Zusammenfassung:The basic substances of the polymer are at least 10% vinylacetate, co- or graft-polymerised with ethene and/or vinylalcohol and/or acrylamide and/or acryl acids and/or acryl esters, as dispersion or soln. in water or other solvent medium. The polymer is equally distributed corresp. to a quantity of between approximately 40g and approximately 500g of polymer per m2 of room or building surface. After drying a radon-blocking and moisture-permeable layer is provided.
