Frequently Asked Questions
This is called efflorescence and is caused by water reacting with the natural salts that are contained within the brick. It is quite common for walls to be cleaned prior to tinting and aggressive cleaning, such as the use of a pressure washer, can pull the slats to the surface where they then evaporate as they dry. Efflorescence can also occur with new build properties when the brickwork was not protected from the elements during construction.
The efflorescence can be removed using a salt inhibitor that you spray on. Please note some touch up of the tint may be required if an aggressive product is used.
