Category: Chimney - Topic: Sandblast Clean Chimney
Before refacing a painted or cracking cinder block chimney, it is a good idea to sandblast the chimney in preparation for applying the new surface. Any paint left on the chimney would stop the scratch coat from adhering to the underlying chimney blocks and the new surface might fail. Sandblasting or pressure washing should remove most of the paint and create a good working surface.
