Problem with Polycell Crack-Free Ceiling Paint

[Mr Pointy]

I'm painting some ceilings & have used Polycell flexible paint in the past, but an having problems with what is supposed to be matt actually drying to a satin finish. Two cans show the same effect so it's not just one rogue can. Has anyone come across this problem & can anyone recommend a good alternative?

Try a coat of matt emulsion as your final coat.

I bought some Wickes flexible ceiling paint & it's much more matt than the Polycell. Cheaper too.
