Efflorescence has become a more frequent occurrence on new brick façades in recent years. This is the result of an excessively high level of moisture absorption in the masonry during the construction phrase during which the brickwork cannot always dry quickly after the mortar has been applied and therefore the lime content in the mortar cannot set.
The joints on a building have a technical function and can make up to 20 % of the overall façade. However, the shape and colour of the joints can also have a decisive impact on the appearance of the façade.
Thanks to hydrophobizing impregnation, the capillary water absorption of a façade through rain and splashwater is significantly reduced. The water repelling, hydrophobic treatment is therefore a sensible damage-preventing and/or supplementary measure.
