1. Composition
Wood flooring can be made from solid wood or from wood veneers,
glued together. It is available both with and without a finish.
Unfinished flooring refers to a product that is first installed
at the site without any finish. After installation, it must then
be sanded and finished. Pre-finished flooring is sanded and finished
at the factory. It only requires installation to be ready for use.
Solid wood flooring is made of solid lumber. It is available both
unfinished and pre-finished. Solid wood flooring comes in several
forms and sizes, including:
• STRIP - solid boards with thicknesses of 1/2" or
3/4" and widths of 1½", 2" or 2¼".
•
PLANK - solid boards with thicknesses of 1/2" or 3/4" and
widths of 3" to 8".
•
PARQUET - patterns made from individual wood pieces
Engineered wood flooring is made by bonding thin layers of lumber
with an attractive veneer finish. It also is available unfinished
and pre-finished. Engineered wood flooring comes in the following
forms and sizes:
• STRIP - engineered boards with thicknesses of 5/16",
3/8", 1/2" or 5/8" and widths of 2" or 2¼".
•
PLANK - engineered boards with thicknesses of 5/16", 3/8",
1/2" or 5/8" and widths of 3" to 8".
•
PARQUET - engineered wood tile patterns available in sizes of 9" x
9", 8" x 8" and other sizes.
Solid wood flooring vs. Engineered Wood Flooring:
Most solid wood strip or plank can only be installed with nails
over a wood subfloor. Solid wood parquet and short length strip
or plank can be installed with an adhesive on a variety of non-wood
subfloors. Solid wood flooring is very susceptible to moisture
and can not be used below grade, in areas such as basements,
or in high-humidity environments.
Engineered flooring can be installed with adhesive on a variety
of subfloors. Some engineered strip and plank can be installed
with nails over wood subfloors. And some engineered flooring can
be installed as a "floating" floor without fastening
to the subfloor, by using a bonded tongue and groove technique(used
to install over an existing vinyl floor). Engineered flooring is
much less susceptible to the effects of moisture, and can be used
below grade or in humid climates.
Acrylic impregnated wood flooring is a highly durable pre-finished
product. A high-pressure process is used to saturate the wood with
color pigment and acrylic resin. The result is an extremely hard
finish that is very resistant to abrasion and moisture. Acrylic
impregnated flooring is typically used in commercial applications,
but it is also available for residential purposes. It comes in
the same forms and styles as engineered flooring.

2. Species

3. Appearance & Grades
Appearance of the wood flooring determines its grade. All grades
are equally strong and serviceable.Oak and ash have four basic
grades. Beech, Birch and Hard Maple have three basic grades. They
are::
| OAK GRADES |
| GRADE |
APPEARANCE |
DESCRIPTION |
| CLEAR |
Best |
Best grade, with the best appearance
and most uniform color. |
| SELECT |
Good |
Limited character marks and unlimited
sound sap. |
| NO. 1 COMMON |
Variegated |
Light and dark colors. Knots,
flags, worm holes, and other character marks. Other imperfections must be
filled and finished. |
| NO. 2 COMMON |
Rustic |
A serviceable, economical floor
after knots, worm holes, checks and other imperfections are filled and finished.
Red and white oak species
may be mixed. |

4. Properties
Hardness is a property of wood flooring that relates to its durability.
Harder wood species are more durable and more resistant to wear.
Dimensional Stability refers to a measure of how much wood expands
or contracts with changes in temperature and humidity. The chart
below lists hardness and dimensional stability for various wood
species.

5. Cuts
| Several methods are used to cut raw wood logs into
boards for flooring. Plain Sawing is the most
common method. Because it makes the best use of the raw wood, plain sawing
is the most cost-efficient method. However, variations and growth ring
patterns are more noticeable. |
 |
| Quarter Sawing and
Rift Sawing cut the boards from the log in a different
manner than plain sawing. These methods are more expensive because
they waste more of the raw log. However, boards produce by these
methods can be more dimensionally stable and can wear more evenly. |
 |
| The Rotary Cut method
is used to shear thin layers from the perimeter of raw logs. Most engineered
wood floors are cut in this manner. |

6. Finishes
Lasting beauty requires minimal care with today's wood floor finishes.
The right finish protects wood flooring from wear, dirt and moisture
while giving the wood an attractive color and sheen. Today most
wood floors are finished with a stain and a top coat. Technology
has provided a wide selection of wood flooring finishes, each with
its own distinct benefits and appearances.
Surface Finishes
Surface finishes are very popular today because they are durable,
water-resistant and require minimal maintenance. Surface finishes
are blends of synthetic resins. These finishes most often referred
to as urethanes or polyurethanes remain on the surface of the wood
and form a protective coating. They are generally available in
high-gloss, semi-gloss, satin and matte. Any one of the surface
finishes are appropriate for the kitchen.
There are basically four types of surface finishes:
Oil-modified urethane is generally the most common surface finish
and is easy to apply. It is a solvent-base polyurethane that dries
in about 48 hours per coat. This type of finish ambers with age.
Moisture-cure urethane is a solvent-base polyurethane that is
more durable and more moisture resistant than other surface finishes.
Moisture-cure urethane comes in non-yellowing and in ambering types
and is generally available in satin or gloss. These finishes are
extremely difficult to apply, have a strong odor and are best left
to the professional. Drying time is about 20 hours per coat.
Swedish finish or acid cure urethane is a clear and fast drying
finish. It is durable and non-yellowing. However, this type of
finish usually dries too quickly for use in South Florida. It also
has an extremely strong odor and should be applied by a highly
skilled wood flooring professional.
Water-based urethane is a waterborne urethane that dries by water
evaporation. These finishes are clear and non-yellowing. They have
a milder odor than oil-modified finishes have and they dry in about
two to three hours. Foot traffic should be held off for 48 hours.
Water-based urethanes are generally more expensive.
Penetrating Stain and Wax
Penetrating stains are used to alter the natural color of wood
materials to suit the homeowner's taste. Colors can range from
dark brown to off white, with the wood being stained and the finish
used contributing to the final color. It is always wise to request
a sample of what you select before the work is even started.
Paste wax finishes are not as common as they once were, but in
certain instances the "patina" appearance will best suit
the decor. They require more maintenance than urethane finishes;
and new wax needs to be applied to the floors periodically as determined
by use.
