Undermount Stainless

How I can intall a stainless steel sink, granite countertops?
A granite plate should fit on 3 / 4 "against plywood. Place the timber on top of your cabinets. Cut the area of the basin in your sink (more than 1 / 4 ") and the sink top plywood (the edge of the pool will rest on the top of the plywood and cons that should be able to replace the sink and the room about half-inch in all directions). With a pencil, trace around the edge of the sink, remove the sink and routed to the place where the lip will sit about 1 / 16 inch in depth (or thickness of the sink) and about 1 / 4 inch wider than the sink. Place the sink in the hole. Place granite countertop over cons-plated and sink. Move around the sink in the hole until it is centered in the hole in the granite. Then, seal the edges of granite kitchen sink with a silicone sealant transparent.
