1. Maximum Moisture Content: 19 percent.

INTERIOR STANDING AND RUNNING TRIM

Interior Softwood Lumber Trim: Finish or 1 Common eastern white, Idaho white, lodgepole, ponderosa, or sugar pine.

Maximum Moisture Content: 19 percent.

Wood Moldings: WMMPA WM 4 made to patterns in WMMPA WM 12 from kiln-dried stock.

Moldings for Painted Finish: P-Grade eastern white, Idaho white, lodgepole, ponderosa, radiata, or sugar pine.

MISCELLANEOUS MATERIALS

Fasteners for Exterior Finish Carpentry: Stainless-steel.

Glue: Aliphatic-resin, polyurethane, or resorcinol wood glue recommended by manufacturer.

INSTALLATION

Condition interior finish carpentry in installation areas for 24 hours before installing.

Prime and backprime lumber for painted finish exposed on the exterior. Cut to length and prime ends.

Install finish carpentry level, plumb, true, and aligned with adjacent materials. Scribe and cut to fit adjoining work. Refinish and seal cuts.

Install to tolerance of 1/8 inch in 96 inches (3 mm in 2438 mm) for level and plumb. Install adjoining exterior finish carpentry with 1/32-inch (0.8-mm) maximum offset for flush installation and 1/16-inch (1.5-mm) maximum offset for reveal installation.

Install standing and running trim with minimum number of joints practical, using full-length pieces from maximum lengths of lumber available. Do not use pieces less than 24 inches (610 mm) long except where necessary. Stagger joints in adjacent and related trim. Cope at returns and inside corners and miter at outside corners.

Nail siding at each stud. Do not allow nails to penetrate more than one thickness of siding, unless otherwise recommended by siding manufacturer. Seal joints at inside and outside corners and at trim locations.
