QUESTIONMy Glass Tile Changed Color. How can I adjust the color back? - I had a glass tile kitchen backsplash installed and the installers used a white grout. The glass tile was pale aqua, pale blue, pale grey..like water ripples, now it is dark teal, dark blue and dark grey and the white grout is the first thing that you notice. I have search everywhere for a grout colorant that will restore the color and characteristics of the tile. I just tried adding acrylic turqoise from Ben Franklin to Aqua Mix Buff and applied it on a test piece of tile. It looks very subtle with the tile and the tile colors have returned to their original state I'm wondering if it is ok to go ahead and do this with the whole backsplash. The backsplash has no sealer on it and I talked with Aqua Mix and they said they didn't recommend it but couldn't give me a reason why.
ANSWERANSWER - Normally it is due to the color of the thin-set adhesive that affects the color of the glass tile. I suppose the grout color can to, but generally speaking white grout doesn't distract from the color and is the color you normally want to use.
If you have tested this out and verified that if you change the grout color you will get the look that you want then go for it. No manufacturer is going to approve of you to alter their product. They have no way of knowing if your alteration will be a problem or not, so if you do it then it is experimental and at your own risk. Aqua Mix in the past would match most any color, so you can ask if they will match the color you want. Good Luck.
