How Do I Cover Tile Countertops With Thin Quartz?

Measure the surface to be covered and create a template on graph paper. Indicate the cut-outs you will need for the sink, cook-top or any other fixtures. Indicate the areas where you want to have a backsplash.

Select the quartz surface you want to use and order the material from the manufacturer. It will be prepared with the cut-outs you indicated, and the edges will be radiused for smoothness. Sheets are usually 120 inches by 55 inches, and you want large pieces with minimal joints. Thicknesses are 3/4 inches to 1 1/2 inches.

Remove the old surface and clean the counter, leaving it dry and dust-free. If the surface is not level, use a leveling paste to correct the problem. Apply a thin layer of paste (no more than 1/4 inch thick) with a wide putty knife. Feather the edges with the putty knife and check to see if the surface is level. Reapply as needed until the surface is completely level.

Spread a bed of thin-set mortar on the surface to be covered, or apply a continuous bead of adhesive to the back of the quartz.

Set the quartz on top of the thin-set mortar bed, lining up the back side first. Apply pressure by hand or with a rubber mallet to bond the quartz to the mortar and to get the piece level. Leave only a hairline crack between each piece. Install the counter first and finish with the backsplash.

Fill in the joints with a joint sealer using a putty knife. Remove any excess joint sealer with a damp sponge.
