Show SOME information ABOUT PAINT paints are of three general classes linseed asphalt and coal tar and the natural hydrocarbons linseed linseed is generally consid erea except by experts as the ideal vehicle for paint this is far from being true linseed and red or white lead if pure make a fairly good paint but a long way from ideal linseed is a vegetable material and like all vegetable matter contains moisture moisture is death to paint it not only hastens oxidization decay or rust but causes pinholes in linseed paint through shrinkage and evaporation which allows moisture and air to penetrate linseed lin seed forms a gum which hardens until it becomes brittle and peels off or blisters carrying the pigment or paint body with it its mixture with the paint pigment is mechanical not chemical a vital difference the mater material lal is simply held in suspense linseed settles away from the pigment which makes it necessary to stir th the paint vigorously before applying or part will be too thin and part too thick it is expensive and finally what is a still more serio serious us matter pure linseed oil pure turpentine or pure pigments cannot be procured by the average person like many other manufactured goods nowadays they are not supplied pure to the trade it would take a special order direct to some responsible manufacturer to get these articles in the pure state like other traditions boiled balled oil and white or red lead or red ochre achre iron oxide or zinc white have been handed down to us by our forefathers as the paint to use with no other reason than that they have been used since time immemorial and so must be good asphalt and coal tar asphalt and coal tar paints are legion the woods are full of them they are mostly frauds in fact about the greatest bluff in the business world is the average coal tar and asphalt paint the virtue if it is such mostly dwelt on by the sellers of these paints is cheapness Is anything cheap that is not what it purports to be the most of them are not fit to be dignified by the name of paint they possess no elasticity when the thinner or vehicle evaporates they soon become brittle and drop off or if subjected to slight heat will run it is actually a waste of labor which is money these days to apply these cheap black paints to any surface ideal paint the ideal paint is one in which the base and the vehicle make a perfect union not a mechanical one a solution not a suspension it should be elastic expand and contract with the substance covered should spread evenly and smoothly and above all form a continuous coating one that completely covers the surface with no pinholes or cracks which allow the admission of air or moisture thereby causing decay of wood or paper and rust of metal natural hydrocarbons hydro carbons the utah utah hydrocarbons gilsonite and tabb come nearer perhaps making ideal preservative paints than any other substance known except in some cases where extremely expensive materials are used for certain purposes these hydrocarbons hydro carbons are formed from oil coming in from below and filling fissures in the earth and hardening under pressure and time and are mined in a pure state they are found nowhere else in the world outside of utah and are a unique class by themselves in the order of excellence gilsonite comes last its origin was oil it is somewhat inclined to be brittle but makes a beautiful glossy paint and a good second class varnish is next although if it were not so difficult to manipulate it would probably equal any other it is called mineral rubbers as it cuts like hard rubber and smells like rubber when burning it is quite elastic and under distillation yields valuable oils 1 Tabb the latest discovery of these hydrocarbons hydro carbons is by far fa r the best it was formed from a mixture of the oil that formed with erite as a base the latter is called mineral wax and Is a rare and expensive substance owing to this combination tabb is peculiarly adapted for paints it is used also in making rubber mats the rubber made from it is astonishingly like the tree rubber it is somewhat elastic and very pliable used as a paint if properly applied preferably two thin coats on a clean surface it will last for years As a preservative coating for wood iron cement canvas paper and prepared roofing it is not excelled it is especially adapted for boiler and stack purposes it is not affected by heat or moisture acids or al kalies retains its elasticity indefinitely and is a nonconductor non conductor of electricity how to apply pa paint I 1 nt in applying all of the above paints the surface to be covered should be cleaned from dirt and rust and be dry apply preferably in two thin coats allowing the first to thoroughly dry before applying the second if only one coat is to be applied it should be put on considerably thicker passing the full brush over the surface several times A large flat brush with stiff bristles should be used and when there is considerable surface like a roof to be covered a three or four knot brush can be used with straight handle or mop fashion the railways and smelters shelters sm elters use a spray pump for covering large surfaces which lessens the labor cost very materially hydrocarbon hydro carbon paints are ae generally made ready to use making them more convenient than the linseed paints and owing to the necessity of having a thinner or I dryer in all paints i 1 e a liquid to thin the paint down so it will flow readily under the brush and evaporate after application so that the paint will dry and harden it is nece necessary scary to keep the package airtight air tight except when using or the paint will thicken thinners are turpentine benzene petroleum distillate til late gasoline etc owing to the fact that turpentine is largely adulterated with ros rosin 1 n it should not be used unless its purity is absolutely sure the plan generally adopted in using linseed paints is to mix up the quantity desired to be used at the time if too much is mixed up at one time it will dry out and form a hard gum in hydrocarbon hydro carbon paints draw off by a faucet if in a barrel into a paint bucket the amount required from time to time keeping the barrel or other receptacle closed in cold weather it is better to keep the paint in a fairly warm place as it draws off better and works better under the brush |
