A New Fire and WaterProof Paint.

Manufacturer and Builder 5, 1872

It is well known that soap is composed of oil, fat, etc., and a base, and that paint as it flows from the brush of the craftsman, consists of some finely powdered substance mixed with oil. This substance, whether white-lead or any metallic oxide used for coloring material, supplies the base, which combined with the oil used, eventually causes paints thus made to become soap; time performing the same process that is effected by heat in the soap-boiling establishment. The consequence is, that time paint, after this action has taken place, will wash off. Experience has moreover shown that atmospheric influences will rarely be resisted longer than a year, and if exposed to the sun's rays, blisters will form which chip and peel off. If oilpaint be applied to a fresh surface of wood, the oil frequently sinks in, leaving the pigment loosely adherent in the form of a friable powder; while if used on a metallic surface, as soon as the oil dries the crust formed will crack and peel away, and if a fresh coating be not applied the metal corrodes. The admixture of white-lead has been found not to answer the purpose, as it appears to yield in the course of time a part of the oxygen it contains, and so acts in the same way as the air would if it had free access to the surface of the metal.

A paint, however, has lately been introduced into the market by Messrs. S. L. Merchant & Co., of No. 76 South street, in this city, which is designed to entirely obviate all of the abovementioned difficulties. It contains silica in a peculiar form, extracted from a mineral of volcanic origin, which renders the surface covered by it indestructible and unchangeable, and in fact causes the paint to petrify. The nature of silica is the same as that of flint, and it will be readily seen that paint prepared with it will afford a covering perfectly water and fireproof, which will never crack, and always retain its luster, the silica itself having no chemical action whatever.

It is simple in its application, dries hard in from six to eight hours, according to time state of the weather, and incorporates itself with the iron, so that any kind of paint, of any color, can be laid on over it. It is strongly recommended for priming and painting all kinds of out and in-door iron and wood-work, such as iron lighthouses, railway bridges, girders, boilers, tanks, railings, iron masts, yards, spars, gasworks, etc., etc., also as a priming for teak wood in India, likewise for mining plant, telegraph posts, etc. This paint will be found admirably adapted for painting the frames, beams, ani plating of iron ships. It works tool, and does not take nearly so long in going down, and has little or no smell. It will stand repeated washing. It preserves iron, wood, etc., from rust and decay; neither heat, moisture, nor frost has any effect upon it It will be found to set quickly, and dry as hard as marble. It closely finds its way into time structure of iron and wood, and bites (so to say) into the very body of the material it covers, and consequently never peels off. It possesses great firmness, being ground with prepared drying oil by heavy steam power, and is as fine as artists' colors; the particles are thoroughly diffused and incorporated, which is not the case with powdered colors when mixed with oil unground, which are always more or less liable to flake off, blister, or wash away from the surface of iron or wood-work. Its covering quality or body is much greater than that of ordinary paints, and it combines durability with a highly-finished appearance. It is claimed to be the best paint, from its hard body ground, for coach and railway carriage builders, also for flatting purposes, that can be produced.

It possesses great durability, will not require renewal for many years, is applicable and effective in all parts of the world, under every change of climate, and is not affected by exposure to sea air or the hottest sun. It is invaluable for maritime purposes, as it has the property of resisting the action of salt water. On iron, and many other substances, one coat will often be found sufficient, and two coats will be found equal to three or four of ordinary paint, by which a great saving in color and labor will prove its economy.

We are assured by practical painters that the covering properties of time silicate paints are nearly double that of common paints; that, combined with its lasting qualities and brilliancy of color, render it the bestlooking and most economical of all paints. It is supplied in all colors, and is used in precisely the same way as ordinary paint.
