Smelly plaster in cellar

imported_Duncan

We have a cellar that was converted by the previous owners over 5 years ago. They did an ok job but over the last year damp has caused some of the plaster to come away around the bottom of the walls.

I recently removed the loose finishing plaster, let the wall dry out with the aide of 2 de-humidifiers and skimmed the base of the wall again with some B&Q readmix finishing plaster. Before applying the plaster I PVA'd the wall.

All was well until 3 days after finishing the plastering (it is not yet painted) it has started to smell quite strongly and it is not pleasant and the missus is not happy

Has anyone else experienced this? Will the smell go after some time or is there a deeper problem that needs to be sorted??

Any views gratefully received.

Cheers,
Duncan

I sounds to me like the plasters moisture is not properly drying out. I would think the original cellar walls were not water sealed at all. So even know you made an attempt to seal the surface. The moisture can still come in threw all the surrounding areas not redone. The cause of the pealing plaster most likely was from this. I would think this will remain a problem until the complete surface is sealed. (requiring complete stripping of the surface). Or sealing from the outside of the wall. Normally only done by professional services. Make sure you check out if the warranty there work if you were to consider this method.
