Interior and Exterior Repair Flashcards

A technician is repairing a fist-sized hole in a hollow-core interior door. After cleaning the damaged area, what is the correct first step in the repair process?

Answer: Fill the void behind the hole with expanding foam insulation.

For a large hole in a hollow-core door, the void inside must be filled first to provide a stable backing for the patch. Expanding foam insulation is used to fill this space, and once cured, it can be trimmed flush before applying a filler like spackle or auto-body filler.

When preparing to repair a small crack in exterior vinyl siding, which of the following is a critical initial step to ensure proper adhesion of the sealant or patch?

Answer: Cleaning the area around the crack with soap and water and allowing it to dry.

For any sealant, filler, or patch to adhere correctly to vinyl siding, the surface must be clean and dry. Dirt, dust, and mildew can prevent a proper bond, leading to a failed repair. Cleaning the area thoroughly is a crucial first step.

A resident reports a 'screw pop' on their drywall, where a small circular bump or crack has appeared. What is the proper procedure to repair this?

Answer: Drive a new drywall screw about 1-2 inches above or below the popped one, then remove the old screw and patch both spots.

A screw pop indicates the drywall has loosened from the stud. Simply hammering it back in won't solve the issue. The correct method is to re-secure the drywall to the stud with a new screw nearby. Afterward, the old, popped screw can be removed, and both screw dimples can be properly finished with joint compound.

When applying a new bead of caulk around an exterior window frame, what is the MOST important reason to completely remove the old, cracked caulk first?

Answer: To ensure the new bead of caulk has a clean, stable surface to adhere to.

Applying new caulk over old, failing caulk is a common mistake. The old caulk will continue to peel or crack, taking the new layer with it and causing the seal to fail quickly. Complete removal of the old material is essential for the new caulk to create a durable, long-lasting bond with the window and siding surfaces.

A maintenance technician notices that a ceramic tile on an apartment floor sounds hollow when tapped. What does this most likely indicate?

Answer: The tile has lost its bond with the thin-set mortar below.

A hollow sound when tapping on a ceramic tile is a classic sign of delamination, meaning the tile is no longer securely bonded to the substrate (the thin-set mortar and subfloor). This lack of adhesion creates a void underneath the tile, causing the hollow sound.

Which of the following materials is typically used to fill a small hole (less than 1/2 inch) from a nail or screw in an interior drywall wall during an apartment make-ready?

Answer: Spackling compound

Spackling compound is specifically designed for filling small holes, cracks, and dents in drywall. It dries relatively quickly, sands smoothly, and is ready for priming and painting, making it the ideal material for minor drywall repairs common in apartment turnovers.
