LEAD PAINT the fire extinguisher WHEREVER unpainted surfaces are ex posed to the atmosphere, they burn just as surely as when a match is applied. This burning, or combustion, involves oxidation, during which oxygen is taken from the sur rounding air. There are three kinds of com bustion: almost instantaneous, or explosion; rapid, or fire; and slow, or rot. Slow com bustion is destroying millions of houses, rot ting wooden porch columns, window sashes, and exterior walls. You can keep the wooden surfaces of your house safe from slow combustion, or rot, by keeping them covered with a constantly maintained film of lead paint that is imper vious to air and moisture. Thousands of master painters and house owners use lead paint made of Dutch Boy white-lead. It makes a tough, elastic and waterproof film that sticks to the surface, does not crack and scale, and has great hiding power. For exterior work use a combination of Dutch Boy white-lead and linseed oil. For flat finishes (usually desired for interior painting) mix Dutch Boy white-lead with Dutch Boy flatting oil. In either case the paint can be tinted to any color desired. Dutch Boy white-lead and flatting oil, either white or tinted, makes a paint that gives particularly finishes that rest the frequent washing. soft, beautiful flat eye and withstand We will be pleased to send you a new booklet, "Painting-Protective and Decora tive" that contains color plates of house exteriors and interiors and also of interest ing and unusual artistic wall finishes that can be obtained with paint.
