There is provided a new sag resistance imparting agent selected from among gelatinous metal hydroxides and metal salts capable of forming a gelatinous or hydrated hydroxide in the presence of a water soluble alkaline material, the agent being useful for providing sag resistance in various adhesive compositions including (a) hydraulic non-dry-set compositions comprising an hydraulic cement or plaster of paris, and (b) non-hydraulic compositions comprising a room temperature hardening polymer in the form of a resinous liquid or an emulsion, suspension, dispersion, partial solution or total solution. Methods of imparting sag resistance to adhesive compositions such as the aforementioned and methods of use for the sag resistant compositions in the installation of wall and floor covering surfaces are also provided. |
