Guidelines | How To Install Undermount Bathroom Sink To Granite
A number of precise cutting and sealing are ahead. But, at the end don’t rush and turn it into a fruitless toil – take drying time into considerations.
Step 1: Clean the Surface
First, you need to clean out the granite surface. Whilst granite counters are produced, they leave a significant amount of dust on the underside. These dust & debris can interfere between the bonding of silicone adhesive & the granite surface. So clean the underneath of the counter with a soft cloth before applying adhesive.
Step 2: Applying Silicone
After you have cleaned the granite you need to apply Silicone to seal the sink to the countertop. But you can’t apply every other Silicone caulking material. There are some silicone adhesives that have water repellent properties to bond the ceramic countertop. Make sure there aren’t any gaps anywhere.
Step 3: Clamping the Sink into Position
For this part, you need a regular 12-inch bar clamp that detaches to hold the sink in position. Slide the long end of the clamp through the drain & attach the top of the clamp, make sure that the drain is not clogged. If so, then follow the steps to unclog the bathroom sink drain. Then, you can bring your sink right up to the countertop. Make sure the sink is perfectly aligned to the edges of the granite.
Take a strong piece of solid wood to brace the sink up underneath the slab with a clamp while it’s drying. Leave the clamp a little bit loose so that you can make some to the sink position. When you are sure you have an even lip all the way around your sink. Once your sink is perfectly in position, tighten down the clamp the rest of the way.
Step 4: Strapping
To make sure your sink doesn’t fall off you have to strap the underneath. You have to use galvanized hanging straps right along the center of the sink. You can screw the ends of the strap at the sides of the cabinets. Along with the silicon, this strap will perfectly hold the sink to its place.
Make sure you cut the excess parts of the strap so that no hand’s cut by those sharp edges.
Step 5: Detaching the Clamp
After strapping the sink underneath, you can detach the clamps slowly without any worries of the sink falling off. The strap is in place to hold the sink against its own weight as the silicon dries off slowly. After detaching you can make some final checking whether everything is in the right position or not.
Step 6: Finishing Touches
Take a bit of acetone or rubbing alcohol on tissue & scrap the excess silicone off the sink. This also helps the glue to bond to the surface more easily. Smooth out the adhesives underneath the sink with your fingers to get that silicone all around the surface.
Step 7: Wait!
Now, after all the hard work is done, go get a drink & let the adhesive dry off. Be sure to follow the manufacturer’s guidelines on the drying time. After it is dried off, the plumping work can be performed.
Wrap Up
Before doing any DIY task, having your research done thoroughly means half of the work is done already. Don’t rush into doing things. Make sure you take every step carefully, otherwise it may lead to accidents. Last but not least, don’t be shy if you need an assist from a friend to ease your work.
