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.

The use of less adhesive enables removing the hearth easier in the event that it breaks. If you have an uneven floor, use glue to cover the whole circumference of the hearth and avoid rounding the corners. The foundation might be levelled by placing a thin set bed underneath the hearth if the floor is extremely uneven. Just cut the legs to a sliver. Always cut on a level surface, and never allow the piece to fall while you’re working.

Good masking tape is used to protect the marble from being scratched during the installation process. Always begin cutting at the polished edge, because a blade chip will be on the unfinished edge, which will be covered by the mantle leg, if you start at the unfinished edge. Make your cuts with a cleaned side looking up. Because of the shape of the firebox, it may be preferable for the header to follow the box, even if it isn’t quite level. Our fireplace mantels are designed to accept up to 5″ of facing material on each side in most situations.
