How to Install a Quartz Countertop


Quartz countertops are a popular choice for kitchen remodels. In addition to having a lustrous finish, quartz is stain, heat, and scratch-resistant. Thus, it is a timeless and durable material that will look fabulous for many years. Quartz counters are easily installed and can be customized to fit any kitchen. If you are thinking of installing a quartz countertop, here are some easy steps to follow.


Step 1: Measure Materials

Measure the counter space to find out what size countertops you need. Be sure to account for the backsplash if using one. You will need to purchase your countertop in the size of the area, or bigger than the area and cut it down. If you get one that has to be cut or trimmed, use painter’s tape to mark where the quartz needs to be cut.


Step 2: Choose and Order your Quartz

There are many choices available. When you are looking through the numerous options, first concentrate on finding a pattern and color that suits your kitchen. Quartz countertops are available in basic whites and blacks with refined marble detailing to elaborately fashioned surfaces that accurately represent stone.

Next, select the proper thickness. Most quartz is available in 1-1/4-inch slabs, which is great for kitchens. Lastly, select your preferred edge. round, curved, waterfall and square edges are available. Unpolished edges are necessary to form seams between slabs; however, the space design or your personal taste should determine your remaining edging choices.


Step 3: Prepare the Area

Once you have ordered your slabs, spend some time prepping the area where the countertops will be installed. Start by removing all existing surfaces or countertops so just the cabinets are left. Using a level, look to see how the tops of the cabinets line up. Add wooden shims wherever necessary to create an entirely level surface across the whole countertop space. Also, be sure to shut off your water. Lastly, stain, seal or paint the cabinets prior to installing the countertops and let dry.


Step 4: Dry Fit Your Quartz

When you receive your quartz slabs, carefully place them across the top of your cabinets, exactly where you want to install them. Get someone to help you move the slabs because they will likely be extremely heavy.

If you only ordered one slab of quartz, be certain that it fits tidily into place without leaving big gaps. If you purchased several slabs of quartz to create a more intricate countertop, be certain that they fit together properly. Also, slip the sink into its spot to make sure that it fits correctly as well.

If all the slabs fit properly, installation can begin. On the other hand, if the quartz needs adjustments use a pencil and painter’s tape to mark spots where cuts need to be made. Cut with a circular saw using a diamond blade.


Step 5: Install your Sink

Before installing your sink, remove the quartz slabs. To prevent damage, store the slabs in an upright position. Also, always get someone to help you when lifting the slabs as they are very heavy. After clearing the surface area, drop your sink into the proper spot. Make sure it has sufficient support. Do not add plumbing until the countertop installation is complete.


Step 6: Install the Ledgers

Quartz countertops do not require underlayment or sub counters for additional support like granite does. Rather, quartz counters can be placed directly on top of the cabinets. That said, quartz counters are heavy and might need added support in some spots.

Examine the countertop layout and search for places where cabinet support is lacking. For instance, if you are adding a desktop to a spot that does not have adequate support, or installing a counter across a big dishwasher, install ledger boards as needed. Usually, fastening 1 to 2-inch ledgers into the cabinet siding or wall adds enough support.


Step 7: Protect your Cabinets

Prior to positioning the quartz slabs, spend a little time protecting your cabinet faces. Around the top cabinet edges, apply painter’s tape to keep silicone adhesive from coming in contact with your cabinet faces. Do not forget to remove the tape before the adhesive dries.


Step 8: Install your Countertop

Beginning with the part that goes around the sink, install your quartz slabs one piece at a time. Apply silicone glue to the tops of the cabinets below in order to anchor the slab in place. Place beads of silicone glue 6 to 12 inches apart to make sure that the counter is held securely.

While the glue is wet, lower the slab in place with someone’s help. Gently press the slab to be sure it is entirely secured to the cabinets beneath, repeat for remaining slabs.

If you are using multiple slabs, it will be necessary to seal the joints. Line both sides of the seam at the top with painter’s tape. Apply silicone glue or recommended material on the joint. Fill the seam and let the material dry. Take off the painter’s tape before the silicone is dry. Let the countertop set overnight before using.


Step 9:

Once your countertop is entirely installed you can hook up your drain and sink. Turn your water back on and you are all set!
