Hi

Similar questions have been asked in the past, but can anyone help please?

I have had a skim coat of plaster put over some old tile adhesive, and over artex on the ceiling in my bathroom.

How long to I have to leave it before painting with emulsion?

Also, is it best to put a watered down coat of emulsion on new plaster first?

Thanks for your help

Hi tricky,
Depends on the conditions, heat and humidity.

The plaster will change colour, lighten, as it dries but that is just surface.

I had 3 walls and a ceiling done took 4 days in December to dry.

Unfortunately there is no rule as such but generally after 2 to 3 days for a small room should be good but it's just a guide.

Water down adding about 30% water for first 'mist' coat of emulsion.

Hi guys

Just wanted to add to this thread as I have spoken to a few plasterers in the last few days getting quotes and some of them have advised that I should coat the new ceiling with PVA before painting.

They have told me that this will prevent cracking and provide a better surface to paint onto once its all dry...

Is this right, and of so, what strength of PVA and type should somebody use on newly plastered ceilings once they are dry?

Is it just regular PVA wood glue watered down? To what strength?
Sorry for so many questions

Thanks
Richie

Applying PVA to a newly plastered ceiling is a bad idea.

Use a mist coat of diluted emulsion paint, preferably Dulux supermatt.

Never use cheap paint as it is false economy.

I started that thread as i alway told my customers to do a mist coat 4-1ish water-paint, but it appeared i'd given my customers dodgy advice for 4 years or so! no complaints though
I would always do a mist coat rather than use pva on fresh plaster, but then i only put it on not paint it
