Rusted Rod Repair (Crack In Front Of The Sink). NOVA Stone Care often gets a phone call about the crack that appeared in front of the sink. Customers usually think it’s an easy fix with an epoxy glue. Unfortunately, it is more complicated than that. Let’s explore the reasons why the crack appears in the first place. We will also explain the process used by NOVA Stone Care to tackle this common issue.
Why Crack Appears
The weakest part of any granite countertop installation is the area of the granite right in front of the sink. Typically this area is only 3″ wide from front to back. To strengthen this piece, many installers cut a channel in the underside of the granite and install a steel rod for support. Though this adds support, the steel rod can pose a problem down the road. If the adhesive used to secure the rod fails, it starts to rust. When this happens the expansion and contraction of the metal causes a fracture in the granite.
To fix the issue use, NOVA Stone Care technicians first break off or cut the piece of granite to expose the rusted metal rod.
The second step is to remove the rusted rod completely and clean the area thoroughly.
The next step is to glue everything back together using two part epoxy. This step might take a few hours until the epoxy is completely dry for the next step.
The final step is to clean and polish the granite.
Once we remove the entire rusted rod completely, there will be no internal expansion pressure from the rusted rod that will compromise the fixed area in the future.
