Step 1

Take Precise measurements of the cabinets using an instrumental inch tape, always take little more than the actual measurement. If you will take less measurement than the actual measurement then you will have to make joints and the grout will be visible which will look odd. Lay a ¾” plywood on top of the cabinets to support the granite.

Always add 1/2″ while measuring the granite slab for the overhangs for one side.


Step 2

Attach the plywood to the frame using screws and make sure that the plywood does not overhang to the outside of frame as the plywood will be clearly visible later. Also make sure that you tighten the screws properly using a screwdriver because if they will be loose than your countertop will also shake.


Step 3

Your walls may not have perfect edge so use a kraft paper or a stiffer material to make a template of the actual measurement. A template makes job easy as it is easy to move around. Scibe the slab if needed and using a circular saw which has a dry cut segmented diamond blade cut the slab carefully.

Put the granite slab on the sink counter and trace the exact dimensions of the sink counter. Then remove the slab and cut the dimensions using a jigsaw very carefully. Cover the sink to protect it until you join the granite seams.

Put the slab back safely after applying the bead and don’t use silicone caulk as after sometime it stains the slab, use acrylic caulk.


Step 7

Apply dollop of polyester based resin and add a small amount of color to match the color of the the granite. Using a putty knife mix the mixture and mix still it matches matches the color of the granite. Add the hardener and mix only on small area as you have only five minutes to apply. After it has dried about 30 minutes, smooth it out with a seam stone.

Put the slab back quickly and using firm pressure slowly settle the slab.


Step 8

Now that your installation process is complete it’s time to seal the countertop using a sealer to protect it from stains and further wearing out. Use a sealer specifically used for sealing granite countertops and apply it on the countertop and using a clean soft cloth spread it gently throughout.
