I have repaired cracks on that type granite. The difficulty I had was making the repair invisible, it all depended on what angel you viewed the repair. Plus the crack was only in front of the sink, so it was not as large. I would recommend the following:

1.       Use shims to level.

2.       Use sharpies to darken the white areas in the crack.

3.       Using gel CA and tints fill the crack trying to match the surrounding area.

4.       Scarp down with razor blades.

5.       Grind the area level, so when you run your fingers across the repaired area, you don’t fill the crack.

6.       Hone up to 3000.

7.       Use thin or gap filling CA to fill any new voids that may have developed when leveling the area.   

8.       Use black tinted  tin oxide and Alpha buff pads polish to high gloss.

9.       Finish off with Enrich and Seal.

The reason it cracked was either a painter stood on it to paint or it was a fissure in the stone and it devolped into a crack.Fissures on not that common in that particular granite.Put a small shim on both sides of the crack, inbetween the granite and cabinet.Scrape the seam as much as possible,fill with akemi and polish away.The owner already stated they know it wont match exactly.Make sure you shim it tight so it doesnt vibrate. They will be happy.

Hi all:
 
Received permission from customer to share with group. Granite is cracked all the way through, about a 7 year old install. I have only done seam repairs and small cracks. Does this need to done by a fabricator with some vacuum clamps? Or is it toast. Advice would be helpful.
 
Thanks:

Hello Don;
 
We have a slab on granite in our kitchen which had developed a crack in it (picture attached). The company who had installed this came out to look at it and told us there is nothing they can do except try and replace the slab but it would not match the other slabs we now have in our kitchen. Is this something that could be repaired? We understand that visually it can not be restored but we would like to keep this slab from further deterioration.
 
Please let me know if there is anything that can be done.
 
Thank you,
