Dyebrick Soot Wash is designed to replicate heavy, black, carbon-based pollutants prevalent in London and many Northern industrial towns and cities. The main ingredients include a blend of high-grade carbon black pigment and a micronized, colourfast high intensity black iron oxide pigment, an effective water-based ‘Carrier Solution' and a unique 'Fixing Agent’ that, when blended, will produce a durable and natural finish that allows your masonry to breathe.
