It was Wickes general purpose OSB2Wuffles":35nlw9kb said:Really? What sort of OSB is it, OSB3 is pretty much waterproof so I would have thought any paint would do. That's what I'm planning anyway, splash of water-based emulsion on it.
Cheers, I'm awaiting a response from Johnstones', they've recommended Flortred , but a primer will likely be necessary as it's for the roof and all [extra] ways to seal it will be considered - I'm [perhaps vainly] hoping to install & forget - i.e. if it can last as long as the polycarbonate should without issue, that's as much as I could expect...Never tried painting it, but I used the tongue and groove 600 mil by 2.4 's 18 mil thick for my floor in the workshop, I used Johnstons floor varnish – two coats and it’s still pretty damn good after 6/8 years.

I think bituminous coatings are possibly bad for polycarbonate - again I'm asking the publisher of the compatibility chart and await their reply as they only list...,Hi Xtian, The Johnstons floor varnish I used was water-based and I wouldn’t recommend it for a roof, what’s wrong with black horrible bitumen out of a tin? That would certainly seal it.
I know right - but there's no completely opaque polycarbonate product, the finish is to achieve something complimenting the darkest tint PC sheet [bronze], to see a uniformly dark roof rather than a tan colour board visible under a bronze tint sheet..., which you may say is just an aesthetic detail complicating things and nothing else, and to get over it they way it would look without trying to match for colours - but that's ultimately everyone who sees it, not just me...What purpose will the painting serve? If its properly clad why paint it?
