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.
Clean the surface of the cabinet of any loose debris or dust.
Cut a piece of 3/4" plywood that will sit flush with the edges of the cabinet.
Lay a 1/4" bead of caulk across the top of the entire cabinet frame.
Set the plywood on top of the cabinet.
Lay a 1/4" bead of caulk across the surface of the plywood in lines every six inches.
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.
Remove any caulk that has been extruded, with a putty knife and wash cloth.
Allow the caulk to set for 48 hours before applying any weight to the granite.
