Finishing Exterior Plywood

Field observations, exposure fence studies, and Weathermeter tests all indicate that the best paint system for Exterior plywood siding or for any plywood exposed to weather, is the same as for ordinary wood siding.

The high-grade exterior house paints of either TLZ (titaniumJead-zinc) formulations or straight white lead and oil give excellent service on plywood. IJse-records indicate the TLZ paints tend to have more lasting appearance qualities, although the white lead and oil paints give equal protection and after weathering usually provide a superior surface for repainting.

During construction, all edges of plywood should be sealed with a heavy application of a high-grade exterior house primer, aluminum paint, or heavy lead and oil paint. (FHA recommendations for paint for sealing edges are: 100 pounds white lead paste, ltl gallons raw linseed oil and 1 pint dryer, mixed and applied without thinning.) This applies alike to exposed edges (if any) and edges of panels that are lapped or butted even if to be covered with moldings.

The initial or prime coat is the most important. 'fhis should be applied as soon as possible after erection. It should be b:ushed on thoroughly. Subsequent coats may be brrrshed on or sprayed; they should follow as closely as conditions permit.

In unusually damp locations, or where unusual humidity conditions are to be experienced, the plywood panels should be back-primed during construction.

Basic Three-Coat

System for Exterior Painting

1. The initial or pri'me coat. This is most important coat. Use a high-grade exterior primer thinned with at least one pint of pure raw linseed oil per gallon of paint; apply with brush; Or use a high-grade exterior aluminum house paint, or an aluminum primer compounded from lfi to 2 pounds aluminum paste or powder in one gallon of long oil spar varnish, mixed just prior to application to obtain optimum leafing characteristics. Greater opacity of the finish coats or an additional coat, especially if white, may be required to completely mask an aluminum primer.)

Other Finishes

Textured or stucco-type finishes are feasible by application of materials specially designed to obtain these efiects. Synthetic resin or oil-base paints containing mineral particles, asbestos fiber, etc., as part of the pigment have proved popular and in most cases quite satisfactory. Follow manufacturer's recommendations; remember importance of initial or prime coat.

The Douglas Fir Plywood Association, Tacoma 2, Wash., has printed suggested finishing procedures fbr interior plywood paneling and exterior siding. Single copies or small quantities are available free of charge.

Milpak Grade Rules Ready For NHLA Committee

Washington, June 15-At a conference held June 1 in the Chicago headquarters of the National Hardwood Lumber Association, Chief Inspector William H. Nelson of N.H.L.A. and J. L. Stearns of the Timber Engineering Company completed the final draft of a proposed grade rule for Milpak, the new convenient packaged hardwood lumber developed from low grade material. This will be presented to the NHLA Inspection Rules Committee which meets in Chicago June 29 and 30.

The new grade rules define the minimum cutting sizes, required average size of Milpak pieces and minimum quality standards with respect to number, size, and type of defects permissible. It covers both kiln dried and air dried stock as well as bundling requirements.

John W. McClure, secretary-manager of the National Hardwood Lumber Association and others on his staff predicted that Milpak will find markets in which hardwood lumber has not previously entered as extensively as it should.

The Research Laboratory of the Timber Engineering Company has been engaged by the National Lumber Manufacturers Association Hardwood Research Committee {or the past two years on the Milpak project. A 5 day training course on Milpak and the utilization of low grade hardwoods is being conducted at the Washington, D. C. Laboratory. Reservations are now being taken for the third course scheduled for week of August 21.

For further information on Milpak, or low grade hardwood utilization write C. A. Rishell, Director of Research, Timber Enginering Company, Washington 6. D. C.

Appointed Wholescle Distributor For Vertigrrqin Door

2 and 3. Over the primer apply the second and according to the manufacturer's directions.i

Iwo-Coat System coats, For weatherability co-mparable to a three-coat system described above, an equal dry film thickness is necessary. l. High grade exterior primer thinned with at least one pint of pure raw linseed oil per gallon of paint; apply with brush.

Haley Bros., wholesale distributors of windows, doors, plywood, and moulding, are distributors of the widely known Nicolai Vertigrain hollow. core flush doors.

A feature of the core design of the Vertigrain door is that at each of the intersections of the members making up the grid there are vents permitting the free flow of air from one cell to another, and through a groove in each stile, to the outer air. This allows equalization of temperature and humidity of the air within the door with that of the room.
