Help!! Need to Remove Behr Acrylic to Put down Epoxy

[SeattleIS300]

My wife wanted to stain the garage floor so we went with some Behr stuff after cleaning,etching and apply 2 coats of stain she hates the way it looks and wants epoxy. So it's never even been driven on or used etc. I think we are lucky because we never sealed it with a top coat. I went over to lowers and boat some QuickCrete epoxy floor but i'm thinking UcoatIt is probally a better choice. What is the best way to prep the floor for epoxy? Should I use a EDCO floor grinder or just scuff the surface? The insturctions say to use TSP then Degloss and sand surface? Are the diamond blades overkill? Let me know.

Thanks

If it were me, I would go the Edco grinder route as you have no idea how good the bond is of the sealer you put down. The new epoxy will only be as good as the surface underneath it. Lots more work, yes, but worth it to me.

You say stain? So this wasn't the Behr 1-Part Epoxy Acrylic Concrete and Garage Floor Paint that HD sells. I picked up a brochure for that stuff today as well as the Rust-oleam, just curious if your bad experience was with the stuff spelled out above or a different stain.

I am looking in to UCoat-it. I also have something on the floor - eithe Behr Stain (likely) or Epoxy Acrylic concreate floor paint. The UCoat-it instructin Manual (on the website) says for previously coated concreate "scuff or sand the surface with a 6-80 grit sandpaper to prep surface for mechanical bond."
"Chemically clean, then rinse. Proceed with bond Coat and finish application"

They have a tech support/cust service # 800-826-2848. I plan on calling them after I figure out what other questions I have for them as well.

Using the Edco grinder is a sure way to remove just about anything and prepare the surface of the floor. They can be work using them, but they produce results. The diamond blades are the ONLY way to go! You may need to add weight to the grinder to help it bite in, just go slow and always keep the machine moving. I add a patio stone or cinder block sometimes. By grinding the surface you will open the pores of the floor and increase the surface area, causing you to use more product than an un-ground surface would need. Be sure the let the guys at UCoat It know that you ground the floor, you DO NOT want to run short of epoxy in the middle of the job. Buy more than your square foot measurement would indicate.
