Verfahren zur Verhuetung von Farbauftragungen auf Flaechen aus Natur- und Kunststein

摘要

Surfaces of natural and artificial stone are damaged by undesirable colour applications, since pigments penetrate into the pores and capillaries of the base material, colouring it in such a way that it becomes difficult or even impossible to remove the colour. Such damage is avoided by impregnating the surfaces to be protected, forming a separating layer upon which a disposable, colour-absorbing layer is applied, which cannot penetrate through the impregnating layer and which is easy to remove, together with any colour, by an appropriate process, thus preventing any loss of the base material.
