A priming for outdoor woodwork, which is to be painted white, is made by mixing together white lead, 10 oz. red lead, 1 oz.; and driers, loz.; thin with half raw oil and turps. No hard and fast rule can be laid down, however, as some white lead will carry double as much thinners as others, according to the quality and age of the lead and whether it is ground stiff or not. For the following coats put less turps in each time - for the first coat, say, one-third turps, for the second coat, one-sixth turps, and for the third coat, no turps. The paint should be of about the consistency of cream.
