I have a nice internal wall which is pointed granite but unfortunately there is effloresecense as the wall is built into the ground. Is there anything I can do to stop the salt coming through the wall?
I found a product called Efflock http://www.getefflock.com/ but when I called a UK supplier they werent confident it would work as the damp is coming via the ground.
