"Polycarbonate is very shiny and smooth.
Paint is not a great way to block the light.
You would be better using hollow soffit on the inside and then seal it with silicone.

Hope this helps"

"It is always best to get a windows doors / conservatory expert to look at what you are trying to achieve first as painting the polycarbonate roof could cause problems either initially or in the long run.
It is always best to change the glass panels as there are lots of different sun blocking materials on the market."

"I wouldn't recommend painting them to be honest it won't last paint on them and it will still be hot it won't stop it being hot in there...the best thing to do is have roof tiled and insulated maybe flat roof or peak.then in winter it will be warm in summer will be cool..painting them paint will only flak of and room will still be hot as sun hits plastic sheets...tile roof best option hope this helps"

"Hi Ayres roofing here I wouldn’t really recommend painting with a brush if you don’t want light threw I would recommend either of the following fit Epdm Firestone rubber or fit a cosy roof system which is basically tin tiles boards reflect etc. Or if you just want something cheap and cheerful to fit rubber on top of the poly roof if it’s only to block the light but painting it you will never win hope this helps"

"Polycarbonate roof is too smooth to paint would take 4/5 coats so it blocks it out, maybe try sanding the plastic Down with sand paper so it goes rough then paint it so it gives it a stick, or either speak with a tinter who can tint it"
