I have granite countertops in the kitchen. Recently I noticed there was a very think crack right where 2 slabs join each other. It is about 2 in away from the edge of the slab.
I'm looking for a solution to seal the crack. I have tried Liquid Nails but is is yellow in color and my granite is almost black with copper speckles.
What would be the best DIY way to seal it permanently and make sure it does not widen?
