Drying out plaster
Anonymous user 15/03/2024 - 2.40 PM
I have recently built on a small extension to my home using an original garden wall and 3 new walls. Plaster has fully dried on new walls but still wet on original wall after about 10 weeks. How can I get this wall to dry as it is holding up completion of work. Have tried dehumidifier it helped but still not dry

It could be a couple of things - hard to say without knowing much about the building.
Is the original wall a single brick wall? Is the original building a Victorian build? If so, it could be that the original wall was porous and built with lime mortars which allow moisture to move in an out of the building.
If there are any blocked air vents or a chimney that has been entirely blocked up without an air vent being installed, this too could contribute to the moisture problem.

Air circulation. Fans etc blowing and extracting to exterior. For example plaster always dries last in corners where there is little or no air circulation

Hi ,
Did the original garden wall have a damp course in it ?
If not then any damp can continue rising in the wall and keep the wall damp and stopping your wall from drying out thoroughly.
The solution is to take off the plaster back to brick or block drill and inject a damp proof membrane and replaster with limelight renovating plaster and finish plaster .
But without seeing myself whats causing it im taking a guess that is the cause and solution .
