My installer screwed 3/4 inch plywood on top of my cabinets. Then he put liquid on top of the plywood, then the undermount sink and then more liquid glue then the granite counter (3/4 inch thick). To seal the top of the sink rim to the granite top, he used clear silicone for windows and doors.

Did he do it correctly? I thought he was supposed to use silicone for everything.

Please help so I can sleep well tonight.

Glue (not sure which type he used) is better for the granite.
Clear silicone was used because it's a better water proof seal where water is present. The granite is so heavy that it ain't going anywhere anyway.

Sleep well

There is more than one way to skin a cat, you know!

My sinks are held up to the granite by mechanical (metal) kits that lift the sinks into place. Plywood is another way that some installer do it. Either way, silicone is always used to seal things.

Like Duke said, sleep well.
