WALMART MAINTENANCE Carpentry and Structural Repairs 2 — Questions and Answers
Question 1: A maintenance technician is repairing a ceiling tile grid in a Walmart store. The main tee runners should typically be spaced how far apart?
- 12 inches
- 24 inches
- 48 inches (Correct answer)
- 16 inches
Correct answer: 48 inches
Standard suspended ceiling main tee runners are spaced 4 feet (48 inches) apart to support standard 2x4 ceiling tiles and cross tees.
Question 2: Which type of wood joint is commonly used to reinforce a corner connection in shelving units and fixture repairs?
- Butt joint
- Dovetail joint
- Pocket screw joint (Correct answer)
- Finger joint
Correct answer: Pocket screw joint
Pocket screw joints use a jig to drill angled pilot holes and are fast, strong, and widely used in retail fixture repairs and cabinet assembly.
Question 3: When caulking around a door or window frame in a Walmart store, which caulk type provides the best adhesion to both wood and metal while remaining paintable?
- Pure silicone caulk
- Latex-based paintable caulk (Correct answer)
- Butyl rubber caulk
- Polyurethane foam sealant
Correct answer: Latex-based paintable caulk
Latex-based paintable caulk adheres to wood and metal, is easy to apply, cleans up with water, and can be painted to match surrounding surfaces.
Question 4: A Walmart maintenance team is replacing a section of damaged concrete floor near a loading dock. After removing the damaged section, which step must come BEFORE pouring new concrete?
- Apply a waterproof membrane over the existing concrete
- Prime the existing concrete edges with a bonding agent (Correct answer)
- Install rebar on top of the new concrete after pouring
- Cover the area with plastic sheeting for 24 hours
Correct answer: Prime the existing concrete edges with a bonding agent
A concrete bonding agent must be applied to existing concrete edges to chemically link the old and new concrete, preventing delamination and cracking at the joint.
Question 5: What is the correct technique for driving a nail flush with a wood surface without leaving hammer marks?
- Use a rubber mallet for the final strokes
- Use a nail set to drive the nail the final 1/8 inch below the surface (Correct answer)
- Pre-drill a pilot hole and drive the nail by hand
- Apply masking tape over the nail head before striking
Correct answer: Use a nail set to drive the nail the final 1/8 inch below the surface
A nail set is a small punch tool placed on the nail head that allows a technician to drive the nail slightly below the wood surface without damaging surrounding material.
Question 6: When repairing a squeaky wood floor in a Walmart employee area, what is the most effective long-term solution?
- Apply lubricating oil between floorboards
- Drive screws through the subfloor into the floor joists to eliminate movement (Correct answer)
- Place heavy objects on the squeaky area overnight
- Sand the squeaky boards to reduce friction
Correct answer: Drive screws through the subfloor into the floor joists to eliminate movement
Screwing through the subfloor into joists eliminates the movement between the subfloor and joists that causes squeaking, providing a permanent mechanical fix.
Question 7: A Walmart maintenance technician must repair a 6-inch diameter hole in a drywall ceiling. Which repair method is most appropriate for this size of damage?
- Fill entirely with joint compound and sand flat
- Use a drywall clip (California patch) with a new drywall piece (Correct answer)
- Apply self-adhesive mesh tape only
- Use spackling paste and a putty knife
Correct answer: Use a drywall clip (California patch) with a new drywall piece
For holes larger than 4 inches, a backing support such as a drywall clip is required to hold a new drywall patch in place before applying joint compound.
