Painting plaster walls - timescales - plaster sealer

[climber05]

Hi,

I've seen lots of threads on this subject but maybe this one is slightly different. I am an amatuer DIYer/decorator so not all the right terminology might be correct.

In mid August, I had some plasterwork done to a damp wall. A week ago, I painted it with plaster sealer. Have I left it long enough to apply this? Some advice is that 6 weeks is enough but i have also been advised to leave the plaster to dry for 6 months.

If I should leave the plaster to dry for 6 months, is it ok with the plaster sealer on it? If not, do i have to remove it? If i can leave it on, do I have to extend the drying period beyond the 6 months?

Thank you for all your advice in advance.

If its just a skim the you'll be fine. If a bonding coat has been applied first its then that it takes a lot longer to dry out but you've left enough time if this is the case.
Can't see that you'll have any problems

Agreed.

If you have had a full base coat and skim, four months is usually ample time for it to dry unless it is excessively thick or the underlying walls had been damp and required longer to dry following any treatment. You may still find that a few months down the line you will get hairline cracks appearing in the plaster but this is common and not because you haven't left enough time for it to dry.
