Abstract

The invention relates to a process for the stabilization of dusting surfaces characterized in that the dusty ground is tilled or scarified and mixed with polymers in form of water-redispersible polymer powders, which are optionally reemulsifiably modified, or reemulsifiable modified aqueous polymer dispersions, which are optionally sprayed on to the untreated dusty ground. In a preferred embodiment the redispersible polymer powder, respectively the reemulsifiable modified redispersible polymer powder or the reemulsifiable modified aqueous polymer dispersion, is combined with hydraulically setting compounds, preferably cement and/or gypsum.
