WLFI Repair Techniques & Restoration 2

Question 1

When a single plank in a glue-down hardwood floor has cracked, what is the most appropriate repair method?

Accepted Answer

Replace only the damaged plank by cutting it out and gluing in a new one

Answer

Cutting out and replacing the individual damaged plank is the targeted, industry-standard repair for glue-down floors.

Question 2

Which tool is most effective for removing a single tongue-and-groove plank from the middle of a floating laminate floor?

Accepted Answer

Oscillating multi-tool with a plunge-cut blade

Answer

An oscillating multi-tool with a plunge-cut blade allows precise cuts close to adjacent planks without damaging them.

Question 3

A homeowner reports that a section of laminate flooring has swollen edges (peaking) along the seams after a water leak. What is the inspector's primary recommendation?

Accepted Answer

Allow the floor to dry completely; if peaking persists, replace the affected planks

Answer

Laminate core swelling is typically irreversible once the fiber board has expanded; replacement of damaged planks is required if drying does not resolve the issue.

Question 4

What is the correct sequence for patching a gouged area on a solid hardwood floor that will be refinished?

Accepted Answer

Sand to bare wood → apply wood filler → sand flush → refinish

Answer

Sanding to bare wood first ensures the filler bonds properly, and sanding flush after curing creates a level surface for finishing.

Question 5

During a restoration inspection, you observe that a hardwood floor has been drum-sanded unevenly, leaving visible sanding marks across the grain. What remedial step corrects this?

Accepted Answer

Re-sand with the grain using progressively finer grits starting at 36-grit

Answer

Sanding with the grain using progressively finer grits removes cross-grain scratches and levels the surface properly.
