Just did a comparison between Akemi Nano Effect and Miracle Porous Plus on Absolute black flamed granite tile: Both sealers are excellent against water (it beads up). Two coats of Akemi and even a single coat protect against water, espresso, wine, and olive oil (right). Porous Plus (right) darkens the stone a bit more (this is 24 hours after application), and resists all but the oil well. The negative control of untreated is down the center. Conditions left to right: 0.5 mL of distilled deionzed water, hot espresso, red wine, and olive oil. Top 1/4 (two coats of sealant applied 4 hours apart), top middle quarter (single coat), bottom half (two coats, applied immediately after one another with 5 minutes to soak, then wipe). Have some Tenax Proseal coming tomorrow to compare to Akemi, the clear winner here.

I know it’s been a while since you posted. Could you share what product you used fir sealing. Thank you!

Neither Uba Tuba or Tropic Brown granites need any sealing at all. They are both very dense granites. Don’t seal them. If you seal them, it might mar their appearance. Very dense granites like those two won’t absorb sealant, so the sealant ends up sitting on the surface causing a hazy appearance. You’ll also get streaking if you drag something like a plate on the counter because the sealant is sitting on top not absorbed, and you streak it by dragging something along it. https://www.absolutegranitestl.com/natural-stone-maintenance/sealing-granite-demystified/
