I have had experience doing garage floors etc before.
HEALTH WARNING - read the instructions and wear the CORRECT face mask or you will get very very very sick cause the fumes are leathal. I can speak from experience cause I thought i would be like superman and not read the instructions about the nasty chemicals and I found myself in hospital very very unwell a few years back.Make sure you let no-one watch you painting, not even for 5 minutes without thye correct face mask.
Hope It helps.
