WALMART MAINTENANCE Carpentry and Structural Repairs 5 — Questions and Answers
Question 1: What does the term 'on center' (OC) mean when referring to stud spacing in wall framing?
- The measurement from the outer edge of one stud to the outer edge of the next
- The measurement from the center of one stud to the center of the next (Correct answer)
- The distance between the inner faces of adjacent studs
- The total number of studs per linear foot of wall
Correct answer: The measurement from the center of one stud to the center of the next
On center (OC) spacing is measured from the centerline of one framing member to the centerline of the next.
Question 2: When cutting lumber with a circular saw, which safety practice is MOST important?
- Always cut toward your body for better control
- Ensure the blade guard is functioning and in place (Correct answer)
- Hold the workpiece freehand for flexibility
- Use a dull blade to reduce kickback risk
Correct answer: Ensure the blade guard is functioning and in place
A functioning blade guard is the primary safety device on a circular saw and must always be in place before cutting.
Question 3: A floor transition strip between two different flooring surfaces in a store aisle has come loose. The BEST permanent fix is to:
- Apply construction adhesive to the bottom and press down
- Re-secure using appropriate fasteners through the factory mounting holes (Correct answer)
- Tape it down temporarily with duct tape
- Replace the entire section of flooring
Correct answer: Re-secure using appropriate fasteners through the factory mounting holes
Re-securing through factory mounting holes with proper fasteners restores the strip to its designed installation and prevents future loosening.
Question 4: When shimming a door to make it plumb during reinstallation, shims should be placed:
- Only at the bottom of the door frame
- At hinge locations and at the strike plate location (Correct answer)
- Evenly spaced every 6 inches along the frame
- Only behind the hinge side of the frame
Correct answer: At hinge locations and at the strike plate location
Shims placed at hinge locations and the strike plate provide support exactly where the door exerts force on the frame.
Question 5: Which wood species is most commonly used for interior structural framing in commercial construction due to its strength and availability?
- Cedar
- Douglas fir or Southern yellow pine (Correct answer)
- Balsa
- Redwood
Correct answer: Douglas fir or Southern yellow pine
Douglas fir and Southern yellow pine are the industry-standard structural lumber species due to their strength-to-weight ratio and availability.
Question 6: A maintenance technician needs to locate studs behind a finished wall to mount a heavy sign. The MOST reliable method is to use:
- Knock on the wall and listen for a solid sound
- An electronic stud finder (Correct answer)
- Measure 16 inches from any corner
- Use a strong magnet to find nails
Correct answer: An electronic stud finder
An electronic stud finder reliably detects changes in wall density to accurately identify stud locations.
Question 7: When repairing exterior wood trim that shows paint peeling and cracking, the correct preparation before repainting is to:
- Apply new paint directly over existing peeling paint
- Remove all loose paint, sand smooth, prime bare wood, then repaint (Correct answer)
- Apply a thick coat of paint to seal the cracks
- Power wash only, then repaint immediately while wet
Correct answer: Remove all loose paint, sand smooth, prime bare wood, then repaint
Removing loose paint, sanding, and priming bare wood ensures proper adhesion and a long-lasting paint finish.
