' PRocnss or FORMING'AN A Rrrsrrc PAINT FINISH.
Application led January 27, 1926. Serial No.. 84,246.
My invention relates tof a paint composition andfalso to thev process of applying the composition to the surface to be treated lina vmanner to provide an artistic finish; it
- finish having numerous cracks or fissures forming various designs of an artistic nature Fig. 1 is a plan View of the crackle finish F ig. 2 is a sectional view of same. There is illustrated only oneV lparticular design disclosing a finish having numerous cracks or fissures, the process being susceptible of forming many and various designs of this crackle finish.
To 4that end the' invention consists in providing a lcomposition which is applied in two coats having different drying characteristics in that the undercoat dries slower than tle outer coat` thereby causing the outer coat to slip or move on the under coat so as to produce checks or cracks which result in peculiar designs of an artistic nature.
For-the under coat I preferably use what is known as gloss oil which consists of ordinary painters varnish mixed with rosin ir about the proportions ofl 50% benzine, 9% linseed oil, 1%.oyster shell, and 40% rosin. which is ineffect an elastic base. .For the outer coat, I preferably employ the following ingredients mixed substan- -tially 'to the proportions stated for a given quantity of material:
1/2 pt. wood alcohol. Y
- 1A; pt. denatured alcohol formula No. 5.
' l@ oz. highly refined benzine.
lbs. lead carbonate' or ordinary white lead.
The under coat is of a character that will dr slower than the outer coat, as the alcoho and benzine will evaporate rapidly from the lead carbonate, and this difference in drying characteristics causes the lead 'ca rbonate to slip or move on the under coat of varnish and rosin, which movement of the outer coat causes it to check or crack in a manner to form arbitrary designs of various kinds.
The composition may be applied to anyl surface upon which the desired effect is to be secured such as interior walls and any desired coloring matter may be added .to the ingredients'of the outer coat. The artistic effect maybe produced with large cracks or very small cracks or fissures, this depending.
upon the way in which the outer coating is applied, either lightly or heavily, and the design may be changed by changing the method of application, i. e. by applyingy the outer coat by vertical strokes of the brush instead of applying it by horizontal strokes of the brush. ATo that end, what has been called the outer coat mayI be applied by one or more applications, and if desired, what 'has been called the under coat may bealso made in one or more applications-of the varnish and rosin, and it is only necessary to let the under coat stand a short time before applying the outer coat.
It is to be understood that with changes in atmospheric conditions there will be correspondingchanges in the method of application and the exact proportins of the ingredients, but I have endeavored to illustrate V,
the composition of the materials and the method of application suitable forapplication under normal atmosphericv conditions.
Any one versed in the art will quickly learn by experience how to obtain the best results under any and al] atmospheric conditions.
Nothing set forth and claimed in the divisional application Serial -No. 117,242 filed June 21, 1926, is hereby waived.
Having thus described my invention, I claim as follows :v
1.,The method of applying a-finish to a surface, consisting in first applying tor said surface two distinct liquid coatings having different drying characteristics; thel under eating being slower to dry than the` outer coating. I
2. The method of producing an artistic finish to a surface consisting in applying to said surface a liquid composition, .thenl applying to said composition another liquidv composition having the characteristic of drying faster thanthe first composition.
In testimony whereof, I have hereunto set my hand this 24th day of December 1925;
CHARLES H. EGELHOFF.
