Bonstone Natural Stone Repair Kit

This product is good and easy to use. I had a large piece of Marble that had gotten broke and it is like new..

Nice product. Easy to use. Good instructions. It created a rubbery filling that filed a couple of edge chips well. Would not look good in big holes. Comes with black, white and tan tint.

I filled a chip in a black countertop about the size of a dime and about a millimeter deep. I masked around the chip and followed the instructions. Once complete, the patch feels no better than having a piece of black electrical tape over the chip. Could easily pull out. Instructions say to now grind and polish, which I have not done since I don't have the equipment and also fear scratching the surrounding area, even if I mask it. I highly doubt the patch would stay in place while being polished. I also tried to fill another smaller chip, and the patch did not stick at all. It just pulled right out when I removed the masking tape the next day. Maybe the patches would somehow hold if polished and then the entire countertop were coated with a polish/chemical. But don't expect a professional job or for it to look like there was never a chip.

Purchased the kit without reading the other review and it was a mistake. I have to agree withe other negative feed backers that the product description is actually misleading. The product is easy to use bit this product will not harden enough to achieve the needed hardness to facilitate an edge repair( chips etc) It stays rubbery and can be pulled out by simply rubbing it. I'd rather get the epoxy and be done with it for good. Amazon was super and refunded the purchase promptly

Did the job.

Worked well

My first attempt to use this product to fill minor chips on the edge of a black granite kitchen countertop was a flop. The goo oozed all over the place, and needed to be completely scraped off after it dried. I'm going to try it again, this time using a removable tape edging to hold the goo in place while it dries. I'll update my report if this expedient works. But I expect I'll still have to figure out whether to use an Xacto knife or a very fine emery cloth to smooth things over if it works.

Not a lot of choices to choose from, however this product did the job and I didn't require a master degree in granite countertop fixing.
