I agree Ron- a combination of both issues.
I have seen this happen and can understand why the owner is freaking out.
Too late to tell him sealers or any chemical should be tested for result prior to using.
Did that wall really need to be sealed?
I know -a whole other debate but a great question nonetheless.
The product used to protect the surface failed on day one.
If you look at the msds sheet you will see it is mostly mineral spirits with a small amount of acetaldehyde which am not sure may be the resin.
I think it is important to read these msds's to see what your working with. Test to make sure.
Sorry to say but I think a bad choice of product for a wall.
An aqueous fluorochemical may have been a better choice after testing.

I would agree but mu understanding from the initial email it was stated the panel changed after they were sealed. That’s why I think it’s a seal issue.

I don't believe it was a sealer  because the color difference I consistent on the whole panels. I think that the panels were all different sheds to begin. Just like you see with the floor tiles that even they the same stone there is a variation in color. the only way to get consistent shade is to get the panels from the same slab or block in the quarry. That's the beauty of nature, If he wants them consistent he should order something man maid so it has the same color, or paint what's on the wall. I don't think there is other solution then painting or he will have to learn how to leave with it.

Ron,

 

You going to need to remove the sealer that was applied. This is what is causing the different colors. The limestone is more porous on some areas and the sealer is darkening the limestone. . be careful removing the sealer that you don’t get water stains in the limestone.. when removing or cleaning the sealer out ,start from the bottom up. If you work you way from the top down you will have a high risk of streaks in the stone. check with Aqua Mix to see what chemical you need to remove their sealer.

 

Before committing to the job, TEST, TEST and TEST again.

Partners,

My client has an owner who has extremely high standards. They have installed these very expensive wall panels and the owner wants them 100% consistent. He doesn't want any variation from panel to panel. The limestone has been sealed with Aqua Mix Pro, and now we can see very distinct differences in shades. I've explained natural stone to him.........He wants us to deliver one shade. Throughout. It can be darker.  Suggestions?  Pictures Attached.

Ron
