This invention relates to paints and more
particularly to a paint which isv adapted to'be
polished ‘by the application of friction after the
paint‘ has taken ‘an initial set, and is a continu

' One object of the present invention is to pro.
duce a paint which may be polished by the ap
plication of friction thereto after the paint has
10 taken an initial set.
Another object of the invention is to produce
a paint suitable for use in connection with the
method described in the United States patent to

‘While lithopone and aluminum silicate have OI
been found to produce an excellent paint, they
may be replaced with other well known opaque
pigments. For example, the lithopone may be
replaced with white lead or titanium oxide and
the aluminum silicate can be replaced with talc 10
H2Mg3(SiO3)4, silicon di-oxide (S102), or calcium
carbonate (CaCOs).
The proportion of the two pigments‘ may be
varied to decrease the lithopone and increase the
aluminum silicate, higher percentages of the 15
aluminum silicate in proportion to the lithopone
giving a paint which will leave a correspondingly
thicker coat. The percentage of pigment in the
further polishing can be done.
Another object is to produce a paint which
paint may vary between 55% and 80% depending
on the materials used and the drying conditions
can be washed readily.

semi-gloss ‘after the paint has dried to a point
where it has lost its sheen.
A paint embodying the invention is hereinafter

1 The lithopone (a coalescent precipitate of
ZnS and BaSO/i) and the aluminum silicate
. (AlSiOa‘) together form the'pigment of the paint.
The lithioponeris a rather heavy pigment giving a
hard,.relatively thin coat. Since it is desirable
to havethe coat ofpaint fairly thick, and still not
have the paint too heavy, a relatively light pig
ment such as aluminum silicate is added.
The
be used without giving a waxy or greasy ?nish
which would retard drying and be di?icult to
repaint. The wax improves the washability of
the painted surface and gives a surface which
can be washed without disturbing the design.
The vehicle of the paint comprises ?atting
varnish and heat treated linseed oil. Like the
pigments, the relative quantities of oil and ?at
ting varnish may be varied. The oil may be
varied from 5 to 12 percent and the varnish cor
respondingly varied from 25 to 15 percent. Vary
ing the proportion of oil and varnish varies the
degree of polish obtained by brushing or rub
bing.
By ?atting varnish is meant a varnish which ~10
dries to a uniform dullness.
Such a varnish
may be composed of 10% soya. oil,_ 10% tung oil,
15% East India gum, and 65% mineral spirits.
The oil used is prepared by heating a raw
linseed oil to a temperature of 500 to 600° F., 45
maintaining it at that temperature for a short
period and allowing the oil to cool gradually.
‘The above formula gives a very thick white
paint to which color must be added to obtain the
desired shade. Also the paint must be thinned
by adding one to two pints of turpentine or
other volatile solvent to a gallon of paint. The
amount of turpentine added depends upon the
surface to be coated as well as the drying condi
tions desired.

Paints other than white may be made directly
by using a suitable colored organic or inorganic
pigment, such as iron oxide (FezOz), para reds,
chrome yellow (PbCrOr), yellow or blue lakes,
Cl etc., the essential condition being the covering
property of the pigment'and its ability to leave
a thick coating of paint on the painted surface.
The above described paint when properly mixed
