New Work. Be sure the character of the lumber is understood as to its absorption of the paint, and to assure satisfactory results see that the paint is reduced as thin as possible according to the conditions. Do not paint immediately after rain storms, heavy dews, fogs or in frosty weather. See that the surface to be painted is thoroughly dry and in proper condition to receive paint.

Do not follow too closely after the carpenter, as siding which has been tied in bundles is very often wet on the inside. Allow time for the siding to dry out, remembering that it is very hard to secure dry lumber. Do not apply shellac too heavy to knots and sappy places. Have it thin and brush well into the knots or other places that require shellac. Where light shades of paint are to be applied, use white or very light colored shellac.

Priming. It is bad practice to prime a building from a carpenter's scaffold. It is best to have the entire building ready to prime at one time so that the same mix of paint can he used. In this way a more even and better coat of priming can be given.

When a building or any part of it is ready to receive the priming coat, the carpenter should remove all scaffolds, blocks and braces. This leaves the building with no part of the surface hidden and all of it can be primed without interference. Ridges are left on a building primed with blocks or braces nailed to the corner strips or any part; when touched up, it is impossible to hide these spots so they will not soon show through the second and third coats.

It is good policy to always prime a building before the plasterer commences his work, as the priming coat will keep the dampness and fumes of the mortar beds from
