BRICK ISSUE GUIDANCE :
PEACOCKING IN BRICKWORK
SYMPTONS, PREVENTION, CURE.
Blue bricks can sometimes have what appears to be an oil type of stain across the face of the brick or around the perimeter of the brick face (sometimes referred to as ‘picture framing’).
Some blue bricks may have a very thin layer of colloidal silica, through which light diffraction can occur, or this can happen through another form of cementitious material, often stemming from the mortar. Most Peacocking appears because the brick or brickwork has been saturated during construction. |
Peacocking is purely aesthetic and has no detrimental affect on the technical ability and performance of the brick.
Peacocking can sometimes appear to change when viewed from different angles, which in turn makes cleaning brickwork with peacocking very hard. |
