PROCESS OF TREATING CONCRETE STRUCTURES TO WATERPROOF AND INSULATE THE I SAME.

Processes of Treating Concrete Structuresto Waterproof and Insulate the Same, ofwhich the following is a specification.
My invention relates to a process of treating concrete hulls of ships or vessels, to
render the same water-proof and electrically insulated for the reception of copper or anti- 'fouling or other paints.
' In accordance with the preferred embodiment of my process, the concrete hull, after the removal of the forms, is treated witha suitable cement wash, applied by a brush or trowel, in order to provide a smooth outer surface. This smooth outer surface is allowed to thoroughly dry and harden. I then apply to this hardened surface a bituminous wash, which is preferably laid on by means of a large brush. This bituminous wash preferably consists of 20 parts by weight of asphaltum, 20 parts by weight of coal tar pitch, and 60 parts by weight of coal tar spirit. This coating or wash is allowed to dry for about three to four hours.
After the bituminous wash is thoroughly dried, 1 next apply a coat of bituminous paint. This bituminous paint preferably comprises 15 parts by weight of asphaltum, 15 parts by weight of coal tar pitch, 15 parts by weight of heavy tar oil, 20 parts by weight of benzol or light tar oil, 3 parts by weight of linseed oil, 2 parts by weight of litharge, and 3Q partsby weight of oxid of iron, .or other suitable pigment.
v The bituminous paint is used as a priming jand will readily attach to the bituminous wash, which is first applied. This bituminous paint will serve as an insulator for copper paint or other anti-fouling paint, which may be applied as a final coat.
I have found that the bituminous solutionor wash will penetrate to a considerable depth into the structure of the concrete, thus water-proofing it to a high degree.
The bituminous paint will also further aid in water-proofing the concrete, and further serves as an insulator for a copper paint, and
ply to the surface, for protection against fouling or to improve the appearance of the By the above means a reliable adhesion of the paint to the concrete can be assured.
It is obvious that either or both sides of Patented Apr. 9, 191%.
Application filed December 19, 1917. Serial No. 207,909.
the concrete structure, may be treated or coated, in accordance with my process.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that changes in the proportions of the several ingredients and order in which the steps are carried out may be varied without departing from the spirit of the invention or the scope of the subjoined claims.
Having thus described my invention, I claim:
1. The herein described process, which consists in applying a cement' wash to the surface of a concrete structure for providing allowing the bituminous wash to thoroughly dry, applying a bituminous insulating paint to the surface previously treated with the bituminous wash,-and allowing the bituminous insulating paint todry.
3. The herein described process, which consists in applying a bituminous wash to a concrete structure to water-proof the same,
said bituminous wash comprising a bituminous material and coal tar spirit; allowing bituminouswash to dry; applying a bituminous insulating paint .to the surface previously treated with the bituminous wash,
said paint comprising a bituminous material, an oil, litharge, and o'xid of iron; and, allowing the bituminous insulating paint to dry.
4. The herein described process, which consists in applying abituminous wash to a ,a smooth surface, allowing the wash thus E 22 i menses concrete structure to Water-proof the same, litharge, and oxidof iron; and allowing the said bituminous Wash comprising asphaltum, bituminous insulating paint to dry. 1(1) coal tar pitch, and coal tar spirit; allowing In testimony whereof I a my signature the bituminous Wash to dry; applying a in presence of two Witnesses.
bituminous insulating paint to the surface ALBERT C. HOLZAPFEL. I previously treated With the bituminous Witnesses: wash, said paint comprising asphaltum, coal RICHARD HorTELnB,
