Your fabricaator has abraded through the Nano Ink. There is no getting it back. Your edges are mitered, but instead of just knocking the meanness off the miter, he profiled the edge, exposing the tile underneath the printing.

I wonder what I am supposed to do now. They are insisting I pay for the countertops minus the installation. They only put one small area piece on top of plywood in my new build house. It is not permanently installed.

Tell them you're not accepting the product and they need to remove the existing piece. You'll inspect any future attempts at their shop before installation. Start talking to alternative fabricators. These guys probably aren't going to be able to perform.

I could not possibly take seriously any manufacturer that says their products 𝘵𝘢𝘴𝘵𝘦 just like other makers quartz.

And they tell you right off, it 𝐢𝐬𝐧’𝐭 quartz. And that the pattern is printed, just like tile.

If you want quartz, you want a different material.

I would have your HC handle this,  as that's what you pay them for.   Insist on not paying for this product.  I can't see how any reasonable person would accept those white edges.  I also can't see how any shop would think those edges are acceptable.  It's this their first time working with this product?  It's only surface printed so you shouldn't sand off the printing at all.

You are also going to have an issue with the overhang after the end panel goes on that cabinet. End panels should be applied before templating. Or your designer/GC/responsible party/you needs to be there and indicate that an additional 3/4” will be added. Then review their measurements before they leave the template, AND after the template is laid on the stone. That presumes your designer/GC/responsible party/you own their own tape measure and understands counter measures.

I definitely will have to check the problem of the end panel out. My GC says not to pay for the countertop charge.

I am so so appreciative that people are willing to give advise on Houzz and other pages. Thank you

I hadn't seen this product before. I have to assume the main benefit is price?

What happens when you drop something heavy that chips the counters? Will you be seeing the white base? Can it be fixed?

Is this the "budget" version of porcelain slabs, but without the benefits of a slab porcelain material? How does this material withstand hot items placed on the surface?

It wasn’t as cheap as granite. I paid 6500 for 4 slabs. It is made by Symphony. I had no idea the color does not run all the way through. I was told it is quartz.

I read that even the color was sanded off, there was no fixing it.

I haven’t seen this product either but I will be on the lookout to avoid! No body would want this! How would it be finished at a sink?

Funny you should ask. My pattern for my Kohler sink was asked for. You would think they would advise me before cutting out the sink hole that be because my so called square but slightly rounded corners could not be mitered with color surrounding my black sink. I would have a big white band around my black sink. Once again, with no proof, the owner lied and said I was shown it and told it. Where is the video of it? Everything is recorded! They asked for the template a few days before install and I was on a trip so how could I be shown it?

Where did you view and purchase the product? Hopefully your gc will go to bat for you.

Both at Monterey Tile, the slab store, and at Desert Sky Surfaces where they have a sample display. One of the owners said she was going to take the display down as this is an inferior product. Yet, she expects me to pay money for it. Maybe they do not want to admit their employees should not have sanded the color off.

They were trying to treat it like quartz, where the pattern goes all the way through, rather than porcelain, where the pattern is only printed on the top surface. The rounded over edges were to keep them from being chipped or from being a sharp cut you open hazard. That rounding was a good thing, and entirely commendable and logical, IF the material had a pattern all the way through.

The trouble comes in via the fact that the pattern is only printed on the surface. Maybe their distributor touted this new stone without telling them that. Or the right person wasn’t there when the distributors salesperson called. Or they just didn’t listen, or read the specs.

Why it ended up that way is unimportant, except to them. That’s their business issue to solve.

How they are going to learn from this mistake, and handle this mistake is the issue that affects you. They know it is not an acceptable result, so give them a graceful out with a blame target. ”Im sorry your distributor didn't tell you the pattern was on the surface only. New materials always have a learning curve. For everyone involved. You would not accept this result for your home, or your showroom, would you?“ Stare at them. In person. Say nothing. See what they offer.

The distributor should offer to replace the slabs for you with another brand of actual quartz that they carry. Get a list of the brands they carry. They should offer to swallow the labor. It is their price for being educated about the material.

On the bright side, they did do a nice pattern match along the long edge.

The owner told me she was taking the sample display out of her showroom. It sounded to me like they have not worked with Symphony before. I did feel for them as we like to support small businesses just as my husband and I have.

At first she was very nice showing me different materials to choose from and I thanked her for her time she spent with me. I would not want to lose so much money either. I did suggest that we could use it in a different way maybe on our outdoor patio where it is not so critical and I have a more rustic theme out there.
She said it can’t have direct sunlight on it and I told her that we have a covered patio not direct sunlight, no more sunlight than through a kitchen window.

With all the subs throwing away material into the huge dumpster in our front yard, I am concerned how much goes in our landfills. I would think she would say ok and let’s see how it can be recut at our expense and get some new material at our cost to install in your kitchen. Nope!!

She keeps sending me the invoice of two kitchens. Even after I told her that they would have to compromise.

No concessions.

Do not let them finish the installation of the kitchen or do anything in the kitchen, except remove all that product.

Your contractor needs to get involved, if he was part of the process to begin with.

Take lots of photos before they remove any materials. You might need it in court.

"They only put one small area piece on top of plywood in my new build house."

I can't imagine roof sheathing being a manufacturer-approved underlayment for this product. Should probably be Wedi board. They couldn't get the edges right; unsurprising that the proper underlayment would stump them.

You should not offer to compromise. You should choose a completely different source for a fresh start with a different product.
