Whitewashes for Stock Buildings.

I desire whitewash recipes which have given durable results on outbuildings.

It is so desirable to make outbuildings neat and clean, and so important to keep trees from sunburning, etc., that a durable whitewash as cheaply and easily made as possible is very important.  The following are commended:  No. 1 — To half a bucketful of unslaked lime add 2 handfuls of common salt, and soft soap at the rate of 1 pound to 15 gallons of the wash.  Slake slowly, stirring all the time.  This quantity makes 2 bucketfuls of very adhesive wash, which is not affected by rain.  No. 2 — Whitewash requires some kind of grease in it to make it most durable.  Any kind of grease, even though it be old and partly spoiled, will answer all right, though tallow is best.  The grease imparts to the whitewash an oil property the same as in good paint.  Tallow will stay right on the job for years, and the cheapest of it will do.  In order to prepare this grease and get it properly incorporated into the white wash, it is necessary to put the grease in a vessel on the stove, and boil it into a part of the whitewash so as to emulsify it and get it into such condition that it can be properly incorporated with the whitewash mixture.  No. 3 — For every barrel of fresh lime, add 16 pounds of tallow, 16 pounds of salt and 4 pounds of glue, dissolved.  Mix all together and slack; keep covered, and let stand a few days before using.  Add water to bring the right consistency to spread readily.  For nice inside work strain it.  When less than a barrel of lime is used, the quality of the wash does not seem so good.  It is better to apply hot, but it does well cold.

Government Whitewash.

What is the government recipe for whitewash?

“Take a half bushel of well-burned, unslaked lime, slake it with boiling water, cover during the process to keep in steam, strain the liquid through a fine sieve or strainer, and add to it 7 pounds of salt, previously dissolved in warm water; 3 pounds of ground rice boiled to a thin paste and stirred in while hot; half a pound of Spanish whiting and 1 pound of glue, previously dissolved by soaking in cold water, and then hanging over in a small pot hung in a larger one filled with water.  Add 5 gallons of hot water to the mixture, stir well and let it stand for a few days, covered from dirt.  It should be applied hot, for which purpose it can be kept in a portable furnace.  A pint of this mixture, if properly applied, will cover a square yard.”

Whitewash for Spray Pump.

Can you give a recipe for a durable whitewash which can be prepared simply and in large quantities?  The whitewash will be applied with a spray pump.

To 25 pounds of lime, whole, slacking with 6 gallons of water, add 6 pounds of common salt and 1 1/2 pounds of brown sugar.  Stir and mix well and allow to cool.  When cool stir in 1 ounce of ultramarine blue.  Then add 2 gallons of water, and sprinkle and stir in 2 pounds of Portland cement.  If two coats are to be applied, add 1 more gallon of water.  Strain for work on smooth surface.
