SALT LAKER WOULD
PRESERVE BUILDINGS
Makes Discovery That Will
Make Stone and Brick
Endure Forever.
no MORE DISINTEGRATI0N.
NO MORE R0TTING STONE
lmpervia Is the Preventative,
and It Is Among Greatest
Discoveries of Day.

~ Eoa!t Lascr mas invented something
that viii preserve stone and bricl;
buildings for ages. This invention. which
New York capital has taken hold of and
which will soon result in the formation
of company with q capital stock of
$l5o,000, speaks volumes for the work
of this Salt Lake man.
Through his ingenuity, buildings will
be prevented from crumbling, from
decay, from rotting. In other words
ranges, from the quarries of which the
stone used iii construction OF the build
lngs is obtained. His invention or dis
covery, whichever one is pleased to call
1t, will not only revolutionize the
building industry, but it will tend TO
make buildings as endurable as the
pyramids. Like most all other dis.
coveries it came by chance. Hero is
the story:
Story Of Impervia.
In the early part OF 1905; John Lol
I'm. owner OF the Lollin block in Salt
Lake City, requested the discoverer, j.
II. Hamlin. the well-known painter and
decorator of this city, to devise some
method OF treating tho stonework Of
his building so that it would not be
come discolored Mr.. Lollin, being n
practical business man, well versed in
building affairs, did not want to re-
sort to acid to clean the building, on
account of the certainty of the acid de-
.stroylng the durability OF the stone;
he did not desire the work cleaned by
the sandblast process on account of the
tendency to pit the surface and TO de-
stroy the sharp edges of the carving
which formed conspicuous feature of
the artistic front of his building. and
he objected to both of these methods
from the fact that they only left the
work in condition to undergo again, the
same process of discoloration and
decay.
Mr.. Lollin likewise objected to the
oil paint method OF protecting the work
in this way, as il did not have an af-
finity for stoncwork and would soon
peel off; also because it covered the
natural beauty and texture of the
stone.
Acting under the suggestions OF his
patron, who was Il valued customer,
and with no other idea in mind than
TO furnish frst-class piece of work in
this particular instance, Mr.. Hamlin be-
gan 10 experiment. with q view to pro-
ducing n material that would fill re-
quirements. He based his experiments
on the well-known fact that moisture
is the cause of all discoloration and dis
integration in stone and brick work,
etc The moisture entering into the
many tiny pores OF the brick OF stone
takes with it all soluble dirt, CRIME,
etc, which may happen to be on the
surface, and once on the inside of the
stone causes 1t to crack and chip.
After some experimenting Mr., Ham
lin produced material that seemed to
fill all the requirements and after de-
monstrating its properties to Mr.. Lollin
obtained his consent TO treating the
building with the new material. This
was done in March, 1905, and when
the building was cleaned three years
later tho material was found TO be in
Just as good condition as when first
bility Of the discovery, which has been
named "Impervia.'
After the completion Of the work
for Mr.. Lollin, tho idea that an tr-
tic1e of this nature would meet with
public approval dawned upon the dis
coverer. and he made further expert
ments with view to placing the ma
terial upon tho market. After much
experimenting he is now able to state
that he has perfected a material that
not only has a chemical affinity for
any substance OF gritty nature, but
one that is absolutely waterproof, and
is, more than anything else, liquid
grit or stone plating, that pormeates
Che pores Of the material TO which it
is applied and becomes even more hard
and durable than the material. Besides
perfecting "Tmpervia,' the discoverer
has perfected various specialties Of the
same general nature.
Is Liquid Grit.
As said, "Impervia" is liquid grit.
FOR plating either stone or brick. For
new work it absolutely preserves, and
Is transparent. 1t is a wellknown fact
that moisture causes all the discoloring,
decay and disintegrating of stone utter
it Is taken from the stratas or quarries
where nature placed it. Were moisture
stopped from penetrating the stone or
brick, all decay would stop. This "1m
pervia' does
1mpervia for new brick and stone is
semi transparent chemical compound,
not a paint, but rather q liquid stone
or plating. which permeates the pores
Of The material to which it is applied
and effectuallY prevents the entrance
Of moisture and the consequent staining
and disintegratiou, etc. BY its applica,
ton, the natural beauty and texture
of tho stone or brick is brought out
