Staining Particle Board Flooring

I've wondered if I could tear up my carpet and use the subfloor but I was thinking of painting, like a high gloss paint. Has anyone tried that?

i plan on doing the same thing when i empty the room of current furniture. i saw it on hgtv several months ago. maybe search it there. my plan is to steam clean it with a steamer then sand it wherre it needs it. then put a light color stain on and wipe it off. i plan on sealing it with a clear sealer.

Just be aware that particle board comes in 4x8' sheets that aren't centered (so you don't know where the ends are) and the ends soak up stain differently than the center, so the seams will be visible. You may want to seal them too.
