I am attempting to carry out a loft conversion in a terraced house, one
problem is that in the attic the wall ajoining the other property is an old
stone and mortar construction with a brick chimney in the middle, the
chimney bricks are covered with cement.
Rather than cover the wall with plasterboard I would like to keep it as a
feature however the house is 1920`s and the stone and mortar in places is
rather crumbly when touched.
I need to seal it, I thought about a PVA Water mix, but that`s just me
thinking out loud.
