Preparing Celling for Painting

[chrisb1357]

Hi all,

Can anyone advise me on how to prepair my celling for painting a white coat of paint on.

The celling sometime ago had tiles on which was removed by the local council. I have now also removed all the old glue and some paint which was left from these and have filled some holes and crack in and then sanded over the whole celling area.

My main question is now i have done the above what is the best way to paint the celling white. I am told not to use PVA so what can i use for a first coat to seal the celling so the other coats apply ok.

If ceiling now all sound, you can just use a thinned down coat of the emulsion you are using, or if preferred some kind of contract emulsion. If ceiling dusty or porous, you can try an alkali resisting primer first.

Hi,

Well it was sanded and i plan to clean the dust off next week. Not planning to paint until a few weeks time so i guest it will be clean by then

If i was to use a alkali resisting primer first would this mean i dont need to apply so many coats of white paint. What does alkali resisting primer mean and what does it do as i have never heard of it before you see.

Notice my sanded celling is still a bit dusty and the odd bit of filler has come away yet again so going to have to refill and i am now not sure if to prime first then paint or just paint stright on it

Another thing is i cannot seem to find this sort of primer on B&Q or Wickes website

Alkali resisting primer is for concrete. Just thin your first coat by 25%. Then the following coats by 10%. Full thickness paint leaves nasty roller stipple.

Sorry to be a pain but when u say 25% thin on first coat does that mean 75% paint and 25% water. How is it best to calculate this when using a tray for the paint.

Is the above required on B&Q paint as that seems allready thin to me
