CFI CFI Tools & Equipment 1 — Questions and Answers
Question 1: What is the primary function of a pneumatic flooring stapler (cleat nailer) in hardwood installation?
- Cutting planks to length at precise angles
- Blind-fastening hardwood planks through the tongue to the subfloor (Correct answer)
- Applying adhesive beads along plank edges
- Scoring vinyl planks before snapping
Correct answer: Blind-fastening hardwood planks through the tongue to the subfloor
A pneumatic cleat nailer drives cleats or staples through the tongue of hardwood planks at an angle, securing them to the subfloor while keeping fasteners hidden.
Question 2: Which type of saw is best suited for making precise miter and bevel cuts in hardwood flooring transition pieces and moldings?
- Reciprocating saw
- Table saw
- Compound miter saw (Correct answer)
- Oscillating multi-tool
Correct answer: Compound miter saw
A compound miter saw makes accurate miter (left/right angle) and bevel (tilted) cuts in one pass, making it ideal for cutting moldings and transition strips.
Question 3: A tapping block and rubber mallet are used during flooring installation to:
- Drive nails through the face of planks
- Gently seat tongue-and-groove planks together without damaging the edges (Correct answer)
- Score and snap vinyl tile
- Flatten high spots in the subfloor
Correct answer: Gently seat tongue-and-groove planks together without damaging the edges
A tapping block protects the plank's edge while the rubber mallet drives planks snugly together, ensuring tight joints without chipping or crushing the tongue or groove.
Question 4: What is the purpose of a floor scraper or floor stripper machine in a flooring project?
- Applying new adhesive evenly before installation
- Removing old adhesive, tile, or floor coverings from the subfloor (Correct answer)
- Grinding high spots down to level the subfloor
- Buffing the finished floor after installation
Correct answer: Removing old adhesive, tile, or floor coverings from the subfloor
A floor scraper or ride-on stripper machine is designed to remove existing floor coverings and adhesive residue efficiently from the subfloor prior to new installation.
Question 5: Which tool is used to check whether a subfloor is flat (within 3/16 inch over 10 feet) before flooring installation?
- Moisture meter
- Chalk line
- Long straightedge or 10-foot floor-flatness gauge (Correct answer)
- Spirit level (torpedo level)
Correct answer: Long straightedge or 10-foot floor-flatness gauge
A 10-foot straightedge is used to span the subfloor and identify high or low spots that exceed the 3/16-inch flatness tolerance required by most flooring manufacturers.
Question 6: A notched trowel's primary purpose in flooring installation is to:
- Apply grout between tile joints
- Spread adhesive at a controlled, uniform thickness over the subfloor (Correct answer)
- Score resilient sheet flooring before cutting
- Mix self-leveling compound before pouring
Correct answer: Spread adhesive at a controlled, uniform thickness over the subfloor
A notched trowel spreads adhesive into uniform ridges, ensuring consistent coverage thickness and proper bonding area for flooring materials.
