The present invention provides a water redispersible polymer powder (RDP) for use in the preparation of non-cementitious exterior finishing compositions such as textured paint formulations. Also provided are non-cementitious exterior finishing compositions comprising such RDPs and a method of coating a surface with such a finishing composition. When the RDP of the invention is incorporated into an exterior finishing composition such as a topcoat formulation of an external insulation finishing system (EIFS), the resultant composition provides improved dirt pickup resistance without a loss in wet abrasion resistance over conventional textured paint formulations comprising acrylic latex powders and, preferably, acrylic latexes.
