    Folks,
    I have a small project, nearly finished...
    It's basically a small brick shed... I'm going to paint the inside, white, to help with lighting, so I'm going to use masonry paint...

    I'd also like to paint the underside of the roof, which will be OSB, (suitably covered on the outside!)

    Any reason I shouldn't use the masonry paint on the OSB? Should it be primed and or undercoated first? (I have some Leyland acrylic primer)

    Thanks in advance,

    Cando

    Masonry paint will probably go on ok but I'd uc first.

    Further info. I used OSB as fascia board in emergency. oil based undercoat and gloss black ,
    gets the sun, lasted 4 years before starting to flake.
