Will sealant change the color of my marble countertop?
We are having honed valley gold marble countertops installed soon. I'd always assumed sealing them was the thing to do. But, the stone fabricator wants to do a sample because he says sealing is going to change its color. Now, I'm nervous! But, I've seen so many beautiful photos of sealed Calcutta and Carreras on this site and never noticed any graying...I'm feeling as though regardless of any color variance, sealing should be the priority...yours tips and wisdom would be so welcome!
