Home-made washes for fences and out-buildings may be made by various combinations of lime and grease. The following are good formulas : —
1. Slake fresh quicklime in water, and thin it to a paste or paint with skim-milk. The addition of two or three handfuls of salt to a pail of the wash is beneficial.
2. Two quarts skim-milk, 8 ounces of fresh slaked lime, 6 ounces of boiled linseed oil, and 2 ounces of white pitch, dissolved in the oil by a gentle heat. The lime must be slaked in cold water and dried in the air until it falls into a fine powder ; then mix with \ part of the milk, adding the mixed oil and pitch by degrees; add the remainder of the milk. Lastly, add 3 pounds of the best whiting and mix the whole thoroughly.
3. Slake 1/2 bushel of lime in boiling water, keeping it covered; strain and add brine made by dissolving 1 peck of salt in warm water, and 3 pounds rice flour, then boil to a paste ; add 1/2 pound whiting and 1 pound of glue dissolved in warm water. Mix and let stand for a few days before using.
4. In a covered vessel slake the best quicklime, then add a mixture of skim-milk and water, and mix to the consistency of cream ; then add 20 pounds of alum, 15 pounds of potash and 1 bushel of salt to every 100 gallons of the liquid. If white paint is desired, add to the above 6 pounds of plaster of paris.
For damp walls.
5. Three-fourths pound of hard soap to 1 gallon of water. Lay over the bricks steadily and carefully with a flat brush, so as not to form a froth or lather on the surface. After 24 hours mix \ pound of alum with 4 gallons of water ; let it stand twenty-four hours, and then apply it in the same manner over the coating of soap. Apply in dry weather.
6. One and one-half pounds resin, 1 pound tallow, 1 quart linseed oil. Melt together and apply hot, two coats.
Water-proofing paint for leather.
7. One-half pound of shellac, broken into small pieces in a quart bottle ; cover with methylated spirit (wood alcohol), cork it tight, put it in a warm place, and shake well several times a day ; then add a piece of camphor as large as a hen's egg ; shake again and add an ounce of lampblack. Apply with a small paint brush.
8. Put into an earthen jar \ pound of. beeswax, 1/2 pint of neat's foot oil, three or four tablespoonfuls of lampblack, and a piece of camphor as large as a hen's egg. Melt over a slow fire. Have both grease and leather warm, and apply with a brush.
9. One pint of linseed oil, 1/2 pound mutton suet, 6 ounces of clean beeswax, and 4 ounces of resin; melt and mix well. Use while warm with a brush on new boots or shoes.
For cloth for pits and frames. (See page 200.)
10. Old pale linseed oil, 3 pints ; sugar of lead (acetate of lead) 1 ounce ; white resin, 4 ounces. Grind the acetate with a little of the oil, then add the rest and the resin. Use an iron kettle over a gentle fire. Apply with a brush, hot.
11. Dissolve 13/4 pounds of white soap in 1 quart of water; in another quart of water dissolve 11/2 ounces of gum arabic and 5 ounces of glue. Mix the two liquids, warm them, and soak the paper in it and pass through rollers, or simply hang it up to dry.
To Prevent Metals From Rusting.
12. Melt together 3 parts of lard and 1 part of powdered resin. A very thin coating applied with a brush will keep stoves and grates from rusting during summer, even in damp situations. A little black lead can be mixed with the lard. Does well on nearly all metals.
To Prevent Rusting Of Nails, Hinges, Etc.
13. One pint of linseed oil, 2 ounces black lead ; mix together. Heat nails red-hot and dip them in.
To Remove Rust.
14. Heavily rusted iron may be cleaned by immersing it in a bath (not too acid) of chlorid of tin, for twelve to twenty-four hours. After removing, rinse in water and then in ammonia.
15. Rusted steel may be brushed with a paste of 1/2 ounce cyanide potassium (poisonous), \ ounce castile soap, 1 ounce of whiting, and water. Then wash in 2 ounces water containing 1/2 ounce cyanide.
Amount of paint required for a given surface.
It is impossible to give a rule that will apply in all cases, as the amount varies with the kind and thickness of the paint, the kind of wood or other material to which it is applied, the age of the surface, etc. The following is an approximate rule : Divide the number of square feet of surface by 200. The result will be the number of gallons of liquid paint required to give two coats ; or divide by 18, and the result will be the number of pounds of pure ground white lead required to give three coats.
