    摘要： 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.

    摘要： The present invention relates to a calcium sulphate-based product (e.g. a wallboard) comprising gypsum and a shrinkage resistance additive. The shrinkage resistance additive is a metal nitrate, hydroxide, acetate or sulphate and is preferably provided in an amount greater than 4 wt% (based on the amount of additive and gypsum). The additive may be a nitrate of an alkali metal (e.g. potassium), an alkaline earth metal (e.g. magnesium or calcium), a transition metal (e.g. iron or zinc) or aluminium.
