CFI Wood & Hardwood Flooring Flashcards

What sheen level is most commonly specified for high-traffic hardwood floor finishes in commercial US installations?

Answer: Satin or low sheen

Satin or low-sheen finishes are preferred in commercial high-traffic areas because they hide scratches and scuffs better than high-gloss finishes.

When staggering hardwood flooring end joints, what is the minimum recommended offset between joints in adjacent rows?

Answer: 6 inches

End joints in adjacent rows should be offset by a minimum of 6 inches to avoid a stair-step or H-pattern that weakens the floor structure.

Which direction should hardwood flooring boards typically run in a rectangular room?

Answer: Parallel to the longest wall or dominant light source

Running boards parallel to the longest wall or the primary light source (windows) elongates the room visually and is the standard installation practice.

What tool is used to measure the moisture content of wood flooring planks and subfloor materials on-site?

Answer: Moisture meter

A moisture meter—either pin-type or pinless—measures the percentage of water content in wood flooring and subfloor materials before and during installation.

What is the primary purpose of 'back-rolling' adhesive before installing glue-down hardwood?

Answer: To ensure uniform coverage and collapse air pockets in the adhesive bed

Back-rolling the adhesive with a roller after troweling ensures full, uniform coverage and eliminates voids or ridges that could cause hollow spots under the planks.

Prefinished hardwood flooring is factory-finished with aluminum oxide, which provides what key advantage over site-finished floors?

Answer: A harder, more scratch-resistant surface due to UV-cured aluminum oxide coatings

Factory-applied aluminum oxide finishes are UV-cured under controlled conditions, creating an extremely hard, scratch-resistant surface superior to most site-applied finishes.
