Plank. Wood flooring boards 3” and wider designed to be installed in parallel rows. In random width plank, the boards vary in width from 3” to 8”.

Plain Sawn. The usual way of cutting a log. It gives a random mix of grain patterns.

Prefinished. Factory-finished flooring that requires only installation. (Also see “Job Finished”.)

Quartersawn. Wood which has a grain that runs parallel to the length of the board. (It is sometimes called “vertical grain”.) In oak the boards have ray-like markings running diagonally across them.

Reducer. A strip of wood used to join two floors of different heights.

Refinishing. Sanding about 1/32” – 1/16” off the surface of a wood floor and then applying new finish in order to revitalize the look of a floor. Color can be changed in this process.

Tongue and Groove. In strip, plank and parquet flooring, a tongue is cut on one edge and a groove cut on the opposite edge. As the flooring is installed, the tongue of each strip or unit is interlocked with the groove of the adjacent strip or unit.

Trim. The finish moldings, such as baseboards or base shoe.

Vapor Retarder. A material, such as foil, plastic film or specially coated paper, with a high resistance to vapor movement, used to control condensation or prevent migration of moisture.

 

TYPES OF FINISHES

Polyurethane finishes are most commonly used today because of their durability and easy care. They are all generally available in high-gloss, semi-gloss and satin.

An oil-based polyurethane finish imparts a slight honey colored tint to the wood. This finish ambers over time, which may not be desired on light woods. When applied, it usually takes 8-10 hours per coat to dry and has a strong odor.

A water base urethane is clear and looks very natural on wood. Some types are more durable than oil-based. It generally takes 3-4 hours per coat to dry. This finish has little odor when applied.

Wax is often used to create a soft, aged luster. Though you may renew the finish yourself, wax water spots easily, requires maintenance and is slippery. Wax is amber in color and has a low sheen. It has a mild odor when applied.

Tung oil is a penetrating finish which gives a soft hand rubbed look when applied in multiple coats, slightly ambering the wood. It requires drying overnight between coats and has a mild odor when applied. Tung oil is higher maintenance than urethane, requiring periodic buffing and reapplication.
