When it comes to installing a kitchen island cart granite top, there are several steps to follow. You need to start by calculating the amount of overhang for your countertop on your kitchen cart. This calculation should be based on the thickness of the granite as well as the installation area.
Next, using a notched trowel, spread a thin layer of thinset mortar over the kitchen island cart. Then, mix the epoxy cement as per the instructions and apply it onto the cart. Once it's completely dry, use a utility knife blade to remove the excess epoxy you may have squeezed out of the seam while applying it. Then seal the seams using a vacuum-powered seam puller.
