You can try 2 part epoxy. The best fix might be to have a granite installer color match some epoxy and sand it smooth. Depending on the color/pattern you have it may be less detectable.
Epoxy is best for granite.
First, everything on the countertop must be uninstalled. Then, measure the area the granite should cover and cut the granite to size. Glue down the granite and reinstall faucets, etc.
Epoxy or silicone glue will do it
A lot depends if any weight is going to be suspended on the glue. -If not, I would use a construction adhesive like PL200.
Epoxy is definitely the best for rocks and slabs of granite. Make sure the surface where epoxy is going is totally dust free !
We use two component epoxy when we need to fix any stone.
granite, glue, gypsum
Depending on the weight and form of the granite, PL200 may work. If not that then more expensive glues like PL Premium would definitely work
I would use PL Premium or similar
Silicone is best for that.
That depends very much on the glue that was used. -You should contact the person or company that did the install and ask their advice.
DUO eyelash glue is the best.
i use granite gold cleaner.
