WLFI Repair Techniques & Restoration 3

Question 1

A wood floor inspector observes squeaking in a glue-down engineered floor over a concrete slab. What is the most likely cause?

Accepted Answer

Adhesive bond failure causing planks to move against each other

Answer

When adhesive loses its bond, planks shift slightly under foot traffic, causing boards to rub and produce squeaking sounds.

Question 2

What is the best method to repair a scratch that penetrates only the finish layer of a hardwood floor without reaching the wood?

Accepted Answer

Lightly buff the area and apply a compatible floor finish touch-up product

Answer

Surface-only scratches can be repaired by buffing and applying a compatible finish touch-up without full refinishing.

Question 3

During an inspection, a laminate floor plank shows white haze (clouding) within the wear layer. What is the most appropriate corrective action?

Accepted Answer

Replace the affected plank(s), as the wear layer damage is permanent

Answer

Clouding within a laminate's wear layer is structural damage that cannot be buffed or polished out; plank replacement is required.

Question 4

Which repair technique is recommended for fixing a loose solid hardwood floor nail-down plank near a wall?

Accepted Answer

Face-nail with finish nails near the wall edge and fill nail holes

Answer

Near walls where blind-nailing is impractical, face-nailing with finish nails and filling the holes is the accepted repair method.

Question 5

An inspector finds cupping (edges higher than center) in a solid hardwood floor. After moisture levels have been corrected and equalized, what is the next step?

Accepted Answer

Wait for the floor to flatten naturally before deciding if sanding is needed

Answer

Cupped floors often flatten on their own once moisture equilibrium is restored; sanding too early can result in a crowned floor when the wood dries.
