4-9/16" Primed Flatstock Lumber – Pine, Finger Jointed, Primed

4-9/16" primed finger-jointed pine flatstock is a smooth, factory-primed board for interior trim, shelving, and millwork applications, available at Windsor Plywood. Finger-jointing joins shorter lengths of pine end-to-end into longer, dimensionally stable boards. The factory-applied primer seals the wood and provides an even base for finish painting on site.

Specifications

Common Uses

4-9/16" primed pine flatstock is used for interior window stools, apron trim, shelf boards in painted built-ins, wainscoting cap rails, and horizontal trim elements in interior millwork. It is also used as a substrate for painted panelling and as a base for built-up casing assemblies.

Pro Tips

• Prime the cut ends on site before installation -- the factory primer does not cover fresh-cut ends, and bare end grain absorbs finish paint unevenly.
• Fill nail holes and any imperfections with a lightweight spackling compound before applying finish paint for a smooth, professional result.
• When using as a shelf board, support at no more than 24" intervals to prevent sagging under load.

Frequently Asked Questions

How many coats of paint do I need over the factory primer?
Two coats of quality interior latex paint over the factory primer produces a durable, professional finish. Sand lightly with 220-grit between coats for the smoothest result.

Can I use this product for exterior trim?
No. Finger-jointed pine is not recommended for exterior applications -- the joints can fail in exterior moisture conditions. Use solid cedar or engineered exterior trim products for all exterior applications.
