Vinyl & Resilient Flooring Flashcards

What is the minimum recommended acclimation time for luxury vinyl plank (LVP) before installation in most US climates?

Answer: 48 hours

LVP should acclimate for at least 48 hours in the installation environment to stabilize its dimensions.

When installing sheet vinyl over a wood subfloor with seams, what is the maximum allowable height difference at the seam?

Answer: 1/32 inch

Subfloor seams must be within 1/32 inch (0.8 mm) to prevent telegraphing through resilient flooring.

Which adhesive spread rate issue can cause vinyl tiles to peak or tent after installation?

Answer: Adhesive applied too thick

Excessive adhesive thickness traps solvents and can cause the tile edges to lift or tent as the adhesive off-gasses.

What type of primer is typically required before applying pressure-sensitive adhesive over a highly porous concrete subfloor?

Answer: Latex sealer or primer

A latex sealer or primer reduces porosity so the adhesive bonds uniformly rather than being absorbed into the concrete.

When cutting luxury vinyl plank with a score-and-snap method, on which side of the plank do you score?

Answer: The wear layer (top) side

Scoring the wear layer (top surface) and snapping downward produces a clean, controlled break.

A resilient floor installed over radiant heat should not exceed which maximum surface temperature?

Answer: 85°F (29°C)

Most vinyl and resilient manufacturers specify a maximum subfloor surface temperature of 85°F (29°C) to prevent adhesive failure and dimensional instability.

What is the primary purpose of a transition strip between LVP and carpet?

Answer: To bridge height differences and protect exposed plank edges

Transition strips cover the exposed edge of the LVP, bridge height differences, and create a safe, finished joint between the two floor types.
