After floor scraping there is still the grey stain in the osb board. Skim coat residue.

How do you get it off?...............Wash it with a scrubbing brush and quickly dry?..................Floor sanding machine?

I tried wire brushing it but it still remains.

Dunno will give it a try. It will be the finished floor with no finish on it so I dont want plaster dust coming off it in the future. Its not a house.

Why are you asking? Seems strange that OSB would need to be spot (stain) less, and if it did, why wasn't it covered before you plastered?

What so OSB is being used as a finished floor? That's got to be a first? Could possibly look effective if treated right.

Because its not a house/home. its only the mrs studio and storage and will get minimum traffic from her hooves.

In total it is 700sq ft. it would cost a fortune to cover it with a floor of some kind.

Should scrub clean. Worst case, just replace the osb.

Paint it. Is the underside of the OSB exposed, or over grass or something. If so, it’s not going to last very long.
