CFI Transition & Trim Installation 5

Question 1

What is the correct sequence of steps when installing a glue-down transition strip on a wood subfloor?

Accepted Answer

Apply adhesive → press track down → allow cure → snap in cap

Answer

Adhesive is applied first, the track is pressed into position with the correct gap spacing, allowed to cure, and then the decorative cap is snapped in last.

Question 2

When a transition reducer is used on a floating LVP floor, the installer should NOT:

Accepted Answer

Glue or nail the flooring planks to the subfloor beneath the reducer

Answer

Gluing or nailing floating LVP planks near or under a transition restricts the floor's ability to expand and contract, which can cause buckling or gapping.

Question 3

A customer reports that their newly installed stair nosings squeak underfoot. What is the most probable installation error?

Accepted Answer

The nosings were not face-nailed and/or glued adequately to the stair tread

Answer

Stair nosings must be both glued and face-nailed to fully bond to the tread; inadequate fastening allows movement that causes squeaking.

Question 4

When trimming a length of T-molding cap to fit a doorway, the installer should cut it using:

Accepted Answer

A miter saw or fine-tooth hacksaw, depending on the cap material

Answer

Wood or laminate caps are best cut on a miter saw, while aluminum or vinyl caps cut cleanly with a fine-tooth hacksaw or aviation snips.

Question 5

In a large open-plan installation where floating floor runs exceed the manufacturer's maximum continuous run length, transition strips are used to:

Accepted Answer

Create a control joint that allows each section to expand and contract independently

Answer

When floating floors exceed maximum run lengths (often 40 feet), a transition strip divides the floor into independent expansion zones, preventing buckling.
