Acrylic Impregnated or Acrylic Infused
A generic term for wood-plastic composite flooring often used in commercial properties, acrylic impregnated wood is made by infusing wood with acrylic resin, so the color and finish are not only consistent on the surface, but throughout the wood as well. Although durable, acrylic impregnated wood floors cannot be refinished and are susceptible to water staining.
A substance that bonds the finished floor product to the substrate (the layer that underlies the floor product).
Refers to wood dried by exposure to air (such as in a yard or shed) without artificial heat, as is used in kiln drying.

Asphalt Saturated Felt Paper
Asphalt-saturated products are used as vapor retarders and typically come in rolls installed over the subfloor with the seams overlapping a minimum of 4 inches. Also referred to as #15 or #30 felt, asphalt saturated felt paper meets industry standard ASTM D4869.
The American Society for Testing and Materials develops and publishes voluntary technical standards for a wide range of materials, products, systems, and services. Although ASTM International standards are not required or enforced, they have been adopted by rules-making industry and governmental bodies.
ASTM (modified) D-4944-043
Also known as the Calcium Carbide (CM) Test where a mid-depth sample of the screed is taken and allowed to react with calcium carbide reagent. Upon reacting, the mixture releases acetylene gas, the amount of which indicates the level of moisture in the sample.
The American Society for Testing and Materials (ASTM) developed this standard test for determining the rate of moisture vapor emission from the surface of a concrete floor using anhydrous calcium chloride. All concrete subfloors emit some amount of moisture in vapor form, and all floor coverings are susceptible to failure from excessive moisture vapor emissions. The calcium chloride moisture test results are used to determine whether the floor is acceptable to receive resilient floor covering. The calcium chloride moisture test is the industry standard for making this determination and is a practical, well-established and accepted test of dynamic moisture.
The American Society for Testing and Materials (ASTM) developed this standard test for determining relative humidity in concrete floor slabs using in situ probes (moisture testing sensors inside the slab itself). In-situ probes measure relative humidity (RH), providing a composite picture of overall slab moisture levels. Excessive moisture permeating from floor slabs after installation can cause floor covering delamination, peeling, blistering, staining and sweating.

Chatter Marks or Chatter
A rippling pattern of half-circle marks that appear on hardwood floor surfaces as a result of improper sanding.
A crack that occurs on the ends and surfaces of lumber during drying. Checking is caused by shrinkage differences between the surface and core of drying lumber. Since the ends and surfaces dry first, they tend to shrink first, but are restrained by the swollen core. This results in stresses building up near the surfaces which, if they become too great, cause the lumber to check.
Checking of finish of wood flooring appear as small, uniformly spaced cracks in the finish that run parallel with the grain of the wood. Checking is the result of stresses created from shrinking and swelling of the wood, usually caused by exposure to extreme heat or cold, or extremely dry or wet environment.
A barbed fastener commonly used to fasten hardwood flooring.
Visual changes in the color of wood. Most commonly caused by exposure to light, deprivation of light and air, oxidation or other chemical reaction.

Flat Sawn (Plain Sawn)
When lumber is cut from logs, it is typically cut in one of three ways: quarter sawn, rift sawn or flat (plain) sawn, depending on how the log is oriented to the saw. Flat sawn is cut into long planks where the rings run parallel to the board and is the most common and least expensive wood.
Quarter sawn wood (particularly oak) will also often display a pattern of flecks in subtle ribbon-like patterns across the straight grain. This ray pattern has made quarter sawn wood especially desirable for furniture and decorative paneling. See Medullary Rays.
