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."

Answered on 23rd Mar 2021 - Member since Mar 2021 - report"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"
