  1. When performing a moisture test on a concrete slab before resilient flooring installation, what is the maximum acceptable moisture vapor emission rate (MVER)?

    Answer: 5 lbs/1000 sq ft/24 hrs

    The industry standard maximum MVER for most resilient flooring installations is 5 lbs per 1000 sq ft per 24 hours using the calcium chloride test.

  2. A newly installed hardwood floor shows cupping two weeks after installation. What is the most likely cause?

    Answer: Excessive moisture from below or high humidity

    Cupping in hardwood floors is caused by the bottom of the board absorbing more moisture than the top, causing the edges to rise.

  3. Which instrument is used to measure the flatness of a subfloor before installation?

    Answer: Straightedge and wedge gauge

    A straightedge (typically 10 feet) combined with a wedge gauge is the standard method to measure subfloor flatness and identify high or low spots.

  4. What is the standard subfloor flatness tolerance for most resilient and ceramic tile installations?

    Answer: 1/8 inch in 10 feet

    Most resilient and ceramic tile manufacturers require no more than 3/16 inch variation in 10 feet, but the tighter standard is 1/8 inch in 10 feet for many products.

  5. During a quality inspection of a carpet installation, you notice peaked seams. What is the most likely cause?

    Answer: Over-stretching the carpet

    Peaked seams are caused by over-stretching the carpet, which forces the seam edges upward and creates a ridge.

  6. What cleaning method is recommended for routine maintenance of unfinished hardwood floors?

    Answer: Dry dust mopping or vacuuming

    Unfinished hardwood floors should only be dry dust mopped or vacuumed, as any moisture can cause damage, staining, or warping.

  7. A client reports that their LVP (luxury vinyl plank) floor is experiencing edge lifting at the walls. What installation error most likely caused this?

    Answer: Insufficient expansion gap left at walls

    LVP expands and contracts with temperature changes; if an insufficient expansion gap is left at walls, the floor has no room to expand and edges will lift.
