How to Install Undermount Granite Composite Sink
Step 1: Collect all the necessary tool
Before installing a granite composite sink, you will have to make sure that you gather all the necessary equipment that would help you in installing the sink.
For this purpose, you will need a power drill, screwdriver, clamps, mounting hardware, and a silicone sealant.
Without these tools, it will become difficult for you to install the sink. If you do not have any of the tools I mentioned in the previous line, you must grab them first.
Step 2: Find a perfect sized exiting hole
Granite is a very expensive material therefore, before buying it, you need to make sure that the size of the existing hole for your sink is perfect to secure an undermount the granite composite kitchen sink. If the wrong size is brought, you cannot cut it yourself to fit the exact size.
Unfortunately, many people bring the wrong-sized granite, and when they cannot install it, they try to cut them on their own and end up messing up with the expensive granite. Therefore, it is important to find the perfect size of the existing hole so that you do not have to cut it down.
Step 3: Measure and mark the layout of undermount clamps
The next thing that you should do for the installation is to measure and mark the layout of the undermount clamps. For this you should use a 2×4 dimension lumber as it will help you in installation.
To start this process, first of all, cut the length into 1 foot which should be longer than the hole in your countertop. Then, lay this cut length in the center of the sinkhole horizontally. Under the side of the countertop, clamp the sink with the help of a bar clamp.
While fitting them, avoid the tightening of clamps in the sinks as they can damage the granite. Instead of the clamps, you can also use a snug fit that will fit your sink into a proper position.
Now along with the top of the countertop, shift the 2×4 length a little longer and make sure that the granite does not get damaged during this process. Again, avoid over-tightening of the clamps as it can damage the granite.
Step 4: Drill the spots for installation
Take a close look at the placement of the sink and attach wing nuts onto the screw heads. With the help of a pencil, mark the spots of the mounting clips to get the drill spots.
These spots are at the wing nut location, and it is the place where you will drill holes. After marking the spots, remove the sink and drill the holes marked with the pencils at each point. To insert the tap in the holes, drill a little bit ¼ inch.
Do not be harsh while drilling the holes, rather be gentle so that the granite does not damage. Now find the spots where you will drill the holes to attach undermount granite composite sink. After marking the spots, remove the sink and drill those spots gently.
Step 5: Clean the ridge
With the help of the rubbering alcohol, clean the ridge carefully. After cleaning the ridge, use the silicone sealant around the edges. Now re-clamp the sink in the perfect spot that fits it in.
Step 6: Tighten the screws
Thread the wing nuts and tighten the screws for your granite undermount sink. Then, let the silicone sealant dry for almost twelve hours and check the leaks near the rim of your new sink. You should also consider calling a professional plumber for the plumbing fixtures.
