The present disclosure provides for an aqueous coating composition to coat and form a film on porous construction materials to help in controlling efflorescence in the porous construction materials. The aqueous coating composition includes a binder having an acrylic polymer in an acrylic polymer waterborne dispersion, wherein the acrylic polymer has a glass transition temperature (Tg) of 1° C. to 60° C.; and an alkoxy silane coalescing agent in a waterborne silane coalescing emulsion. The aqueous coating composition optionally further includes an additive selected from the group consisting of a pigment, a filler and combinations thereof. In one embodiment, the alkoxy silane coalescing agent provides the only coalescing agent for the acrylic polymer waterborne dispersion in the aqueous coating composition.
