Patching Of Concrete
Floors Easy Task
Ry HILSON MUNSEY.

Patching cement floors always is
q problem, and it Is an expensive
operation to take up an old Aoor
and relay it. There is a special
patching cement that will solve the
problem of worn cement surfaces,
either in the basement or on the
factory floor. This patching cement
is sold ready-prepared, except for
the addition Of water. No sand or
other cement are required with the
mixture This resurfacing material
can be applied in thickneSses from
three -eighths to one-half inch, and
the patch can be walked on safely in
five hours or a truck can be driven
over it in "a hours,
In applying the patch, the first step
Is to chip out groove around the
area to be patched. This cement
cannot be finished off with a feath-
cred edge. 1t must be butted against
the edge OF the old cement flooring.
After that, all grease spots must be
Clipped out and the loose material
carefully brushed away. 1t may, in
some cases, be necessary to use
muriatic acid If this is done the
area must be washed thoroughly
with water to remove all traces of
the acid before the mixture is
applied.
When the patching area has been
prepared, 1t must be sealed with a
special primer supplied by the manu-
facturer. This sealer is included
In each container of the cement
The next step is to allow the primer
to dry thoroughly and then some
of the cement should be brushed
over the patching place. This appli-
cation of the cement must wet thor
oughly the area that is being worked
on. The next step is to pour in
enough of the cement mixture to
cover the area to the level of the
surrounding floor Then this is
leveled off and troweled smooth.
After it has been allowed to set for
five hours it is ready for ordinary
foot trafiic. 1t will not shrink away
at the edges and it cannot be sep
arated from the original cement
flooring. To cover a patch of one
square foot Al pounds of the mix
ture are needed.
Watering the Lawn.
When dry weather comes along
the lawn will begin to take on
brown and green appearance. This
means lack of water that must be
supplied artificially If the green
smoothness is to be maintained. A
sprinkler that is self-propelling can
be bought, which would be q big
improvement on a hose that must
be hauled around by hand to the
detriment of the clothing and the
annoyance of the victim who is
elected, to direct its wavering ad-
vance.
This sprinkler is designed prin-
eipally for large areas of lawn. The
motive power is supplied by the
pressure of the water On the base
of the sprinkler is drum which
holds $50 feet of cable. This cable
Is unwound to the required length
and then the water pressure turns
the cable drum and slowly winds the
sprinkler unit back to its starting
point. When it arrives there the
water supply is shut off.
The motive power of the water
pressure is capable of pulling 125
feet of one inch hose full of water,
but 1t is not recommended for use
with longer lengths. The unit can be
moved easily from one position to
another.
The unit in operation travels from
IS to so feet an hour, so that the
lawn gets thorough soaking in
stead of superficial sprinkling
that brings the grass roots close to
the surface to be burned off when
the midsummer sun strikes them
