Repair Cracked Granite Hearth

Fissure any discussion of cracks in granite countertops must also include an explanation of fissures.

Repair cracked granite hearth.

Simply slapping some mortar on the crack will not solve a thing even if you bother to find some heat resistant mortar. Repair may be a moderately difficult thing since you really need to eliminate the underlying problem. Long or full thickness cracks and or areas with multiple cracks likely need repair. Granite countertops are relatively easy to take care of and such preventive maintenance as cleaning up spills quickly and avoiding setting hot pots on them will keep the surface in good repair.

I have even incoprorated glitter and crushed or chipped precious gems mixed in resin to fill cracks to make it look like a vein of precious drusy stone thus making it a unique stone inclusion. You can also remove a bit of granite dust from an area that is not visible such as the underside of a counter top. If you have an extra piece of the counter top material you can use this. Properly installed granite countertops are not likely to crack but if they do there are steps you can take to repair them.

In an easy to spot case of movement and separation between a fireplace hearth and the building floor take a look at the white caulk installed in an open crack between the hearth face and the floor in our photo left. Caulk is not a safe repair for hearth settlement. I work for a granite company never recommend marble as a hearth stone. The crack will just reappear.

Fissures are lines formed in the pattern of the stone by the borders of various crystalline groups within the stone. Connie phillips above has the best idea i have seen so far. You will need no more than 2 teaspoons of granite powder to repair most cracks under 1 foot 0 30 m long.
