Metal cornerbead for drywall partitions is coated with a water reducible acrylic resin to improve the adhesion of joint compound to it. Aqueous solution of resin may be added to roll-forming lubricant such as hexylene glycol.

Method for improving adhesion of joint compound to metal cornerbead

Substrates such as metal, plastic, hardboard and plywood may be coated with a translucent film of a filled acrylic resin so that a decorative stain may be applied. The filler in the acrylic resin is an extender pigment having a mean particle size of from about 5 to about 7 microns.

Translucent stainable coating

A composition and method for treating the surface of a metal structure adapted to be used for such purposes as a cornerbead and to have a cementitious material such as a joint compound applied to the surface thereto, the compound and composition and method resulting in the improvement of the adhesion between the surface of the metal structure and the cementitious compound applied thereto, which comprises preparing a composition such as that comprising a forming lubricant for processing the metal structure and a minor proportion of a polyfunctional aziridine incorporated therein. The presence of the aziridine enhances the adhesion properties between the surface of the metal and the cementitious compound even when less highly processed metals and less expensive compounds are utilized.

A metal article is made to look like wood by impressing a three-dimensional wood grain pattern in its surface, coating the pattern with a translucent film, and staining the film. The stainable film is an acrylic resin filled with an extender pigment whose mean particle size is from about 5 to about 7 microns.

Metal article having three-dimensional wood grain and stainable coating

A water-based stain having a working time of from about 1 to about 3 minutes and a tack-free drying time of from about 10 to about 15 minutes at 160.degree. F. comprises an acrylic latex, a drying oil, ester gum, a glycol, a hydrocarbonaceous solvent, and pigment.
