Painting OSB3 boards

[paulm]

Not exactly fine woodworking :lol: but about to start boarding out the inside of my refurbed shed come makeshift workshop with OSB3 boards, which are the ones with a high glue content that makes them half way decent as a vapour barrier to keep the insulation layer behind them dry.

I was wanting to paint them white afterwards to improve the light levels in the workshop and if OSB2 would just do a couple of coats of emulsion, but the higher glue content and shiny/waxy surface on the OSB3 makes me suspect that may not work too well ?

Any experience or suggestions appreciated ?

Thanks, Paul

It'll be fine - obviously a silk will give a bit more light refraction than a matt.
