If you don’t trust the fabricator about sealing, should you really be trusting them to fabricate exotic stone slabs?

Good point. We are building in a rural area so not a lot of choices but went with a fabricator with a good reputation based upon word of mouth. I trust them with the fabrication. The skill of sealing on site comes down to the worker bee and how thorough they are. This is the part that is more risky IMO. I guess I can let them do it and follow behind them like a puppy dog making sure they do not leave anything sitting on top.

Just thought I would chime in here. I too have been looking at quartzite and spoke with a fabricator yesterday. He said all quartzite should be sealed, just like granite. But he doesn't do it on site because they use a wet saw and the quartzite will need to dry completely before sealing so when it gets installed it may still have some water content and should be sealed in the home after it sits for a couple of days. Anyone else come across this advice for a fabricator?

Agree with @Shannon_WI... you can seal it yourself very easily.

Thanks to all who posted. I am so tired of fabricators saying that everything needs to be sealed. They said that about my black galaxy too...it should be sealed “just in case”. This is simply NOT true and I would almost rather risk a few stains that are unlikely to ever happen vs. dealing with hazy granite with sealer sitting on top of it. I will tell them I am sealing it myself.

Marilyn…. i think uou are 100 percent correct and hit the nail on the head. i had quartzite installed 3 weeks ago. upon instsll, i asked the installer why the esges of the island and certain areas along the cointertop wall were darkened and looked saturated wet. he said they were wet from cutting and will dry in a few hours. well 3 weeks later they arent dried!! and they arent dry because the installer applied the sealer at install!! the water is trapped and cannot evapoorate.

the fabricator said he has no idea why this happened, they are replacing it, but the only logical explanation is EXACTLY what you stated. Im glad they are replacing it, but for 3 weeks i have been wrackong my brain about what it could be, behan searching for alternarive stones for fear of using the same quartzite and having it happen again, only to realize, it eas the improper install that caused thsi mess!
