Installing an undermount sink involves several stages, from preparing the countertop opening to securing the sink and sealing the edges. Based on the provided reference, key steps in the process involve making adjustments after the sink is initially set and properly handling the silicone sealant for a watertight finish.
Key Steps for Adjusting and Sealing an Undermount Sink
Once your oval undermount sink is initially placed within the countertop opening, with sealant applied and mounting hardware engaged, you may need to perform final adjustments and ensure the seal is correct before the sealant fully cures. The following actions are critical during this phase.
Repositioning the Sink Using Mounting Hardware
If the sink is not perfectly centered or aligned with the countertop opening after being set in place, you can often make fine adjustments using the mounting hardware, such as clips secured with wing bolts.
- Loosen Wing Bolts: If the sink needs adjustment, carefully loosen the wing bolts on the mounting clips. This reduces the tension holding the sink against the countertop, allowing for movement.
- Adjust the Sink: Gently maneuver the sink into the correct position within the opening.
- Retighten Bolts: Once the sink is properly aligned, firmly retighten all the wing bolts to secure the sink tightly against the underside of the countertop.
As referenced: "If you need to reposition a sink loosen the wing bolts adjust the sink and retighten the bolts."
Cleaning Up Excess Silicone Sealant
As the sink is tightened into place, excess silicone sealant will likely squeeze out from the gap between the sink flange and the countertop underside. Cleaning this up promptly is essential for a clean finish and a proper seal.
- Use a damp cloth to carefully wipe away any visible excess silicone sealant around the perimeter of the sink where it meets the countertop. Do this before the silicone starts to set.
As referenced: "Remove any excess silicone with your damp cloth."
Allowing the Silicone to Cure Properly
For the silicone sealant to create a strong, waterproof bond, it requires adequate time to dry and cure. This curing process ensures the sink is permanently sealed to the countertop, preventing water leaks.
- Allow the silicone sealant to dry for 24 hours. It's important not to disturb the sink or expose it to water during this curing period, unless the specific sealant manufacturer's instructions recommend a different time.
As referenced: "Allow the silicone to dry for 24."
These steps focus on the critical phase of adjusting and sealing the sink after initial placement, ensuring a secure and watertight installation.
