The present invention relates to a waterborne cementitious coating composition comprises: a) an aqueous polymer latex comprising: a first monomer selected from the group consisting of a vinylarene monomer and a (meth)acrylate monomer; a second monomer which is a meth(acrylate) monomer; and one or more epoxy silane; and b) an inorganic component comprising: cement; and one or more solid filler. The invention also relates to methods of forming the water-resistant, flexible cementitious coating, layer or membrane, kits for performing the methods, and coatings formed using these methods.

An agglomerated mineral composite coating composition may include a coating vehicle, an agglomerated mineral composite including a first inorganic particulate mineral, a second inorganic particulate mineral, and a binder. The binder may facilitate agglomeration of the first inorganic particulate mineral and the second inorganic particulate mineral. A method of making a coating composition including agglomerated mineral composites may include adding a first inorganic particulate material to a second inorganic particulate material to form a mixture, adding a binder to the mixture to form agglomerated mineral composites, and adding the agglomerated mineral composites to a coating vehicle. The first and second inorganic particulate materials may include diatomaceous earth, mica, perlite, aluminosilicate, talc, and an alkali earth metal carbonate. The aluminosilicate may include kaolin. The alkali earth metal carbonate may include calcium carbonate. The binder may include sodium silicate. The coating composition may include not more than 10% by weight titanium dioxide.
