Shooting paint with epoxy garage floors

Hi,

I've shot paint in my old garage several times. Epoxy primer, base and clear. When painting, the overspray would settle on top of everything as a fine layer of dust. The dust was not difficult to get off of the floor and other things it landed on. My garage floors were concrete and not coated with anything. I could just sweep and hose out the overspray dust after I was done.

In my new house, I've got epoxy floors in the garage. Yesterday I shot rustoleum (from the quart) thinned with Naptha from my HVLP gun. I was painting a bunk bed for my son. The paint job turned out great but the overspray adhered to the epoxy floor and was very difficult to get up. I had to use a combination of laquer thinner, scrubbing with a push broom and a power washer to get the floors clean... and they still didn't come out perfectly clean.

I'm a little bummed that I messed up my new epoxy garage floors :(

My question is this...

Did this happen because there is something different about the alkyd oil based paint (rustoleum)? I've never sprayed it before. Something is clearly different.

Or is the difference the epoxy floors? When I shoot epoxy primer and base and clear over the new floors, should I expect them to stick also and be difficult to get up? What do you guys experience when painting over epoxy garage floors?


Thanks!

My guess is the oil based paint...it can take days to cure if not activated...most primers and base coats are dry before they hit the floor...the old strait enamal auto paints we're terrible for making a mess
 
I have epoxy floors in my garage where I paint. I cover them completely with plastic sheeting. Just the cheap 1 mil stuff from Lowes. My work bench(mixing) area floor is not covered and the occasional drips I have to wipe up quickly with reducer, but the reducer will eat through the clearcoat epoxy on the floor, so I do a quick swipe just to get the pain off..
