Storage stable pigmented coating composition

A method of coating a cementitious and/or masonry substrate, the method comprising applying a one-part aqueous coating composition to the cementitious and/or masonry substrate,

• wherein the aqueous coating composition comprises:
• at least one pigment,
• at least one emulsified polymeric binder,
• the emulsified polymeric binder comprising at least one of:
• a) (meth)acrylamide or derivatives thereof as a polymerized monomer;
• or
• b) 1 weight % or more of at least one surfactant based on the total dry weight of the total monomer in the emulsified polymeric binder;
• at least one water-soluble silicate,
• optionally at least one filler, and
• optionally at least one additive;
• wherein the one-part aqueous coating composition has:
• a weight ratio of emulsified polymeric binder to the water-soluble silicate from 65:35 to 95:5 on a dry weight basis;
• and
• a pigment volume concentration (PVC) from 5% to 85%;
• wherein the PVC is defined as:
