In my plastered basement I have Efflorescence salts (white cotton fluff) coming through the wall in certain places. I understand how this is formed and that it requires salt and a water source. The Water source has been identified, but will take some time for me to resolve but I will do this at some point... What I want to know is how can I stop the Efflorescence salts coming though the paint/plaster work in the interim until I resolve the water source issue? Is there some type of paint/solution which will prevent the salts appearing on the wall? I have tried Thompsons Damp Seal paint, but the salts lift this off the plaster in bubbles, and once they crack the salts start appearing again.
