I have an interior party wall which has rising damp so I hacked off the old crumbly plaster and had a chemical DPC installed which will hopefully stop the damp.
The wall is mainly made up of granite but has also been cobbled with some brick, basically very ugly looking. What is the best way to re-render the wall? Cement and sand mix with water proof additive? Then skim on top?
Any ideas would be greatly appreciated.
