To all whom it may concern:

Be it known that We, CoNsTANoE M. GAuLooHER and JAMns N. STACY, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Processes of Finishing Wall-Surfaces, of which the following is a specification.

This invention aims to disclose a novel method of finishing wall surfaces, and aims further to provide a finish for a wall surface which will take the place of wall paper, calcimining, etc., and which will be inexpensive to use and more attractive in appearance.

Incidentally the invention aims to disclose a process for finishing wall surfaces and a combination of materials to "be employed in such process, which will render the wall surface sanitary, capable of being readily washed or otherwise cleaned, and which affords no crevices or hiding places for in- 1 sects, as is the case in the use of ordinary wall paper.

In carrying out our invention, we first prepare a sufiicient quantity of a solution of saltpeter in water, using two pounds of saltpeter to each gallon of water. With this solution, the wall or ceiling to be finished is thoroughly washed. We have found that this solution is highly efficient in .clearing the wall surfaces and that it serves also as a germicide. We next prepare a suitable quantity of a solution of alum in water, using two pounds of alum to each gallon of boiling water, and apply this solution to the wall, repeating the application until crystals form. The application of this lat; ter solution to the wall provides against sweating and the consequent discoloring of the wall finish. We next sand paper the wall until a very smooth surface is produced and all crevices and cracks in the wall are filled up. Wethen prepare a suitable quantity of a sizing consisting of three pounds of linseed oil mixed with each gallon of varnish and apply this sizing with a brush to the wall surface.

Prior to applying the sizing, we mix about two pounds of ground asbestos or mineral wool with about one pound of dis-, integrated silk, wool, wood fiber, cotton, mica, saw-dust, or like substances, either in Specification of Letters Patent.

their original colors or shades or colored mechanically by the use of any suitable coloring material.

Immediately after the application of the sizing to the wall surface, and while the surface is still damp, the mixture of asbestos or mineral wool, and one or the other, or a combination of the disintegrated materials mentioned above, is blown onto the surface by any suitable machine or instrument until the desired shade and appearance has been obtained. It will, of course, be understood that the mixture of asbestos and disintegrated fibrous material will be caused to adhere to the wall surface by the sizing and that when the sizing has become 'dry, the particles comprising the mixture will be securely anchored to the surface. It will further be understood that a Wall may be finished in the manner above described in a slngle color or shade, or different mixtures may be employed and applied in any manner to display ornamental figuresor designs.

We wish it to be understood that we are not limited in use, in the mixture which is to be blown onto the wall surface, to the particular substances above mentioned, but that various fibrous or scaly substances may be employed, and under some circumstances even finely powderedsubstances including pulverized mineral wool.

WVhat we claim is: a 1. The herein described process of finishlng wall surfaces consisting in first washing the surface with a solution of saltpeter and then applying to the surface a solution of alum and allowing the same to dry, and then applying to the surface a sizing, and finally, before the sizing has dried, dusting onto the surface a mass of finely divided particles of a finishing material.

2. The herein described process of finishing wall surfaces consisting in first washing the surface, then applying to the surface a solution of alum and allowing the same to dry, then sand-papering the surface to asmooth finish, next applying to the surface a sizing, and finally impinging upon the surface a finishing material before the sizing has dried.
