Scientific American 12, 2.12.1854
In No. 4. Vol. 10, Scientific American, you copy from the London Builder, "woodwork painted in October looks better at the end of four years, than if painted in June it would at the end of two," which is true provided the same preparation of paint is used. In cold weather the oil is thicker and there is more oil in proportion to the quantity of dry paint put on, at a coat. But if the same quantity of oil in proportion to the dry paint is put on in June as in October, the painting will be durable. This can be done by making the paint very thin and putting on more coats, or what is better, boil the oil with one pound of litharge to four gallons of oil, until the latter loses its yellow oily appearance, ths will thicken the oil sufficiently and make tha paint dry well. In every instance paint enough should be put on to have a good gloss, if intended to stand the weather. No turpentine should be used in outside house painting.
