I'm not sure what is happening with ceiling contractors but we simply could not get anybody to replace old one.
Finally last Saturday somebody popped in, old ceiling was taken down and new batons are added to strengthen whole structure (there was 1.2, gap in some instances).
9mm ceiling was installed and cretestone applied, all looked nice while wet but now that it is dry it is not smooth in some places and there some scratches.
It was only install so I'm painting it and sorting it out.
So I have few questions.
@Mannydefreitas if you have moment I would appreciate your advice
1) Can I sand it and what is the best way to do it, what grit paper (gave few senders)
2) Before I install polystyrene cornices should I apply primer to cretestone?
3) What is the best primer sealant to use before painting?
Thanks!
