Improvements in or relating to Damp-proof Paints or the like.
A communication from GUILLAUME PHILIPPs, of Brussels, in the Kingdom of
Belgium.
1 ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a material or compound which may be used as a
covering or coating for protecting surfaces against damp or as a damp-proof coinse
in walls or other structures or for other purposes.
Paints hitherto used have not been impermeable, and it has long been an object
of research to produce a paint which shall absolutely preserve surfaces from all
contact with moisture and the atmosphere.
The idea was to find a material entirely unaffected by air and capable of resisting
the passage of damp and air through its pores.
This invention, to which the name "Monopole" has been given, consists of a
compound of suitable proportions of "Damar-Batavia gum, turpentine, china-
clay, and pulverized graphite," prepared in the following manner;-
The Damar gum is boiled in twice its volume of turpentine down to a ten per cent.
concentration, and, after cooling, sufficient turpentine to dissolve the mass is added.
Subsequently, an intimate mixture of the resulting product with the china clay and
powdered graphite in a suitable mixing or kneading machine is made, and finally
the mixture is passed through a colour-grinding mill, when it is ready for
application either as a paint, for damp-proof courses or for other
purposes.

I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—

of research to produce a paint which shall absolutely preserve surfaces from all
contact with moisture and the atmosphere.
The idea was to find a material entirely unaffected by air and capable of resisting
the passage of damp and air through its pores.

the mixture is passed through a colour-grinding mill, when it is ready for application
either as paint, for damp-proof courses or for other purposes.
The proportions of the various ingredients may be varied according to particular
requirements; the following have however been found to give satisfactory
results viz.

The Damar gum is boiled in twice its volume of turpentine down to a ten per cent.

powdered graphite in a suitable mixing or kneading machine is made, and finally

either as paint, for damp-proof courses or for other purposes.
The proportions of the various ingredients may be varied according to particular
requirements; the following have however been found to give satisfactory
results viz.
For producing 1 kilo. after boiling
720 gr. of turpentine
150 gr. of Damar gum
90 gr. of china clay
100 gr. of pure graphite.
These proportions are given merely as an example and may be varied to suit
local and other conditions.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. An impermeable paint or material into the composition of which the above-
named materials enter.
2. An impermeable paint or material compounded of the materials above-named
and prepared according to the process as above-described.
3. The impermeable paint substantially as described.
