Question 1

What is a 'T-molding' transition strip designed to connect?

Accepted Answer

Two floor surfaces at the same height separated by an expansion gap

Answer

A T-molding bridges an expansion gap between two same-height floor surfaces, allowing independent movement of each side.

Question 2

When installing hardwood flooring with a face-nail at the wall, what is the recommended fastener used to prevent the wood from splitting?

Accepted Answer

Pre-drill and use a finish nail

Answer

Pre-drilling a pilot hole before driving a finish nail prevents the hardwood from splitting and allows the nail to be set below the surface and filled.

Question 3

What is the correct method for installing a carpet transition at a doorway where carpet meets hard-surface flooring?

Accepted Answer

Tack strip at the edge with a metal Z-bar or Gripper bar securing the carpet edge

Answer

A Z-bar or Gripper bar captures the carpet edge at the transition, holding it flat and providing a clean, durable seam between carpet and hard-surface flooring.

Question 4

Which solvent-based adhesive type is commonly used for installing sheet vinyl (resilient) in commercial applications and requires adequate ventilation?

Accepted Answer

Cutback adhesive or pressure-sensitive contact adhesive

Answer

Cutback and contact adhesives used for commercial sheet vinyl installations contain VOCs requiring adequate ventilation and respiratory protection.

Question 5

What is 'transfer' in the context of testing pressure-sensitive adhesive for LVT installation?

Accepted Answer

Adhesive that strings or peels off the substrate onto the flooring back when pulled

Answer

Transfer means the adhesive is properly grabbing when the flooring back shows adhesive contact after the tile is pressed and pulled back.
