How to Attach a Granite Countertop to a Cabinet

Granite is one of the most elegant and popular countertop surfaces available, and its inherent strength makes it perfect for this purpose. Installing granite is a relatively simple process but may require someone to help you to lift the stone since its strength also makes it very heavy. Your cabinet should be strong enough to support a granite surface, and most are, but you should consult with the manufacturer if you are unsure.

Step 1

Clean the surface of the cabinet of any loose debris or dust.

Step 2

Step 3

Lay a 1/4" bead of caulk across the top of the entire cabinet frame.

Step 6

Place the granite countertop on top of the plywood in its proper position. Do this in a manner that permits you to lower the granite directly into place so you do not have to shift it excessively to get it into the proper position.
