Hi All,

I am having my walls professionaly done by solid plasterer. Any thoughts how long I should wait before painting? The plasterer said a few days, but then again he told me that any old acrylic sealer/undercoat would be OK (I understand acrylic isnt suited to sealing/binding solid plaster - must use oil based products) so I am wanting a second opinion.

Thoughts

I waited 2 months before doing anything to my new plastered bathroom. A couple of surface hairline cracks appeared in the finish plaster as the walls dried right out in the heat of summer. I touched up those hairlines and then used Dulux Sealer Binder prior to painting and the wall are now perfect.

Cheers

On my last reno i waited 6 week before i painted the walls after the white set had been applied .

the idea is to get as much residual moisture out of the wall as possible before it is sealed if you can leave some windows or doors open this will help . .

P.s i hate using oil based paints but it is worth it in the long run ..

12 weeks like i had posted in the last mention of solid plaster

Thanks all for your responses. Looks like I'll have to sit it out for a while before painting.

Just had a thought re sealer/binder. Would anyone recommend sealing with bondcrete instead of oil based solid plaster sealer/binder? I could then apply regular acrylic undercoat. Will this allow walls to breath better than oil based product?

bondcrete is only low grade pva so don't bother

3 days is fine 2 months is a joke once plaster is pink you can paint it

I cant understand a solid plasterer saying you can paint after a few days.
A good rule and true is three months in summer 6 months in winter. That is what I learned in school as an apprentice plasterer and a good measure. Some buildings retain moisture a lot more than others. Lately I have been using ajacks plaster and on the bag it mentions use oil based sealer. So if the plasterer had left over bags read the information.

Building standards specify three months before painting. Like Jags said leave plenty ventilation windows open and fans onto the walls. The longer you wait the better.

It would be quite foolish to paint 3 days after plastering. 2 Months is not a joke and probably on the borderline to being too soon.

Hi
Three days IS NOT fine!

The longer the better. 8-12 weeks should be ok!

Hi
Good quality acrylic sealers are ok on plaster walls. You can use an oil based sealer but you don't *need* oil based sealers, though an oil based sealer would be better in wet/damp areas.
