EXTERIOR PAINTING

protected, like under porches and verandas, and portions shielded by trees and other buildings, which would render them in about the same condition as under verandas, should receive a coat of paint mixed so as to penetrate the old surface and dry hard and firm without high gloss. If one mix of paint, which will satisfy the exposed portion of the building, is applied over the entire surface and to the protected or hard parts of the building, this oily or elastic coat of paint will dry with a full or heavy gloss, retarding the drying of the second or finishing coat, also causing blistering, checking, cracking and flatting in a short time.

First Coat. For an exposed or weather-beaten surface, the paint should be mixed with 2-3 oil and 1-3 turpentine to assist in penetrating the old surface, as well as parts on which some paint still remains. It should be applied with a full brush to fully satisfy the surface and be well and evenly brushed out so as not to have an excess of paint on the surface where the old paint remains.

The cornices and protected portions should receive paint that is mixed half flat or with enough turpentine to force penetration through the old paint, thus firmly binding this coat to the surface and preventing the second or finishing coat from crawling. The paint should be applied smoothly and evenly and be well brushed in. Do not flow the paint on and expect a uniform coat.

Second Coat. When the surface is thoroughly hard, putty all cracks, seams and nail holes, knifing the putty well in. One mix of paint for finishing coat can be applied over the entire surface. This will dry uniformly. The paint should be mixed to medium heavy and elastic consistency and be well and evenly brushed out.

Cracked and Peeled Paint. Owing to the many kinds of cracked and peeled surfaces, as well as the innumerable causes from which they come, it is impossible to give definite directions for repainting under all of the varied
