Cob Farmer's Bulletin #1500 on Weatherproofing Earth

Tue Mar 2 22:51:53 CST 1999

Hi  Mudder's, E-Shippers and Strawbalers,

I finally located a hard copy of Farmers' Bulletin # l500   U.S.
Department of Agriculture, Washington, DC, l926, rev. l937 in the Gov
Publications at the UNM library and want to share a few goodies with
you. These are recipe's and formulas straight from the book.  We could
use some input from our resident lime expert, Harry, on their uses and
perhaps modifications if it is necessary--good luck and if anyone uses
the materials noted, let us know how they worked out.

Casein White Wash-Highly recommended, will not chalk or rub and is
weather resistant.
Soak 5 lbs casein in about 2 gal water ( preferably hot) until
thoroughly softened (about 2 hrs); dissolve 3 lbs trisodium phosphate in
about 1 gal of water and dissolve the casein in this solution;  prepare
a thick cream by mixing 50 lbs ( 1 sack) of hydrated lime in about 7 gal
of water, stirring vigorously; dissolve 3 pints of formaldehyde in about
3 gal of water;  when the lime paste and casein solution are both
thoroughly cool, slowly add the casein solution to the lime , stirring
constantly.  Just before applying, slowly add the formaldehyde to the
mixture, stirring constantly and vigorously.  Care must be taken not to
add the formaldehyde too rapidly as it may cause the casein to jell,
thus spoiling the batch. The cold lime paste produced by carefully
slaking and screening 38 lbs of quick lime may be substituted for the
hydrated lime.  Do not make up a greater quantity of this wash than can
be used in one day. Borax may be substituted for the trisodium
phosphate, but it does not produce so durable a whitewash

Weatherproof  Whitewash
Slake 62 lbs (1 bushel) quick lime with 12 gal hot water; dissolve 2 lbs
common table salt and 1 lb zinc sulfate in 2 gal boiling water and add
to the lime mixture, then add 2 gal skimmed milk; stir thoroughly.

Lighthouse  Whitewash
Slake 62 lbs (1 bushel) quick lime with 12 gal hot water; dissolve 12
lbs rock salt  in 6 gal of of boiling water and add to the lime mixture,
then add 6 lbs portland cement; stir thoroughly.

Government Formula
Slake 1/2 bushel (31 lbs) of quick lime with boiling water, keeping it
covered during the process; strain it and add a peck of salt dissolved
in warm water; boil 3 lbs ground rice in water to a thin paste; dissolve
1/2 lb of powdered Spanish whiting and a pound of clear glue in warm
water.  Mix these well and together and let the mixture stand for
several days.  Keep the wash* thus prepared in a kettle or portable
furnace and apply as hot as possible.

* One ounce of alum added to a gallon of lime whitewash increases its
adhesive quality

 Flour paste answers the same purpose, but a preservative such as zinc
sulfate should be added

One pint of molasses added to 5 gal of whitewash renders the lime more
soluble and causes it to more deeply penetrate wood or plaster.

A pound of cheap bar soap dissolved in a gallon of water and added to
about 5 gal thick whitewash will impart a gloss like that of  oil paint.
