interior walls showing outline of cavity blocks
Posted: Wed Apr 08, 2009 2:15 pm
Can anyone advise me about the sudden appearance of the outline of cavity blocks on my interior lounge walls. The outlines look like shadows on the walls and are dusty grey.
I want to redecorate and do not know what to do to ensure this problem does not happen again.
Advise would be very much appreciated.
