Quartz countertops are extremely popular to use in a modern kitchen remodel. Quartz is heat, scratch, and stain resistant, and has a nice, sleek finish to it. It is extremely durable, and is a timeless material that will continue to look great in your kitchen for years to come. Quartz counters can be custom made to fit into your dream kitchen, and are easy to install on your own. If you are considering installing this type of countertop in your kitchen, there are a few steps that you can take to make the process go smoothly.

Step 1 - Measure

Begin by measuring the counter space in your kitchen, to determine what size countertops need to be installed. When measuring, take into account the size of the backsplash if you are adding one, and how much room you will need to leave for it. You will have to buy a slab of quartz countertop either the same size of the area, or a little larger than the area that can be cut down instead. If you find one that needs to be trimmed or cut, mark where to cut on the quartz with painter's tape.

Step 2 - Cut the Quartz

Now that you have marked where you need to cut on the quartz countertop slab, you can prepare the saw. Attach the diamond blade, and plug it into an outlet nearby. Be sure before plugging it in that the saw is off so no one gets injured. Put on safety gloves and goggles to protect yourself while you work.

Start on one end of the countertop with the saw. Turn it on, line it up, and then use a spray bottle to get the saw damp. The water will help to prevent any burning that the heat from the saw may cause, as well as keep dust from obscuring the mark you made on the quartz. Press the saw into the quartz, and follow the mark. You will need to push down and forward while you cut through the material. Take your time so you get it done right. You likely won't get a second chance because buying a second slab of quartz is a large expense. When you are finished, measure each side to make sure that you have cut it evenly.

Step 3 - Install Countertops

Line up the countertop on the surface to make sure that it fits properly. Remove it when you know that you have the correct size. Apply construction adhesive to the top of the surface, and carefully and evenly place the quartz on it. Be sure to leave room for a backsplash if you are adding one. Use a level to make sure that you have the quartz countertops on properly.

Step 4 - Add a Backsplash

Fill a caulking gun with silicone. Apply the silicone to the back of the wall, and mount the backsplash. Use caulk to fill in any seams, and then wipe off the excess and allow it to dry.
