Quartz never needs sealing as it is mostly plastic and resin. I would say contact the manufacturer but you have ruined your warranty by having the refinisher touch the tops. I am afraid at this point you are stuck and at their mercy unless you want to change out the tops.

Oh boy. The counters are t ‘defective’. You admit to damaging them by using the wrong cleaner on them and thereby damaging the surface. You hired a ‘professional’ to resurface them who then put sealer (?!?!?!) on them which is just sitting on top. I’m not a quartz expert and I have no idea how to fix it at this point.

I understand. The guy is telling me they’re defective bc they shouldn’t do that after refinishing.

They are plastic and resin, everything you do to these tops without the proper protocol and training is just going to make them worse. You started the train down the wrong tracks with the BKF and this so called stone restorer has taken this onto the dirt path at the end of the tracks. There is and was nothing defective from what you have described. This will all be on you unless you have some luck getting anything out of this "stone restorer".

It’s crazy bc it is a stone repair company. It’s not like I hired a random guy.

Live with, or replace, is your two options.

How much would you all think it would cost to replace? We have a large kitchen

Did he know they were engineered quartz not quartzite? I mean anyone can tell from photos but maybe they sent a newbie that had never seen estone?

He new it was engineered quartz

Knew

You have repeatedly mentioned stone. But these counters are Quartz, and you mentioned a "manufacturer". Quartz should not be sealed. That is one of the reasons people like Quartz. When Quartz is sealed the sealant is not absorbed, it just sits on top. That causes hazing and streaking (what your husband called "less shiny", and the fingerprints). But that is all moot, since the Quartz counters were initially damaged - slightly - by you. You probably could have just lived with that, but now the counters are truly damaged and should be replaced - on your dime - or you can just live with the marks they have now.

This is just so disheartening bc the owner of the company assured me quartz could be refinished with the right tools. I’m just in shock I have to replace my countertops

Maybe the warranty is affected. Even so, the people to get your information from are the product manufacturer tech support. They can tell the steps and product necessary to bring your surfaces back. Imo, they shouldn't need a sealer . The manufacturer may think something else. They should tell you what product to use. If no sealer is recommended, The surface can be stripped and polished. Again, the tech support guys can tell you the correct steps and products. They may also be able to recommend a contractor.

This was a stone repair company. Quartz is not stone, as the owner had to have known.

Agreed

Jessica:

What is the brand of your countertops please? Some brands, like Santamargahrita, are made with marble instead of quartz, which would explain your etching and scratching problem.

It is possible to refinish engineered stone; I've done it. Getting the scratches out is the easy part; matching the factory finish is not.

Had you hired me to refinish your tops, you would have acknowledged in writing that they were ruined and that I could only improve them or no Joe for you. When you gave me a poor review, I would post your disclaimer and note that I refunded all of your money. Apparently your refinisher is as technically challenged as are his business practices.

There should have been no noticeable swirl marks.
