Abstract: A formulation for forming an ink-receptive coating on a substrate includes more than 1 percent by weight (wt. %) of dry matter of a mesoporous material including particles of precipitated silica, wherein the mesoporous material is incorporated in the formulation in the form of a paste having a water content within a range of 60-95 wt. %, wherein the paste has been obtained by washing and dewatering of a slurry formed by mixing alkali silicate with a salt solution so that coagulation occurs.

Abstract: The invention relates to a plasterboard comprising a layer of plaster and at least one facing arranged on the latter, the facing being coated with a coating slip comprising a microporous material, said microporous material comprising agglomerates of precipitated silica. The invention also relates to a coating slip, a facing, and methods of manufacture for supplying said plasterboard.

Abstract: Coating and jointing material systems for wall construction are provided. The coating is applied to drywall elements prior to installation and is compatible with the jointing materials such that a substantially homogeneous surface may be obtained after the drywall elements are assembled with jointing material and the jointing material is dried. Methods for the construction of interior walls and interior construction systems are provided.

Abstract: A coating for wall construction is provided whereby a level 5 finish may be obtained without the need for a finishing coat or final skim coat. The coating may be applied to drywall elements prior to installation and is compatible with jointing materials such that a substantially homogeneous surface may be obtained after the drywall elements are assembled with jointing material and the jointing material is dried. The coating formulation includes a noncellulosic thickener, a binder, a mineral filler and water. A method for the construction of interior walls and a construction assembly for interior walls is further provided.
