stain/poulitice problem on granite

[Defusco Industrial Supply]

Philo,
When the newly polished edge is lighter than the polished surface it is usually because the stone has been resined for strength or beauty. For those instances a color enhancer will work fine on a polished edge. It is the experience of my customers and myself that black absolute doesn't take to color enhancers. If the stone is getting lighter it could be a couple of reasons:
If it is basalt and has a high calcium content it could be etched and will appear gray.
If it was a dark gray stone that was dyed black and not resined and the color is removed with a poultice or acetone it will appear gray.
The Uniblack 1 & 2 was made for this problem "Absolute Black". It is NOT granite, even though it is sold as granite. It is usually basalt.

Aloha!

Jo, I think this discussion should be taken in to the trades forum.

These are very good discussions on enhancers, dyes and, resined stone, but maybe a little confusing for the consumer.

Defusco, thank you for the confirmation of altered 'absolut black' and the basalt issue. I have come across jobs that are exactly what you've stated. I would like to hear more about your suggestion for the restoration of black galaxy too.

Philo, i have not heard a review about the Akemi super darkener yet. How would you compare this product to Ager or Ager Tiger?

Thanks,

Glenn K
