The bathroom granite vanity countertops are made up of a single slab of material such as granite that is also having a finished edge around your bathroom sink cutout. The finished edge means that your sink itself can be easily mounted to the underside of your counter, instead of hanging from the top & concealing the cutout's edge. Your bathroom sink is held in place on the counter underside by some special sealants that both bond your sink into place and also help to prevent water from leaking out through with the join at your sink's rim.
4 Easy Methods Of Installation Of Undermount Bathroom Sink To Granite
If you are going to install under the mount bathroom sink to your granite vanity without the help of any professional but you are confused about the procedure, then don't worry, you are in the right place. Here are the 4 easy methods to install the sink by yourself. Read and follow the given methods carefully to get the best result of your hard work:
Method 1: Mount The Sink Before The Counter
The vessel sinks & drop-in sinks are mounted after your counter has been placed properly on the granite vanity and sealed into proper place, under-mount sinks are needed to install first. It takes enough time for the sealant to cure wholly, holding your sink securely to the underside of your granite vanity. If the top is in place when your sink is mounted, granite gravity may work against your sealant, possibly pulling your sink away from your counter before it has enough time to dry properly. Instead, flip your counter upside down on a flat surface & attach your sink there. After 24 hours, your counter can be easily flipped back over and installed on your granite vanity.
Method 2: Start With A Clean Surface
When the granite counters are produced than a lot of dust that comes from the stone may get left behind on the underside of your counter, which is also rough and unfinished. This textured underside of the counter can trap & hold a lot of debris, which will definitely interfere with the bond betwixt the sink & your granite. Before attempting to mount your sink to the underside of your counter you need to clean it well with the help of a stone cleaner and also use a soft cloth. Let your granite vanity dry completely, the damp granite will appear always darker in color than that of dry granite. You need to wait for the color to return to its normal stage before applying the adhesive on it.
Method 3: Seal The Sink In Place
For most of the bathroom under-mount sinks, all you needed to mount your sink to your granite is a silicone adhesive. You just need to squeeze a very thin line around your sink cutout on the underside of your granite vanity. The weight of your sink will compress the adhesive slenderly and make it spread out carefully, so a thin line of silicone adhesive is all that is needed. Lower your sink into place, upside down on your countertop's underside, and then you have to lift it straight up again because this step will cause the silicone adhesive to pull away in the small "strings" from your counter to your sink. The air hitting these strings will make your applied adhesive bond even stronger. Lower your sink back into place and then you need to leave it undisturbed for at least 24 hours to dry. Once the applied adhesive is cured properly, you need to clean your sink with a clean cloth dipped in lukewarm water.
Method 4: Using Mounting Clips
The majority of the undermount sinks will only need adhesive to bond them to your granite vanity counter, but some large and oversized bathroom sinks will also use mounting clips. The small metal clip fastens on posts to both your sink and your granite vanity top. Epoxy is also used to attach the posts to both of your sink and granite vanity, then your clip is slipped over them & a small nut is secured down on each post to hold your mounting clip in place. The epoxy will cure hard enough to fasten your clips onto the posts in approximately 10 minutes, but your mounting clips still need at least 24 hours to dry properly before your counter is mounted into actual place.
