Hi sifus, I wish to get some advise from you all. I just recently VP and started submitting the defects. The interior wall finishing overall is ok except some drips here and there, at least for a newbie like me.

As I'm planning to add new power point and shifting existing one, it's unavoidable that I will repaint my new wall but this is not a problem as I do plan to paint new colors (both light and dark colors at different walls over the existing light grey color). I do have few questions here and hope you can clear my doubts, this would help me to set the expectations when I looking for painter to discuss about their scope.

1. Do I need to scrape off the existing paints?
2. Should I apply 1 coat of primer first?
3. I will be doing the plaster ceiling as well, should I paint the wall first or settle the plaster ceiling first?
4. I heard that you should let your paint work settle down by not opening the windows for few days to avoid hairline Crack. How long should I wait for this before I proceed to my next step of renovation?

Thanks in advance.

Thanks bro for the swift response, truly appreciated!

Opps, thanks Sis! I found you in almost every single thread I'm reading recently about the renovation and your advise in those threads really helped me a lot. I respect and admire your knowledge and expertise, SALUTE.

Ty for the additional tips. If I read it correctly, I do not need to apply the primer over the entire wall but only the parts over those hacking runs?
