I'd like to know the answer because I have something very similar. It doesn't bother me all that much, but if there's an easy fix, I'd be very interested.

Could you share the model of your cooktop?

Thank you Grover! Jae, I’ll check my paperwork tomorrow and post!

For some reason Joe I can’t see ur comment even thought my email shows me half of it, I will keep refreshing and hopefully it shows up so I can read ur advice!! Thank you!

Jae... here is cooktop

The epoxy fill used for seam is a gray instead of a white. Would recommend they mix white with a hint of gray. This may match the stone a littler better. With that being said, you will always see the seam because it is a straight line running through material and not natural looking but color match will help.

It's normal to seam a long run of granite or Quartz at the narrowest visible spot (the edge of the sink or the edge of the cooktop. My seam was at the sin, but they put a matching colored mastic in the seam so it barely showed. Because your Quartz is white, the seam, even if filled with matching mastic or grout will need more attention because it is white. I would try using a little bleach on a q-tip once a week.

I'll repeat myself; maybe you can see this one:

It depends. If they used a clear adhesive, that often shows up as a medium gray which appears to be the case. If the seam is wide enough to remove the adhesive or enough of it, it can be done over with a better color match.

If you have a do-over done, I'd retard the adhesive catalyst. You'll have to pay more for the tech to wait longer for the adhesive to harden, but catalyst causes yellowing in whites. You don't want the seam to look great now, but turn yellow(ish) in a year or two.

If the joint is contaminated, I'd poultice it with some #40 peroxide from the beauty supply store.

These whites are notorious for color matching seams.

" I would try using a little bleach on a q-tip once a week."

Bleach is much too strong for engineered stone. Once or twice, maybe, but bleach every week will destroy this top.

Joseph, thanks. I still can’t see ur earlier post.......what was your advice? It’s very valuable to me! If I lived near you I’d already have made an appointment! Charleston is a tad too far!!!

Thanks, I see both posts now lol! I was hoping you’d say I could use magic something or other. I may try the peroxide if the builder argues with me.
