Kosmus Granite Countertop
We are about to install Kosmus granite counter tops.
It seems to have a lot of mica in it and my installer has told me that it is a very brittle granite, will be difficult to seal and take care of.
We did not buy it from him (he is just installing it) and I'm not sure if he is just trying to get us to buy something else from him. It is a beautiful slab that i fell in love with. Thanks for your help. Kathy
Your installer is correct. Kosmus granite counter top slabs do tend to be brittle from all the mica, can easily cleft and crumble upon fabrication/installation and often will scratch and chip easily. It also tends to be expensive.
Don't know how you bought a slab independent of a fabricator/installer. Stone warehouses do not sell slabs to the public. You have to be a fabricator or installer (someone who knows how to handle heavy stone without killing someone).
The homeowner hires an installer who purchases the slab on behalf of the owner, has it cut and installed.
So, I don't think the installer is trying to get you to buy something from him. He is just being a good stone professional alerting you to the potential drawbacks of your choice while you still have a chance to do something about it.
Also, it makes his job potentially much more difficult since such a stone could break even if he's very careful and does everything right. Then he's on the hook for another granite countertop slab and maybe another round of the same problem.
But on the flip side, it is a dark, dense granite and it may be just fine. Remember, granite is a natural product. Every slab is unique and different slabs even of the same color/variety may perform differently. Sometimes poorly... other times no problem.
There are some stones that may be beautiful, but are commonly so difficult to work with that many installers will try to talk you out of it.
It only makes sense. If you were a painter and were asked to paint a house using a paint that you knew could suddenly change color... well you really wouldn't want to work with it. Good Luck
