What Happens During Granite Templating and Installation

By the time the last template strip is glued to its neighbor on the cabinets, the shape of the whole job is fixed. A granite countertop in Riverside, CA moves through more separate steps than most owners count, and the pace is closer to granite countertops riverside daniel ritchie than to a one-day promise. Templating comes first, then cutting, shaping, setting and plumbing, with cure time between several of them.

Templating on the cabinets

The shape is captured either with a digital laser system or with thin strips and plywood laid across the cabinet boxes. Either way, the template records wall angles, the sink location and the cooktop opening. Walls in older Riverside homes are rarely square, so the template follows what is there, not the drawing.

Cutting the slab

The fabricator lays out the pieces on the slab so veining runs the right way, then cuts with a bridge saw or with waterjet and CNC equipment. Water cools the blade and holds the dust down. Granite, quartz and quartzite all cut this way, though harder stone wears blades faster.

Cutouts and corners

Sink and cooktop openings are cut with a radius at each inside corner, never a sharp square. A square corner concentrates stress, and a crack can start there from the weight of the stone or a knock during carrying. A rounded corner spreads that load. Dry heat and temperature swings from Santa Ana winds in the Inland Empire make that small radius worth the extra pass.

Edge profile and polish

An eased edge, bevel, bullnose or ogee is shaped first with coarse tooling, then polished in stages with finer abrasives. Not every edge profile suits every slab thickness, so the choice is checked against the stone before cutting. An ogee needs more material than an eased edge, and a thin slab may need a built-up front.

Seam placement, setting and hookup

Seam placement is decided on the plan, usually away from the sink and cooktop where stress runs highest. The joint is filled with color matched epoxy or polyester adhesive, then drawn tight and leveled with seam setters. A seam can be made tight and well matched, but it will still be visible up close. Undermount sinks hang from the underside of the stone on clips or brackets with adhesive, and the joint is sealed with silicone.

Any overhang at a bar or island needs support. A long overhang gets steel brackets or corbels, because unsupported stone can snap at the cabinet edge under a leaning adult. After the stone is set, the adhesives need time to cure. Only then does the plumber reconnect the sink and faucet. The surface should be treated gently for a while after the installers leave, since the glue and silicone are still hardening.
