WALMART MAINTENANCE Carpentry and Structural Repairs 1 — Questions and Answers
Question 1: When repairing a damaged drywall section in a Walmart store, what is the minimum number of screws required per stud when attaching a new drywall patch?
- One screw per stud
- Two screws per stud spaced 12 inches apart (Correct answer)
- Three screws per stud
- Four screws per stud
Correct answer: Two screws per stud spaced 12 inches apart
Standard drywall installation requires fasteners spaced no more than 12 inches apart on studs, meaning at least two screws per stud for proper holding strength.
Question 2: Which type of screw is most appropriate for fastening drywall to metal studs in a commercial retail environment?
- Wood screws with coarse threads
- Self-drilling drywall screws (Type S) (Correct answer)
- Lag screws
- Sheet metal screws with hex heads
Correct answer: Self-drilling drywall screws (Type S)
Type S (self-drilling) drywall screws are specifically designed to penetrate metal studs without pre-drilling, making them the correct choice for metal stud framing.
Question 3: A store maintenance technician needs to locate studs behind drywall before hanging heavy shelving. What is the standard stud spacing in most commercial construction?
- 12 inches on center
- 16 inches on center (Correct answer)
- 24 inches on center
- 32 inches on center
Correct answer: 16 inches on center
16 inches on center is the most common stud spacing in commercial and residential construction, providing structural support and meeting code requirements.
Question 4: When installing a hollow-wall anchor (toggle bolt) in drywall to hang a moderate load, which step must be completed FIRST?
- Drive the anchor into the wall with a hammer
- Drill a hole slightly larger than the toggle bolt body (Correct answer)
- Tighten the screw fully before inserting into the wall
- Apply construction adhesive to the anchor wings
Correct answer: Drill a hole slightly larger than the toggle bolt body
A properly sized hole must be drilled first so the collapsed toggle can be inserted through the wall and spring open on the other side.
Question 5: What is the primary purpose of using a moisture-resistant (MR) drywall in Walmart restrooms and break rooms?
- It is cheaper than standard drywall
- It resists mold and mildew growth in high-humidity areas (Correct answer)
- It provides better soundproofing between rooms
- It is easier to paint than standard drywall
Correct answer: It resists mold and mildew growth in high-humidity areas
Moisture-resistant drywall contains fiberglass additives and a water-repellent facing that inhibit mold and mildew in areas with high humidity such as restrooms.
Question 6: A door frame in a Walmart stockroom is out of plumb by 3/4 inch. Which tool should the maintenance technician use to verify the frame alignment before making adjustments?
- Tape measure
- Speed square
- Level or plumb bob (Correct answer)
- Chalk line
Correct answer: Level or plumb bob
A level or plumb bob directly measures vertical alignment (plumb), making it the correct tool to identify and correct a door frame that is not perfectly vertical.
Question 7: When replacing a damaged interior door in a Walmart facility, the pre-hung door must be shimmed during installation. What is the main function of door shims?
- To provide a decorative finish around the door frame
- To fill gaps between the door frame and rough opening for proper alignment (Correct answer)
- To reinforce the door hinges against heavy use
- To weatherproof the door against temperature changes
Correct answer: To fill gaps between the door frame and rough opening for proper alignment
Shims are tapered wedges inserted between the door frame and the rough opening to level and plumb the frame within an opening that may be uneven.
