The method of the present invention provides a coated cementitious substrate with a glossy appearance, dirt pick-up resistance, and efflorescence resistance. The method includes the steps of applying a coating formulation onto a green cementitious substrate and of curing the coated green cementitious substrate. The coating formulation contains an emulsion polymer with a molecular weight in the range of 30,000 to 300,000 and a glass transition temperature in the range of −10° C. to 60° C. Also provided are an emulsion polymer including a photoinitiator monomer as polymerized unit, a coating formulation including photoinitiator molecule, and a coating formulation including an ethylenically unsaturated polymer. |
