  • Method of producing opaque adherent coating on the surface of substantially hydrated cementitious substrate
    Patent number: 6045871
    Abstract: A method of producing an opaque adherent coating on the surface of a substantially hydrated cementitious substrate is provided. A waterborne storage stable sealer comprising an aqueous medium containing a binder polymer and an opacifying polymer is applied on the surface of such a cementitious substrate. Upon drying the layer substantially hides the primary efflorescence typically present on the surface of the cementitious substrate. Applicants have unexpectedly discovered that by optimally adjusting the thickness of the coating a weight amount of waterborne storage stable sealer solids in the waterborne storage stable sealer and a pigment volume content of the opacifying polymer in the storage stable sealer the opaque adherent coating is produced on the surface of the substantially hydrated cementitious substrate.
