IMPROVEMENTS IN THE MEANS FOR CURING DAMP WALLS OR MASONRY OF HOUSES. AND OTHER STRUCTURES
Year: 1884

page_text: I, EMIL CAPITAINE, of 89 Chancery Lane, in the County of Middlesex, Engineer,
do hereby declare the nature of the said invention for "IMPROVEMENTS IN THE
MEANS FOR CURING DAMP WALLS OR MASONRY OF HOUSES. AND OTHER STRUCTURES,"
to be as follows:-
33
The present invention relates to the manufacture of a composition by the use of
which the dampness of walls or masonry may be got rid of even when the damp-
ness arises from saltpetre being contained in the stone or other material of which
the wall or masonry to be treated, consists.
The composition or preparation is made by intimately mixing together the
following ingredients in the several given proportions (or thereabouts) taken by
volume or measure, that is to say:—
1
of heated sand
21/ purified beech wood ash
slaked lime with a little pulverised lime
green vitriol
"
"
"
33
linseed oil
8
» syrup of sugar, and
8
"B
chloride of calcium.
The composition so obtained possesses the quality of attracting the moisture
that may be present in its immediate vicinity. Thus, if a suitable quantity of this
composition be applied to the damp part of a wall, preferably by placing it within
a hole or recess made in the wall for the purpose, in from four to six weeks the
whole of the dampness will be eradicated and the wall maintained permanently
dry, as has been demonstrated by numerous trials. In the case where saltpetro is
present and the dampness arises from changes of temperature, the saltpetre becomes
crystallised whilst the liberated moisture is absorbed by the atmosphere.

I, EMIL CAPITAINE of 89 Chancery Lane in the County of Middlesex, Engineer,
de hereby declare the nature of the mid invention for " TUPROVEMENTS IN THE
MEANS FOR CURING DAMP WALLS OR MASONRY OF HOUSES AND OTHER STRUCTURES"
a communication to me from abroad by August Kothe of Hanover in the German
Empiro and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-

MEANS FOR CURING DAMP WALLS OR MASONRY OF HOUSES AND OTHER STRUCTURES"

The present invention relates to the manufacture of a composition by the use of
which the dampness of walls or masonry may be eradicated even when the damp-
ness arises from saltpetre being contained in the stone or other material of which
the wall or masonry to be treated, consists.
The composition or preparation is made by intimately mixing together the
following ingredients in the several given proportions (or thereabouts) taken by
volume or measure, that is to say:-
21/2
of heated sand
»
purified beech wood ash
1½ " alaked line with a little pulverised lime
» green vitriol
7. linseed oil
»
» syrup of sugar and
chloride of calcium.
The composition so obtained possesses the quality of attracting the moisture that
may be present in its immediate vicinity. Thus if a suitable quantity of this
composition be applied to the damp parts of a wall by introducing the same within
a hole made therein for the purpose, in from four to six weeks the whole of the
dampness will have been eradicated and the wall maintained permanently dry as
bas been demonstrated by numerous trials. In the event of saltpetre contained in
walls becoming moistened by reason of changes of temperature, the saltpetre
crystallises on the surface of the applied composition whilst the liberated water is
absorbed by the atmosphere.
Having now particularly described and ascertained the nature of said invention,
and in what manner the same is to be performed, I declare that what I claim is
The curing or drying damp walls or masonry by means of the application of a
composition made substantially in the manner described, and applied at the parts
it is required to cure, the said composition having the property of crystallising the
Baltpetre contained in damp walls and liberating the water substantially as
described.
