How to know if granite was sealed before or not?

Question

We got new countertops installed. It's light colored granite and everytime a small drop of water 'hits' it, it gets absorbed into the granite and leaves a dark spot, which dries later. It's not like I don't wipe off water spills, but I don't think granite is supposed to absorb water this fast. This leads me to thinking that granite has not been sealed. Do you think it's true?

Answer 1

I also believe it has not been sealed.  All the stone counters I have seen would have beaded water spilled on them.  

Be careful not to get it dirty before it can be fixed.  Oil would be really bad.

Answer 2

Granite countertops even when sealed will Soak up water and Liquids depending on what sealer was used. I would Highly suggest purchasing a High end Impregnating Sealer and doing the whole kitchen. Rub it on let it sit for about 10 Minutes and then wipe off. You should notice a Big difference in water beading on the surface. Alot of countertop shops do not seal them when they are Installed. Some that do seal them use a non Impregnating sealer.
