It took me a while to get around to finding all of the dings on my granite counter top but a rainy weekend motivated me to clean off the counter and find all of my gouges. The instructions for this product are simple and clear, with both good written and pictorial directions. I cleaned the counter and then wiped each area with isopropyl alcohol. My initial plan was to try and use a razor blade to skim off the top of the epoxy once cured, which is NOT part of the instructions. However, I found that this ended up popping the repair out of the gouge as well, causing me to have to redo some of the repairs. instead, I used the razor to cut the overflow AWAY from all around the repair. It left the repair intact and gave me far less to sand and polish. I skipped the large grit sandpaper lest it scratch my counter too much and just used the 2500 grit and the polishing compound. The end result is as good as, probably even better I could have hoped for; The smaller blemishes are completely invisible to the eye and can't even be felt when rubbing a finger over them. The largest divot is still visible through the clear epoxy (but only if you know where to look for it) but when I run my finger over it I can no longer feel any depression or edge there. I would call it a definite success, and it took me longer to clean and mask the area than it did to do the repairs (minus the 5 minute UV cure).Some tips:-Practice with the syringe on a piece of paper towel, as it is stiff and you risk splooging epoxy all over your counter if you don't have a good feel for it.-For small dings, consider using a toothpick to harvest a little off the end of the syringe. the less you use, the less you have to sand.-The "tape" isn't adhesive, it's a plastic film. Don't waste time trying to peel the non-existent backing off! LOL-Instructions say to use the stick or your finger to "level" the epoxy under the tape. Don't use your finger, use the side of the stick, or even better, a piece of plastic with a straight edge, like a ruler. I used my finger and it pushed into the dents, forcing epoxy out, causing me to have to redo a couple of spots.-I used a clothespin to set the UV light up pointed at the repair. Saved me having to stand there holding it for 5 minutes per spot.If you have a quartz countertop that has some "signs of use", I would DEFINITELY recommend this product. I'm not sure how it will wear, but I'll certainly keep an eye on it and I'll update my review should I encounter anything that warrants it.

Buon prodotto specifico per il quarzo.

I fixed a marble benchtop and a marble table. The product did seem to take longer than 5 minutes but has done an amazing job.Follow the instructions carefully.

Did not work as described. I tried 4 times following the instructions exactly. It did not harden and stuck to the plastic. I tried it with both lights and still didn't harden. Quite dissatisfied. I tossed it out. Cost was too little to bother returning to Amazon.

Easy to follow instructions. Fixed a .5 inch deep chip on a marble dining table and you can’t even tell. It’s been a year and held up! 10/10 recommend

Worked ok but I expected it to go harder than it did and although I left the the light on it for the 5 mins as stated it kept coming out of the chip so I left it for 10 mins and it seemed to be better but not as good as they make it out to beconsidering there are cheaper ones on the market I would have thought it would be better quality I would not be buying this again
