Getting moisture out of gypsum plaster
Anonymous user 16/03/2024 - 2.41 PM
When I moved into my Victorian flat, there were some signs of damp on an external wall. I had the gutter replaced and the wall skimmed with gypsum plaster (I've since learnt that I should have specified lime). The plaster never dried in some places so now I still have large damp patches. I recently had pebble dash removed from the outside to let the wall "breathe", but I'm keen to dry out the damp as quickly as possible so I can decorate. Will a dehumidifier help? Are there other ways to speed up the process?
Are you a tradesperson and able to answer this question?

Yes it would help. But to be brutally honest. Your house/walls are not going to be breathable if one side has gypsum when it should have had lime plaster etc
You’ve done the right thing removing the render externally but you may as well do the same I internally for full affect

A dehumidifier will help but may need a air vent putting in

When using the dehumidifier remember to chose the windows and doors or you will be dragging the moisture from outside and it will never dry.
If you're wall's are solid you should remove it and start again.
Take render off inside use dehumidifier till dry render with a lime based render then skim.
Should resolve the problem
