Important: Safety Warning
This page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.
This page directs the use of hazardous substances — such as benzine, gasoline, lye, or strong acids — for household tasks. These materials are highly flammable, corrosive, or poisonous, and the practices described have caused fires, burns, and poisonings.

Adhesives, Paints, and Varnishes: Priming
Priming coats should be thin, and well brushed out, but it is a mistake to have them too thin.
Putty. After the priming coat is thoroughly dry, putty up all nail holes, dents, cracks, and other defects in the surface with a pure linseed oil putty composed of equal parts of white lead and whiting.
Nearly all the putty sold at present is made of other oils than linseed (chiefly products of petroleum) and ground cliffstone sand. The use of such putty is the explanation of the yellow nail holes and cracks so often marring the appearance of what is otherwise good work.
The addition of 1 part of powdered litharge to 5 parts each of white lead and whiting in the composition of the white lead putty above specified is permissible and, where convenient, advised. The addition of the litharge assists the drying and hardening of the putty.
Second Coat. One hundred pounds of pure white lead; 4 to 5 gallons of pure raw linseed oil; gallon of pure turpentine; 1 pint of pure turpentine japan.
In winter and damp weather from pint to pint additional turpentine japan should be used. Third Coat. One hundred pounds of pure white lead; 4 to 4+ gallons of pure raw linseed oil; 4 gallon of pure turpentine; 1 pint of pure turpentine japan.
In winter and damp weather from pint to pint additional turpentine japan should be used. Specifications for New Work Inside.-Before Painting. As above, Knot Killing. As above.
Priming Coat. - One hundred pounds of pure white lead; 5 to 6 gallons of pure raw linseed oil; 2 gallons of pure turpentine; 1½ pints of pure white turpentine japan.
On white pine, poplar, and basswood (which more readily absorb oil) use 6 gallons of linseed oil.
On yellow pine, spruce, and hemlock use 5 gallons of linseed oil. In winter and damp weather from pint to pint additional turpentine japan should be used. A range of from 5 to 6 gallons of linseed oil has been specified to allow room for the painter's judgment; there may be circumstances where as much as 7 gallons of linseed oil to 100 pounds of white lead may be used to advantage, but they are rare, and as a rule 6 gallons may be taken as a safe maximum.
The painter may in some special cases find it advisable in the priming coat to increase the quantity of turpentine from gallon to 1 gallon, but where this is done a corresponding decrease should be made in the specified amount of linseed oil.
Priming coats should be thin, and well brushed out, but it is a mistake to have them too thin.
