Granite Repair Kit (White) I Suitable for Most Repairs I Also for Tile, Porcelain, Countertop, Fiberglass & Ceramic Surfaces I Fix Broken Chips & Cracks in Minutes

This product is a life saver. I chipped my white (with tiny grey specks) countertop on the edge that leads into the sink. The chip was kind of deep. I was moving out of this apartment. and this repair from a repair man would have been hundreds of dollars; I don't even want to know how much the apartment complex could have charged me for damaging this very large, continuous slab of quartz countertop. I kind of followed the included instructions of this product to perform the repair. As I was sanding the finished repair, the repaired spot popped loose! I was definitely frustrated. Then I read the FULL product repair instructions, and followed them exactly... If you have a deeper nick or repair, you need to apply and cure the product in stages or layers. This allows the under layers to cure and adhere to the surface properly. The finished result was a flawless and solid repair on the edge of my quartz counter. And you could almost not tell at all that it was even repaired... it blends that well. The only reason you could tell a little bit that it was a small spot repaired is because the counter is white with light grey specks in it... and the repair material is just white. But it was so barely noticeable, it was even a challenge to locate the repaired spot without having to stair a the counter and really look for it. This is a great product to repair counters and keep them look pristine, smooth, and perfect... and a product that is durable. I couldn't find this product or anything like it at Home Depot or Lowe's. I only found it on Amazon. Great Product!

I was excited to purchase and use this product based on the positive reviews. The steps seemed easy to follow and as an extra, I watched a YouTube video to make sure what I was going to do was correct.The curing process with the blue light was awful. My hands were hurting because there wasn't a button to hold the light down. What I ended up doing was unscrewing the light and taping it down to ensure the light stayed on. Despite this, the curing process took over 24 hours!When the curing process was finally done, I sanded it following the directions on the box. This either removed completely some material in the hairline crack or made some of the cured material darker. Now the hairline crack and sink look worse than it did before I used this product.Thinking the final step, Polisher Paste, would make it "shiny" or enlighten the darkened material, it did not. At this point, it would be easier to replace the sink all together, especially now that it looks so much worse than it did when I had the hairline crack.I'm really unhappy with this product. I do not recommend.

Follow the instructions and this product works as advertised. It didn't 100% match my white ceramic sink, but it's close and you would have to know that it was repaired to detect it at all. I have previously used less expensive solutions and none of them worked very well. I am hopeful that this is a long term fix.

We had a huge crack on our bathroom sink, this product pretty much did its job and sealed the cracks as if it never happened!

Easy to use. Disappointed in white matching. It is not as white as Kohler white.

Bought this to fill in a hairline crack in a $2,000 sink, worked perfect!

It does not dry. I now have to remove it …

A working repair kit that does its job well. We are thankful for this purchase!

Good product, easy to use but it is not really white

For a long crack, this product is useless unfortunately. Left the blue light shining on the repair for 24 hours and it still didn't cure. Don't waste your money or time.Update: Seller kindly followed up and issued a refund. It appears there is an issue with some of the batches where the incorrect product is inside the tubes. Seller stands behind the product.

Simple, good but expensive
