Sofadher is a product of adhesion and a porosity regulator that is used on inappropriate media before the application of whitewash. It is the perfect primer before a Badisof's application (for the Badisof Plus, we will rather turn to the Sofix).
Sofadher is a film paint and does not apply on a support that has had covers.
Consumption : 1kg = about 30 m² (depending on support). Technical data to download below in the section "download".
