WHITEWASH FORMULAS

AMERICAN IDEAS. The following formulas are recommended by American agricultural experiment stations for whitewash for dairy and other farm buildings. They are taken from a list published in Hoad’s Dairyman:— 1. Mix 5()lb. hydrated lime with 8 gallons boiling water. Add .101 b. common salt and lib. alum dissolved in 6 gallons boiling water. Stir mixture we?*, adding 51b. cement. 2. Slake 101 b. quicklime in 2 gallons water, cover and let stand for an hour. Then add sufficient water to bring the mixture to thickness of thin cream. 3. Factory whitewash: (a) Beat up a 41b. rye flour in a pint of cold water, then add 1 gallon of boiling water, (b) Dissolve lib. of common salt in 2 quarts of hot water. Mix A and B then stir this into a, solution of 101 b. quicklime slacked in 2 gallons of water. 4. Weatherproof whitewash for exteriors: Slack 621 b. quicklime in 12 gallons of hot water, and add 21b. salt and lib. sulphate of zinc dissolved in 2 gallons of boiling water. To this mixture add 2 gallons of skim milk and stir well. 5. Slake quicklime with water, and add sufficient skim milk to bring to the consistency of thin cream. To each gallon add loz. of salt, and 2oz. of brown sugar dissolved in water. The germicidal value may be increased by adding jib. chloride of Ihnc to every 30 gallons of wash. 6. Slake quicklime with enough water to bring the solution to the consistency of thin cream, and strain through hessian. For a chicken house or barn where milk is not kept it is advisable to add 4oz. of some coal tar disinfectant to every gallon of mixture. 7. An ounce, of alum tu a gallon of whitewash will prevent its rubbing off. A pint, of molasses to 5 gallons of whitewash makes the lime mure soluble, and causes the whitewash to penetrate farther into the wood. A pound of cheap bar soap dissolved in a gallon of water and added to 5 gallons of thick whitewash will give it a gloss like oil paint. A pint, of disinfectant is frequently added to each 4 gallons of whitewash.
