White Lead for Many Purposes Gives Lasting Service LEVEN years ago, in the E middle of a cold winter, the exterior of the Methodist Episco pal Church of Greenwich, Conn., was painted with pure white lead Inside and Out, on Wood and Metal, White head Paint Performs Remarkably of this white lead interior is more remarkable when it is considered that it is in a school, where wear and tear on painted walls is gen erally great. paint and has not been repainted since. It is a wood building erected in 1868 and dedicated the following In Stamford, Conn., just a few miles from Green wich, a new post office was erected in 1915. It is a year. That it has not been painted in eleven years, despite the extremely adverse conditions when last painted, is a strong testimonial to the quality of both brick building with a wooden cornice which is dec orated with bright colors and gilt on a background of light colored paint. Pure white lead paint was workmanship and materials. So far as can be de termined, this building has always been painted with white lead, which probably partly accounts for the excellent performance of the last job, for the old white lead already on the wood offered a firm foun dation for the new paint. Another Greenwich building wherein pure white lead paint has given an excellent account of itself, but for an entirely different purpose, is the Have- meyer School. Seventeen years ago the entire interior was painted with pure white lead, mostly flat finish. It was not repainted until two years ago. This demonstrates the economy of using the best paint for interiors, for white lead can be repeatedly washed and its good appearance maintained for years, COUITESY CUXMWICB FUSS Havemeyer School, Greenwich, Conn., in which fiat white lead paint did not require repainting for fifteen years. whereas cheap flat paint washes off and can not be washed clean, for dirt imbeds in its surface and the paint becomes streaky. The fifteen years of service used for this work, also, when the building was built. A visual inspection made in August, 1934, nineteen years after painting, showed the paint was in such good shape as to give the impression of com paratively recent repainting, yet no repainting has been done since the original paint was applied. White lead was put to still another use on the Greenwich Trust Co. building, where it has again proven both its versatility and durability. Metal sash was the only exterior work requiring paint. It was painted with pure white lead for all coats in 1926 and has not been repainted in the eight ensuing years. Wood sash and trim in the Greenwich Y.M.C.A. was also painted with pure white lead, in 1929, and is not yet in need of repainting. Examples of the excellent serviceability of pure white lead paint might be continued almost indefi nitely, but those cited demonstrate the variety of application to which white lead can be put and the great durability of this premier paint pigment no matter what the use. Climate in Connecticut is far from easy on paint, for temperature variations are wide, winters severe. Near the sea. salt air adds to the hardship of paint. rtfCUSKERS PHOTO SERVICE Methodist Episcopal Church, Greenwich, Conn., last painted eleven years ago with pure white lead paint.

White lead has endured on the wood cornice without repainting for nineteen years. STUDY of the prevention of decay favoring A conditions in wood sash, conducted bv Mr. Albert Hermann, Research Engineer of the Western Pine Association, Portland, Oregon, has revealed that moisture absorption through joints is the prin cipal cause of trouble, and that heavy white lead paint applied to the joints is the most effective of the methods tested for preventing this undesirable absorption. firm which has long relied upon pure white lead paint for the bulk of its painting and decorating. The Company is now being operated by its second and third generation of Newtons and has always been known for the high quality of its work. It seems to go almost without saying that those painters and decorators who are able to continue in business year after year are those who adhere to the old sound policy of giving only good workmanship and good materials for their customers' money. The method of testing was to construct sash cor ners all uniformly painted so that differences in moisture absorption would be indicative of moisture absorption differences through the joint only. These sash corners, after various treatments as indicated in the accompanying table, were stood upright in 3/16 in. of water. A saw kerf 1/32 in. deep was cut into the bottom of each joint to break the paint covering at this point. These kerfs provided the only access of moisture to the joints when immersed in the water. Results are tabulated to show the number of days required for the test specimens to pick up 10 per cent in moisture content, the initial moisture content of all specimens being approximately 12 per cent and the final value 22 per cent. rminm< ph o t o mvici The wood trim of the Greenwich, Conn., Y.M.C.A., shown here, was last painted in 1929 with pure white lead.

These results indicate the marked superiority of white lead for the purpose. The white lead paint used was a pure white lead paste thinned with raw linseed oil to a consistency of rich cream. A small amount of Japan drier was added. All joint surfaces were heavily coated, and the joints assembled at once so that excess lead was squeezed out but all voids in the joints filled. [3] LIA25290
