��well painted. By so doing, the value of a property increases at least 25%. If wooden structures are left bare and ex- posed, the surfaces become roughened and the wood is subjected to warping and cracking. When dampness enters such exposed wood, conditions become favorable for the action of destructive fungi and rotting may take place. Ap- plication of good paint, however, will preserve wood almost indefinitely. Strik- ing illustrations of the truth of this state- ment are afTorded by the condition of those well painted, century-old dwellings to be found throughout the original colonies of this country. Moreover, paints not only decorate and preser\'e wood, but they make it more resistant to fire. For this reason, the application of paints to shingled roofs is often ad- visable. For instance, prepared paints

��contain 60% to 70% of non-combusti- ble, metallic or mineral pigments. When such paints are applied to shingles a very waterproof, semi-metallic film re- sults. The film smooths the rough, fuzzy surface of the wood and prevents warping at the edges, thus doing away with the formation of pockets in which hot cinders, blown from a passing loco- motive or carried from a neighboring fire, might lodge.

Paints for Various Surfaces

Painting the exterior or interior walls of a dwelling constitutes only a part of the many uses for paint. Painting metals of various kinds, varnishing and staining woodwork, and many other ap- plications call for the use of an immense variety of paints and finishes. A list of many of these is shown in the chart.
