the lumber and reduce the paint according to its absorbing properties. Note general information in regard to priming new work. The paint should be mixed to a thin consistency to fully satisfy the lumber with only enough pigment used to fill the grain of the wood and not leave an excess of pigment on the surface. This will allow the middle coat to penetrate through the priming coat to a sufficient depth to adhere to the fiber of the wood, as well as the pigment in the primer, thereby assisting in binding itself to the surface as well as to the coats that are applied over it.
If the primer is mixed to a heavy consistency, it will retard absorption or penetration and leave an excess of pigment on the surface that will under contraction and expansion break loose when successive paint coats are applied.
Second or Middle Coat. Before applying the second or middle coat, be sure the priming coat is hard dry over the entire surface. As this is the medium between the foundation or priming coat and the protecting or finishing coat, extreme judgment must be used in mixing the paint for this coating. It must not be too elastic and should dry without a high gloss. The paint for this coat, being the easiest working of any applied to the building, requires thorough and careful brushing to assure satisfactory results. Reshellac knots or sappy places if necessary. Knife putty into cracks, seams or nail holes. The paint should be mixed heavy so as to brush out well, also assist in filling and penetrating the priming coat, leaving a surface to which the finishing coat will readily adhere, as well as a surface which properly dries from the bottom out.
Too heavy an oil reduction will leave a high glossy surface over which the finishing coat will not adhere or properly dry. The reduction should be with sufficient turpentine to form penetration and still make a paint which will be elastic enough to withstand contraction and expansion and dry firm. Over such a surface the finishing coat can be
