The outside of a house, garage, or any other exposed woodwork, is painted mainly to protect the wood from the weather. Protection is the first consideration and should be kept in mind when selecting the paint, preparing the surface, and applying the paint. A poor quality paint will not give the necessary protection, no matter how carefully applied, and good paint will be equally unsatisfactory if carelessly or improperly applied. An outside surface not adequately covered will soon rot and be attacked by insects. A good paint job with good materials will pay for itself by preserving the wood for many years. The homeowner will often select spring as the time of year best suited for outside painting. This does not happen to be the best time of year from a standpoint of good painting, because the wood has been exposed to the snow and ice of winter and is generally damp on the inside. While it is all very well to have the house freshly painted for the summer, the prime consideration must be to put a good, lasting coat of paint on the wood. The best time for outside painting is in the summer or early fall when the wood surfaces are dry and the temperature is neither too low nor subject to violent changes. Painting, as previously mentioned, should not be done when the weather is damp.
AmountThe amount of paint needed for one coat will depend upon the wood to be covered and the extent of the painter's plans. Another point to be considered is whether the coat is the first or the finish coat. One gallon of paint for every 500 square feet is an approximate figure to use in determining the amount for a particular job.
