Product Description

If your facing will go on an uneven surface or if you simply need to raise your hearth by one-half inch, we recommend you use CV230 Micore 300 Board under the hearth.  It is a lightweight and dense fiber board that can act as a 'cushion' between the bottom of your stone hearth and the surface below it.  Micore board is 20 x 72 x 1/2" and comes in 2 pieces 20" x 36".  Note:  The Micore Board will be cut into two pieces to allow it to be put into a smaller box if it is ordered without a set of marble, granite or slate stone facing.  If your board is cut into pieces, they can be laid edge to edge.  MSDS

Also, be sure to view our special natural stone adhesive F26 designed especially for use with masonry products.  It won't bleed through the stone.

  1. Good price and fast shipping but packaging could have been better.

    Shipping was really fast and the price was great for the Micore 300. Unfortunately the corners were damaged in transit and broke, but in my case I don't need the full sheet so trimming is an option.

    Micore 300 Board is hard to find, and is a great component for use as an underlayment in your hearth. It is soft, so should cover it with sheet metal then cement board before applying the top cover of flagstone, ceramic tile, stone, etc.
