Can I paint my osb shed floor straight with this

Is says they should be laid print side down, painted using oil based paints.

 

What? you reading the same post Jit?

 

As its an OSB floor, a primer like Zinsser Bullseye wouldn't be a bad idea to seal it first or thin the first coat of the floor paint and use that as the primer.

 

Yeah, thin with white spirit, the Bullseye is a High Adhesion Primer and binds the surface together on drying unlike Leyland Primer/undercoat which I don't feel would be tough enough. Myself I would use the Bullseye, although KIAB may disagree as he promotes the Everbuild sealer (406 I think), never used it so can't comment if it's suitable for use on timber.

 

Would have put down a timber floor much better than osb.
