Ceiling paint

Hello. What paint is best for ceiling.
Our painter is using a roller on pole and it doesn’t look 100%, so maybe it’s the paint. Large tub of white pvc I think it’s called. Thanks

He maybe watering it down to much ..i never water it down and always use a brush ...roller make to much mess for me ...and depends if you have flat walls and ceilings ...

The paint shop bloke told me to water it down and it went horrible after a few months. All yellow and almost brown.
Did it without watering down the next time and it's lasted years. The stuff from Cadena 88 (by Consum) and has retained the colour. I think it's plastic based instead of water based.
I've also used it on my garden walls and it's lasted a long time.

Thanks for replying. As far as I can see he hasn’t watered it down, the problem is that our ceiling is extremely high and I suppose it’s lack of pressure on the roller/pole. All the other rooms are fine as standard ladder is high enough. I hate the thought of telling him again that it needs doing. A member on the forum has informed us he had a tower and I informed our decorator and he said don’t need it. We think our lounge ceiling is about 15+ feet high - not sure.
