Can anyone please advise on the use of salt neutralising solutions for use on good plastered walls, after having a chemical damp proof course injected.
Our son is buying a terraced property which has newly plastered walls which read above acceptable levels with a test meter. We could do the damp injection again but it would be a shame to have to hack off the plaster as there aren't any badly blown sections and obviously the cost would be considerably less.
Having said that I would not want him to have to replace the plastering in the future because the neutralising solutions were not working.
