Hello everybody. I'd love to hear from anyone who has used Della Terra Quartz on kitchen countertops. I am about to change my kitchen countertops (huge investment) so I just want to make sure I select a material that is not going to stain or chip easily. My installer has said that he would seal the quartz. A few (probably silly) questions:

- Is this quartz porous? I understand that other products like Cambria do not need a sealer.

- Do sealers wear off?

- Would you recommend any other brand over Della Terra?

This is a considerable expense so I just want to make sure I do my research first. Thanks so much for your advice.
