Buildings change. Dirt and air pollutants collect on the façades over time. Moisture penetrates the façade. If renovation work is scheduled, the façades are usually cleaned, but sometimes this is not enough.
If there are extremely high levels of salts, we recommend reducing the salt levels in the areas close to the surface, as an alternative to permanent single or dual-layer restoration render systems, working with sacrificial renders, also called compress renders.
The use of traditional material and processing methods is one of the basic requirements when restoring listed buildings.
