I am not an expert but that doesn't look good. Here is my Minuet seam close up and far away. I am happy with my seam. Mine is also in a corner.

The experts on here should be able to tell you whether it can be repaired or needs to be replaced. I know LG has jumbo slabs as well.

It looks to me the adhesive is not color matched to the quartz but I am no expert in this. There are a lot of expert in this forum can chime in. Mine is pure white quartz and I got it through Ikea so I couldn't pick the fabricator. The seam is barely noticeable, pic below.

Mayflowers has a very nice seam and her fabricator used a special tools which my fabricator didn't used.

Here's another topic regarding quartz seams and you can see mayflowers seams toward the end of it.

need opinion regarding seam in my caesar stone

If you take a coin and run it back & forth over the seam is it a smooth run? The seam looks pretty bad. I would not be happy. Did you see any other their seams before?

I would not accept this -- it will just get worse.

That looks terrible. There is no reason you would be happy with it.

There are quite a few threads on GW working on this same problem.

They do look terrible - don't accept them. I'd withhold payment until they are repaired, even if it means getting a different fabricator for the repair.

Thanks everyone. I am meeting with the representative from the countertop place tomorrow and your comments were very helpful. I am going to bring some of the photos for reference.

How big is your island? The jumbo slab of viatera is 63x130. Why a seam right dead center?

That seam is unacceptable. Have them remove the island and if they don't have access to a CNC machine to dress those edges, they need to dress them by hand with a Seam Phantom. Major methacrylate adhesive manufacturers (Glue Warehouse, Integra) have color matched adhesive recommendations that have been tested, unlike color-blind Bubba with his polyester mix.

Everything I'm stating is industry standard. Tell your builder I said so.

Your builder needs to quit having his carpenter attempt to fab stone. I've seen that shortcut on too many jobsites.

I'll be interested to hear the size of the island, whether a seam was needed there at all. It all sounds like a real eyesore - in a very expensive kitchen investment.

Whose house and money is this? He will not do it for a price?

As far as the poor quality of the seam goes, the high prices we pay have the cost of potential errors and fixes built in as cover. Of course, the more mistakes that need to be fixed, the less of that cushion gets to be pocketed as profit. On top of that they have insurance.

Your builder states those seams are "standard." If he doesn't fix them (and his installer may not have the ability to fix them) you could contact Viatera and ask them if this is their "standard" seam appearance. You might also ask them for the name of another Viatera fabricator in your area.

Good point. Check to see if this fabricator is trained and authorized to work with their products. I don't know if it is SOP but many of these solid surface companies do operate that way.

You know the main thing I take from this, and so many other threads on GW -- I will NEVER work with a "spec" builder. It's true, it's my money, and I want it done my way or not at all.
