CFI CFI Tools & Equipment Operations 1 — Questions and Answers
Question 1: What is the primary purpose of a floor roller in resilient and LVP flooring installations?
- To flatten subfloor high spots
- To apply even pressure ensuring full adhesive transfer and bond (Correct answer)
- To score sheet goods for cutting
- To spread adhesive evenly
Correct answer: To apply even pressure ensuring full adhesive transfer and bond
A 100-pound floor roller is rolled across newly installed resilient flooring to ensure complete contact between the flooring and adhesive for a full bond.
Question 2: A pneumatic flooring cleat nailer is specifically designed to blind-nail at what angle through the hardwood tongue?
- 90 degrees (straight down)
- 45–50 degrees (Correct answer)
- 15–20 degrees
- 70–75 degrees
Correct answer: 45–50 degrees
Pneumatic cleat nailers drive fasteners at a 45–50-degree angle through the tongue so the nail head is hidden when the groove of the next board is engaged.
Question 3: Which tool is used to measure the flatness of a subfloor to identify high and low spots before flooring installation?
- Tape measure
- Moisture meter
- 6-foot or 10-foot straightedge (Correct answer)
- Chalk line
Correct answer: 6-foot or 10-foot straightedge
A 6-foot or 10-foot straightedge is placed across the subfloor in multiple directions to identify deviations exceeding the manufacturer's tolerance.
Question 4: What type of saw is best suited for making precise crosscuts on hardwood flooring planks during installation?
- Circular saw
- Jigsaw
- Miter saw (chop saw) (Correct answer)
- Oscillating multi-tool
Correct answer: Miter saw (chop saw)
A miter saw produces clean, accurate crosscuts quickly and is the standard tool for cutting hardwood planks to length during installation.
Question 5: A pin-type moisture meter measures wood moisture content by:
- Weighing a sample before and after drying
- Passing electrical current between two probes inserted into the material (Correct answer)
- Infrared scanning of the surface
- Measuring humidity in the air above the surface
Correct answer: Passing electrical current between two probes inserted into the material
Pin-type meters measure the electrical resistance between two probes driven into the wood; resistance decreases as moisture content increases.
Question 6: When using a knee kicker during carpet installation, the installer should strike it with:
- The heel of the hand
- The knee cap in a quick forward thrust (Correct answer)
- A rubber mallet
- The toe of the boot
Correct answer: The knee cap in a quick forward thrust
The installer uses the knee cap to deliver a quick, firm forward thrust to the padded end of the knee kicker, stretching the carpet onto the tack strip.
