News for the would-be intruder
in your house is the burglar-dis-
couraging device we have just found
that employs light and sound to
scare him away when he tries to
sneak in by window or door.
1t is lanternlike affair which is
merely set on the floor against
door or on its back under or to one
side of window. It will tip over
as the door or window is opened.
AS it tips it throws a searchlight
into the marauder's eyes and sounds
a loud alarm. If that scares him.
and he closes the door or window
and runs away, neither the light
nor the alarm will cease to function
until the lantern is raised from the
floor. Especially comforting in
child's room if you are at all wor-
ried about kidnapping
The assets of this alarm are
chiefly that it is portable, that it
requires no external wiring and can
be used at any door or window. 1t
cannot be reached from the outside
by a skillful lock-picker, and costs
S4,75. 1t can be used as a light
alarm only, by merly springing a
switch arm before you retire-in
case sudden loud noises are too
much for you, even as a signal you
are about to be robbed.
The switch is so adapted that the
device can be used without any
alarm at all, but merely as a port
able electric lantern for which there
are many uses about the home.
Cement paint came into being as
a product for coating porous sur
faces like stucco, concrete, stone
and plaster. 1t is meant to weather.
proof and waterproof your house
and-Within reasonable limits-it
does. But. besides all this, cement
paint is pleasing in color, durable
and has nice texture, so a lot of
people wanted to know if they could
use it for non-porous surfaces like
oil-painted masonry and tile roofs
and glazed brick.
The answer, until recently, was
that cement paint couldn't be ap-
piled except on those surfaces for
which it was intended. But now,
with the debut of a special kind of
priming coat, cement paint can be
used on any masonry surface. The
primer treats non-porous surfaces,
painted or unpainted, so that they
can hold a finish coat of cement
paint. 1t supplies the necessary
porosity and suction to bind the fin
ish coat to the wall. So you get
the effect of cement paint, although
you may not need its special attri-
butes other than effect.
The printing coat is applied to,
let us say, an integrally water
proofed, mooth-troweled, or very
dense stucco retaining or founda-
tion wall, which is practically nom
porous. without any 'wetting down" "
That means not much time is re-
quired to prepare the surface of the
spot you want to paint. Just see it
is free from seepage of water and
brush off loose bits of oil paint or
clumps of dust.
With a retaining wall you would
not have any glossy surfaces, but If
you should be trying to paint tile,
for example, it is we'll to dull the
gloss by sanding. Same with metal
or glazed brick. If there is a coat
of glue bound water paint or white
wash on the surface, you will have
to remove that, too.
The primer is easily mixed by
stirring in 5 pounds of printing
powder to S or pints of water
depending upon the porsity of the
surface. Then put on the prim-
ing coat with brush or spray. Five
pounds of this primer will cover
from 200 to $50 square feet.
The cement paint goes over this
printing coat in the same way it Is
applied to porous surfaces, except
