Abstract

This method serves to provide porous substrates with a thin layer sealing them completely without penetrating into the porous substrates. A self-hardening, liquid epoxy resin is first spread over a plastic foil which is previously coated with an anti-sticking agent. By a second foil placed over the resin layer, the latter is uniformly spread using thin strips for determining its thickness. As soon as the viscosity is increased a little, the second foil is pulled off. Now, the viscosity of the resin layer is increased so that no resin can penetrate into the pores of the substrate when the foil with the resin layer is pressed on. After the resin layer hardens on the substrate, the foil covering it is pulled off.
