WALMART MAINTENANCE Carpentry and Structural Repairs 4 — Questions and Answers
Question 1: When repairing a sagging ceiling tile in a retail environment, what is the FIRST step before starting work?
- Replace the tile immediately to prevent hazard
- Cordon off the area below and notify a supervisor (Correct answer)
- Apply adhesive from a ladder without barricading
- Wait until the store closes to begin repairs
Correct answer: Cordon off the area below and notify a supervisor
Cordoning off the area and notifying a supervisor protects customers and staff while following proper safety protocol.
Question 2: Which type of wood joint provides the strongest connection when repairing a load-bearing shelf bracket?
- Butt joint
- Miter joint
- Mortise and tenon joint (Correct answer)
- Lap joint
Correct answer: Mortise and tenon joint
The mortise and tenon joint provides superior strength and load resistance, making it ideal for load-bearing applications.
Question 3: A maintenance tech notices a wooden door frame has swollen and the door no longer closes properly. What is the most likely cause?
- The door hinges are too loose
- Moisture absorption causing wood expansion (Correct answer)
- The door was installed with incorrect clearance
- The floor has settled unevenly
Correct answer: Moisture absorption causing wood expansion
Wood naturally absorbs moisture and expands, which is the most common cause of door frames swelling and doors sticking.
Question 4: What is the correct procedure for patching a hole larger than 6 inches in diameter in drywall?
- Fill entirely with joint compound and sand smooth
- Use a California patch with backing board support (Correct answer)
- Cover with a peel-and-stick patch kit only
- Apply fiberglass mesh tape directly over the hole
Correct answer: Use a California patch with backing board support
Holes larger than 6 inches require a backing board or California patch method to provide structural support for the repair.
Question 5: When installing replacement baseboard trim, what angle should corner miter cuts typically be made at for a standard 90-degree corner?
- 30 degrees each piece
- 45 degrees each piece (Correct answer)
- 22.5 degrees each piece
- 60 degrees each piece
Correct answer: 45 degrees each piece
Two 45-degree miter cuts (one on each piece) combine to form a clean 90-degree corner joint.
Question 6: A wooden pallet storage rack shows signs of wood rot at the base posts. Which action is MOST appropriate?
- Paint over the rot to seal it in
- Take the rack out of service and replace the damaged posts (Correct answer)
- Reinforce only the visible surface with wood filler
- Reduce the load on the rack and monitor monthly
Correct answer: Take the rack out of service and replace the damaged posts
Structural wood rot compromises load-bearing integrity and the rack must be taken out of service until rotted components are replaced.
Question 7: What type of fastener is BEST suited for attaching a heavy wall-mounted display bracket to a concrete block wall in a Walmart store?
- Wood screws with plastic anchors
- Masonry anchors (sleeve or wedge anchors) (Correct answer)
- Drywall toggle bolts
- Standard lag bolts driven directly into concrete
Correct answer: Masonry anchors (sleeve or wedge anchors)
Masonry sleeve or wedge anchors are specifically designed to provide secure hold in concrete block walls under heavy loads.
