The present disclosure provides for a coating formulation that includes a pigment, an organic aqueous emulsion and an organophosphonic acid of the formula: where R is a saturated or unsaturated alkyl having 2 to 10 carbon atoms or a substituted or unsubstituted aryl having 5 to 10 carbon atoms. The coating formulation can be used in forming a topcoat in an exterior insulation and finish system (EIFS). The present disclosure also provides for a method of forming a topcoat on a surface of the EIFS that helps to protect the underlayment of the EIFS against both weathering and moisture while helping to maintain color retention.
