquet floor sander. These machines can be rented from most rental companies. This creates a rough texture on the surface (scratches) so the new epoxy coating can adhere to. Not doing this will cause a poor surface adhesion.

Yes, degrease, degloss, solvent wipe and reapply.

Right back at ya scotty. Xylene isn't good to use as a solvent wipe.... just a FYI. The manufactures of xylene are starting to use "reconditioned" xylene and it's still dirty, often containing stuff that can effect epoxy laying down smoothly. Also, the EPA is cracking down on it's use. State by state the VOC laws are a changing. Ohio is cracking down pretty hard, Indiana has laws in effect but the hammer hasn't been swinging too hard yet. I'm a big fan of denatured alcohol as it's still OK to use. As with any combustible please read up about its use and take heed to them. Xylene is lighter than air and when it reaches a certain % level floating up on the ceiling, static can ignite it. PLENTY of air movement is the key with the use of any volatile.
