Choose between rounded, curved, and square edges for the outer edges of your quartz. Use 1. 25 inch (3. 2 cm) slabs for the best results. Select a pattern and color that fits with your space. If you have the tools to cut your countertop yourself, make a large template of your existing countertop with balsa wood or rigid cardboard first. Once all the pieces of your template are glued together, lay them down on your quartz slab and trace around them. Add an extra 1⁄2 to 1 inch (1. 3 to 2. 5 cm) to your dimensions to account for overhang.

Quartz weighs 25 pounds (11 kg) per square foot, so have at least one person help you move the slabs to be safe. If you’re using multiple quartz slabs, make sure that each one fits tightly against the other. If you removed your kitchen sink when removing your old quartz, lower it into place after dry-fitting your quartz to make sure that it fits. If your sink is still installed, that’s fine too.

Make sure that there are 4 lines total—the top, bottom, and 2 side lines.

Be sure that your blade is designated for quartz. Skip this step if you already have a diamond masonry blade on your power saw.

Always check that the teeth of the diamond blade are pointing opposite to the quartz. Repeat this process with the other side of the quartz to cut it in half. Remove the blade from the quartz every 30 seconds to keep the temperature low.

Always apply a ribbon of plumber’s putty before installing the faucet and sprayer bases. Use caulk to attach the sink rim to its opening. Seal the drain and tailpipe with caulk or with a gasket—whichever the manufacturer recommends. Be sure to turn your water on and check for leaks before installing your quartz.

Purchase painter’s tape from any home hardware store or online supplier.

Attach each ledger using an electric drill and the screws provided. Purchase ledgers from home hardware stores. Be sure to take measurements of the areas that need ledgers before purchasing any.

Always start installing the quartz around the sink region.

Work as fast as you can so that the adhesive is still wet before you lay down your quartz.

Be sure to lower the slab onto the adhesive while it’s still wet. Have a friend help you lower each slab into place.

Check the manufacturer’s instructions for drying time. Take off the painter’s tape before the sealant dries.
