For all ordinary purposes about the home, paint falls into two great general classes determined by service conditions. Paint that is exposed to weather, to sun and rain and snow, as well as to extreme temperature variations, must be prepared and applied so it can withstand those conditions. On the other hand, paint that is largely protected by its location inside a house is formulated quite differently. We will, however, reserve interior painting for the next chapter and devote this one to exterior house painting.
The natural, first question to arise in regard to house painting is that of when to paint. Its answer is dictated by the need for a dry surface. The best time for exterior painting is in the summer or fall, when exposed surfaces have had a chance to dry well after the winter's snow and the spring rains. The hot summer sun will have removed all moisture, leaving the surface in good painting condition. In case of rain, allow sufficient time for drying; a few hours of sunshine is not enough. If practicable, do not start painting until the sun has risen, so that the night's moisture will be removed.
The advantage of pre-winter painting is that excessive drops in tempera- ture are not to be feared. When the thermometer registers 45°F. or under, no exterior painting should be done. At low temperature, moisture will condense on the surface, preventing the paint from securing a firm hold. New wood should be painted as soon as possible after erection to prevent cracking and absorption of moisture.
