A fast-setting magnesium phosphate one-component adhesive/grout is used to bond tiles, e.g. ceramic tiles, to a substrate, e.g. sheet-rock. The grout comprises an activator prepared by e.g., mixing diatomaceous earth with at least a sufficient amount of an ammonium phosphate solution to form a paste

A fast-setting magnesium phosphate one-component adhesive/grout is used to bond tiles, e.g. ceramic tiles, to a substrate, e.g. sheet-rock. The grout comprises an activator prepared by e.g., mixing diatomaceous earth with at least a sufficient amount of an ammonium phosphate solution to form a paste then heating the paste to coat the pores of the diatomaceous earth and result in a dry solid which is then milled to yield the activator, magnesium oxide, diammonium phosphate, boric acid, and sufficient water to form a paste. This grout is applied to the surfaces to be bonded which are then brought together to form a composite which is allowed to set at ambient temperatures forming a durable bond in about three hours.

A process for bonding tiles to a substrate which comprises: (a) preparing a cementitious magnesium phosphate composition comprising: (i) an activator prepared by mixing an inert porous material with a sufficient amount of a liquid P2O5-material to at least form a paste followed by heating the result

A process for bonding tiles to a substrate which comprises: (a) preparing a cementitious magnesium phosphate composition comprising: (i) an activator prepared by mixing an inert porous material with a sufficient amount of a liquid P2O5-material to at least form a paste followed by heating the resulting material to yield a dry solid; (ii) a source of magnesium; (iii) sufficient water to form a paste; (b) applying the magnesium phosphate composition to either the tile or substrate, or both; and then (c) bringing together the tile and substrate with the cementitious composition therebetween to bond the tile to the substrate and allowing the cementitious composition to set at ambient temperatures.
