Special concept - a restoration mortar that can be “feathered out to zero” – High quality binder – Low free alkali content – Very good adhesion to sides – Practically free of inherent stress. The pigments used to achieve the desired colour are resistant to lime and cement and lightfast. Strength, granulation and colour are selected to match the substrate. Special grain compositions (coarse aggregates) to improve optical properties can be formulated at the plant upon request.
