Hi @dekeykunsang,

Generally, when a vanity waste is installed, a plumber would use Plumbers Putty under the part of the waste on the top side of the vanity. If you didn't do this, I would suggest removing it, cleaning up whatever silicone you have used and replacing it with plumber's putty.

Make a sausage with the putty and then sit it in a circle around the hole in the vanity. When the waste is tightened on, it will compress creating the seal you are aiming for.

Let me know what you think and if you have further questions, please don't hesitate to ask.
