In the preparation of ready mixed paints, it is customary, as mentioned before, to prepare a suitable base of white and to add proper amounts of prepared stainers to produce the required tints.
For dark colors, such as the reds, greens, and browns, a suitable base of dark pigments is made and thinned in the regular way.
Yacht white, ready mixed paint: mix thoroughly and after mixing strain.
25 pounds of white lead (in oil),
25 pounds of white zinc ( in oil),
4 gallons raw linseed oil,
1 pint turpentine,
1 pint liquid dryer.
Add a trifle of Prussian blue to produce a pure white. This paint is suitable for all exteriors, and exposed places and stands moisture and salt air to a remarkable degree.
To prepare inside white of the same quality, change the 4 gallons of raw linseed oil to a mixture of 2 gallons of raw linseed oil and 2 gallons of turpentine.
One pint of solution, No. 1, mentioned under ready mixed paints, may be added to hold up the pigments and make the paint work more smoothly, without detriment.
12 pounds of white zinc, (in oil), 4 pounds of white lead, (in oil),
2 pounds of Paris white, (dry), 1 1-2 gallons raw linseed oil, 1-8 gallon liquid dryer,
1-2 gallon solution, No. 1.
For inside white of the same quality, let the thinners be 1-2 raw linseed oil, and 1-2 turpentine, instead of all oil.
In the preparation of the various ready mixed tinted paints, first make a base of white, which will answer for outside white.
Base White Number One is prepared by mixing thoroughly:
30 pounds of white lead, (in oil),
30 pounds of white zinc, (in oil),
4 gallons of raw linseed oil,
1-4 gallon of turpentine,
1-2 gallon of solution No. 1,
1-2 ounce of prussian blue, (in oil),
1-4 gallon of liquid dryer. If too heavy, thin by adding a little more raw linseed oil.
Base White Number Two is made by mixing as above:
10 pounds of white lead, (in oil),
10 pounds of white zinc, (in oil),
10 pounds of Paris white,
2 1-2 gallons of raw linseed oil,
1-4 gallon of liquid dryer,
1-2 gallon of solution No. 1. Thin with benzine if too heavy. The Paris white must be finely bolted and allowed to soak in the linseed oil before adding the other pigments.
