Garage Floor PU Paint

[JoelC]

Hi All,

I started painting the garage floor last week. I'm about 50% done, but there are a couple of patches where something had spilled on the concrete - I guess oil.

I had degreased and pressure washed the floor before I started, however this patch seems to have not dried, and is still tacky, even after a week. There looks to be similar stains on the rest of the floor, and I'm a little hesitant to do the rest until I can ensure a decent finish.

So, couple of questions,

1) what should I do with the patch that's still sticky - will heat help?
2) What can I clean the rest with to make it stick properly.

Ta

Joel

Try thinners or brake cleaner to degrease the concrete. You may have to use a sealing type paint first if you cannot get the oil marks off.

For the patch you're trying to dry, give it a little more time yet. Winter is a bad time to paint floors. If that fails, scrape it up and repaint.
