PLASTERING COMPOUND.
SPECIFICATION forming part of Letters Patent No. 291,408, dated January 1, 1884.
Application filed April ll, 1883. (No specimens.) I
To all whom it may concern:
Be it known that I, HANNAH E. SCALES, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have inventedcertain new and useful Improvements in Plastering Oompounds; and I do hereby declare that the same are fully described in the following specification.
. face, like ordinary tinted walls.
The object of this invention is to furnish an improved plastering compound designed for a finishing-coat in rooms, and for ornaments, moldings, statuary, and the like. This compound is colored uniformly throughout, and hence requires no subsequent labor, time, and material in tinting the surface; nor is it discolored and defaced by scratches on the sur- It may also be made Water-proof, so as to be uninjured by repeated washing or by steam.
My improved composition has for its ingreclients the following substances in about the proportions named below: I take, by measure, one part of air-slaked lime, one-half part of fine sand, one-half to two-thirds part of rice-flour, and one-fourth part of fine salt if beach-sand is used; otherwise one-half part. These I mix dry, with the desired coloring-matter, preferably dry aniline colors, being careful to make the mass homogeneous by thoroughly mixing its elements to insure uniformity of color and avoid streaks. When about to be applied to the wall or other surface, I render the mass plastic by adding sufficient weak glue in which has been dissolved, while boiling, from ten to twelve grains of bichromate of potash to each quart of the liquid, for the purpose of render ing the finished surface water-proof. When the liquid is added, the whole is stirred, so as to effectuallymoisten all the ingredients and intimately incorporate them into one mass of uniform consistency and color. spread over the foundation-coat with the trowel in the same manner as any fine plaster.
Walls finished with my compound may be frescoed either in oil or water-colors as readily as ordinary walls.
For stucco or other fine work I sometimes substitute plaster-of-paris for the lime, and reduce somewhat the proportion of sand and salt, While retaining the full percentage of rice-flour. Less coloring-1natter is needed than when lime is employed. The elements are mixed and stirred with the weak glue, as already described, adding the bichromate of potash, as stated, when it is desired, in either case, to make the surface water-proof.
I claim as my invention-- The compound herein described for plaster or stucco work, consisting of rice-flour, sand, salt, and lime or plasterof-paris mixed with weak glue, and compounded together in the proportions substantially as stated.
In testimony whereof I hereto affix my signature in presence of two witnesses.
HANNAH E. SCALES.
