Installation Instructions

Installation guides for fireplace hearths and surrounds

Please ensure you inspect the product fully when you receive your stone hearth. We take great care in selecting cutting stone for our customers, if however the hearth has any flaws you should notify us immediately. 

Stone hearths may have colour variation, veins and some inconsistencies. This should be expected with natural stone. However if you find any cracks or chips the Hearth should not be installed. No returns will be considered once the stone has been installed.

  • When installing Granite or slate hearths it is recommend to  ensure the area to be covered by the hearth is dust free flat and level, preferably solid concrete.
  • It is good practice to prime the area with PVA or SBR and the back of the hearth.
  • Allow the primer to dry, then bed the hearth down on a strong sand and cement bed with a medium consistancy. 

So why not take a look at our Build a Hearth page and design and purchase your own fireplace hearth.
