How to Install a Marble Fireplace Surround

In means to give a border among the hearth and the ground floor. Set up the hearth on the Micore such that the polished edge of the hearth faces away from the firebox.

It should be centred on the Micore so that you would then not have to move it. To finish the hearth’s perimeter, apply glue around the edge, leaving two handholds, then a couple of “squiggly” lines down the middle of the hearth. Make sure there are no cavities around the edge that could cause a corner to shatter when someone walks through it. Lower the hearth slowly but steadily; the weight of the marble may cause it to break if it is left flat for an extended period of time. The hearth is extremely heavy, and the weight of the component helps to hold it in its proper place.
