Spalling is a term used to describe the condition of a clay brick front that has suffered due to the weather and the front face has either fully or partially dropped off or worn away.

Bricks are mainly made of clay and are heat fired in a kiln to give the outer facing side a harder finish to resist the impact of wind, rain and air pollutants. Unfortunately sometimes the moisture in a brick can become frozen in winter and the expansion this causes quite literally blows the front protective layer off the brick over a number of years. This then exposes the softer inner core of the brick which is highly porous and absorbs a lot of water – in excess of a pint of water – in heavy wind -driven rain. This can lead to penetrating damp and of course even greater degrees of spalling will occur.

A common error to try and protect spalling brickwork or stonework is to paint over the damaged area but unfortunately this will lead to greater moisture retention across the whole wall and increase the chances of further spalling in other brick faces !!
