How to Install Silestone Countertops

Steven White

Silestone is a quartz compound countertop surface that comes in many colors, styles and textures. Silestone has bacteriostatic protection, making it an optimal surface for kitchen countertops. Unlike natural stone countertops, silestone will not absorb bacteria from foods. Installing Silestone can be completed by a homeowner, but silestone is heavy so it is advisable to have a friend help with the lifting.

Step 1

Position the countertop piece onto the cabinetry for a rough fitting. You’ll want to verify that the piece is plumb with the wall (lines up cleanly against the wall) and level with the surface (is not sitting unevenly).

Step 2

Mark any areas where the countertop must be cut for a joint using adhesive tape. Silestone joint pieces are available and can be cut to the exact size needed.

Step 3

Wash down the cabinet top surface and the bottom of the silestone with a sponge and mild soap. There cannot be any dust on the surfaces or they will not stick together. Allow the surfaces to dry completely before continuing.

Step 4

Cut the pieces to size using a wet saw, following the lines you made with the adhesive tape.

Step 5

Rough lay the pieces again, ensuring that they fit plumb and are level.

Step 6

Spray a thick bead of silicone caulking onto the cabinet surface.

Step 7

Set the countertop onto the cabinet and press down firmly. Install the large pieces first.

Step 8

Add more caulking to the sides of the cabinets where joints are being added. Press the joints into place against the cabinet, holding in place for several minutes.

Step 9

Wipe away any access caulk with a putty knife.

Step 10

Clean the top of the surface with mild soap to remove any remaining silicone residue.
