Instant Install 29-8 oz Epoxy Permanent Repair Kit - Granite, Marble, Porcelain, Quartz, & Tile - Chips/Cracks - Rebonds/Rebuilds Missing Pieces - Dry in 29 Minutes - Tintable with EZ-Tint

Recently I found several chips where you come out of the shower/threshold and a friend found this for me and said let’s try this versus replacing a whole piece of granite. It worked amazingly well and has held up like a champ. You have to move fast as it dries fairly quickly and you can mix multiple color options as well. It is really amazing epoxy. You won’t be disappointed. I was expecting the worst but received the best!

I purchased this epoxy product back in April 2022 and again in Dec 2022. Worked great both times. Highly recommend! The first repair was to "clear" fill a crack in a marble floor where the slab under neath cracked. Next job was to filled travertine holes to keep dirt from accumulating. Note the cracks and holes must be completely free of dirt, oil, wax and water. The clear epoxy picks up the color of the marble and travertine and is almost invisible, matching the stone filler used by the factory. The Dec Job was to fill small chips 1/8" to 1/4" in a ceramic tile. The tile was a beige with brown/gray streaks. Since the chipped holes reveled the red/dark brow tile, the color needed to be matched. ordered the EZ-Tint 4 Pack color power pack recommended by the seller to mix with the epoxy. Unfortunately, I could not find a combination with these four color tints to match the tile. I went against the sellers recommendation no to use liquid tints. I bought a liquid tint specifically for epoxy gel coats ( Fasco Epoxies-Beige Pigment for Epoxy Resin, Gelcoat, Paint - 4 oz). To that I added Brown and Black EZ-Tint 4 Pack color power to get the shade I wanted. The critical thinag I learned by experimentation is the liquid color must be mixed into the "RED" Instant 29 material before mixing in the "Black" Instant 29 or the epoxy does not harden. Use only a small amount og liquid colorant to not screw up the epoxy. Note: any moisture, even high humidity prevents or inhibits epoxy from curing properly. I like to clean with MEK. Besides the razor for scraping excess, MEK can remove thin epoxy film in the first hour or two. Always work with small batches. Starts to gum/harden in about 15 minutes at 70F. Do not use gummy epoxy-it wont adhere and smooth properly. If you screw up use MEK to remove the epoxy before it cures. By the way MEK fumes are nasty. I suspect that those buyers who rated the product as poor may not have properly prepared the surface (i.e sand the underlying gel coat or fiberglass on their boat) or had too high of a moisture content on the part or in the air. While the manufacturer did not specify a minimum working temperature, I suggest you have the part you are repairing and air temperature above 60F. A lower temperature may not cause the necessary chemical reaction to harden the epoxy. Follow the instructions for best results.

Good product to repair granite. It was simpler concealing cracks, but patching a faucet hole in kitchen granite counter took several attempts to finally "match". I think I applied, scraped and reapplied 6-7 times before I was satisfied, so be prepared to experiment, it's easy to apply, harder to match. With the accompanying color packets, a little goes a long way. Use new razor blades, lots of them.

I'm surprised there are so many negative reviews - this stuff is insanely good. There were two giant chunks of countertop broken when I bought my house. The previous owner was a terrible DIYer, and used silicone to glue them back in. They were near the sink, and eventually lost their adhesion and worked their way loose. Now, I am also a DIYer, and have never even attempted anything like this before, but I at least do my due diligence enough to have found this product (and to know not to use silicone to repair granite!). You can see the before and after in my pics, and the after came out way better than even I could have hoped. Even in person it's barely noticeable, you have to really, really look. And part of the repair included building up a missing chunk, so you know this is pretty incredible stuff. Here are my tips.. Buy a bunch of small samples to test your countertop color, I just searched "Mica Powder for Epoxy Resin" and a ton of options came up. This set of 24 had the color "Black Sea" that matched my green countertop almost perfectly: https://www.amazon.com/gp/product/B0759DH4ZG. I bought a few others and just returned the ones that didn't look right in person - it's sometimes hard to tell from a screen. The nice thing is that these little packs go a long way - you really don't need a lot of pigment at all to get your color. I still have about 95% of the color packet left over after my repair. Use more than one color; I marbled mine with a black dye that I had on hand. Clean your working area thoroughly, I used TSP, and test fit the pieces before you install them. Seem obvious, but still needs to be said. Test test test. I can't stress this one enough. It will help you get color and the mixture right, and give you more confidence working with it. Because it hardens so quickly, it really doesn't add on much time to do a few tests to get your color and consistency right. And it will give you a feel for your timing. I used my Echo to set a 1 minute timer to mix, a 5 minute working time, and then another 5 minute second-half working timer as a sort of warning to myself - and I could feel it start to get harder towards the end to the point where it becomes unworkable. Then just clean up the excess, mask it up with Frog tape, and leave it for the remaining time. Don't let it over-dry! I did that the first time and it got too hard - it flaked off with the razor instead of easily peeling off, and it pulled out the repair from my crevices. I found just following their directions exactly produced the best results (go figure). And don't be afraid to mess up. I tested it out a few times on some smaller less noticeable areas of my sink and found the color wasn't right, or the repair had other issues. I worked those out in the smaller places before tackling the big repair. I ended up pulling some of those out, it's pretty forgiving stuff until it really cures. Also, it seems to work better on deeper cracks where it has something to bite into. Go slow and steady with the razor when you're done, and if you mess it up, it's fine. You can just rebuild. I had to rebuild the small missing gap a few times before I finally got it to where I was satisfied. I know it seems like all this testing takes forever, but trust me it doesn't. I was done in an hour or so, and couldn't be happier. The end result far exceeded any expectations I had going into this, but I followed the directions exactly, did my research, experimented, and took my time on the final repair. If I can do it, literally anyone can. This stuff works.

I bought this to fill a joint in granite that had come lose in front of my sink. The granite would actually deflect slightly, the adhesive underneath had come loose also. This stuff is by far the best epoxy I've ever used. I didn't spend a tremendous amount of time mixing the color from a kit I also bought on amazon, I just got it close and it is good enough for me. The directions are spot on. You have 15 minutes of working time and it seems like it immediately cures at that point. I mixed it up in a small plastic solo cup and right at 15 minutes while I was still holding the cup it suddenly became extremely hot. It began solidifying right after. Another 15 minutes later, it was like concrete. I poured a bunch of this under the gap between the granite and plywood (my sink was out for replacement) and when it cured it completely eliminates the deflection even with my putting all my weight on it (~225lb). This stuff is really easy to work with, and it is extremely strong. There is no more deflection in my countertop, the joint is now filled in again and seemless, and although not perfect, it looks really good and I'm very happy with it (and I'm very particular). I highly recommend this product, especially for granite joint repairs.

This product worked super! I had a granite kitchen countertop that was broken in to 4 pieces. The breaks were where the sink is, along the narrow sections in front and back of the sink opening. I have multiple areas of granite countertop in the kitchen, and to replace a section of granite for that one area would have been next to impossible to find to color match up to all the other countertop pieces! Otherwise, I would of had to replace all pieces in the kitchen...$10,000 or more. So fixing this was greatly desired! I've never done anything like this but I am somewhat handy and decided why not give this a try. Well, it was easy and worked great!!! problem solved for next to nothing cost wise. Took about an hour to get set up, do the job and clean up! I was maybe lucky in that all 4 of my pieces fit back together like puzzle pieces, so they glued up and matched up nicely. I glued it in place on top of the cabinets where it goes. Turned on the stop watch on my phone so I knew where I was with the 15 minute work time, mixed more than enough epoxy for the job, used shims for my sticks to spread the glue, placed more than enough epoxy on both sides of each piece where the joints matched up so when I clamped the 9' long section, it squeezed epoxy out the joints....but no need to get carried away with too much epoxy. As the directions said, once the epoxy was dry to the touch, I took a straight razor and simply bladed off the excess glue. My granite was mostly white with black and brown and colored speckles but I used no tint and it matched up perfect for color with no tint. Can hardly see where the breaks were. I am thrilled with this product!!! Can't say enough! Saved me literally thousands of dollars! Yes, it does have epoxy oder but it's epoxy! Didn't need a mask and what little oder there was, was gone in no time. Not sure what some of these review people are talking about with that??? Just lay out your job, have a plan and git er done! If I could I would give this product 10 star's! Thank you!

Tavertine stone in my shower holes appeared after the manufactured "fill ins" fall off. Stone starts to fall apart bit by bit if you don't use a sealer often. I thought this was good to try, but nope! I've worked with several epoxy consistencies. This "knife grade" is not any better than the regular 2 part clear epoxy mix. If you need to experiment with a little, home improvement stores sell them in a package with 2 syringes. 1) The epoxy drops, leaks, weeps, drools... if you have big holes or gaps to fill (~1/2 in. Circumference or more), you'll have to sit there and keep moving it back in place with a putty knife until it sets. Unless you can rip the tiles off your walls and have set level flat on the floor😆. Eventually it set enough to fill the hole, but you have to really set it at the exact 20 second window to do this. From mixing 30ml of the 2 parts, it took somewhere within 1.5-3 minutes. 2) after the 20 second moldability period is over, the rest of the product is worthless. It is already set in the container you have it mixed in. 3) sand surface before applying. You will most likely need to sand the epoxy after it dries. It will not be flush when applying on a wall or ceiling. 4) not for high moisture environments. Although I had sealed my travertine lightly before the epoxy and well after, the epoxy falls off after a few weeks of shower use. If your epoxy layer is about 1 cm or thinner, it will eventually bubble up and fall off. Peels off like a vinyl sheet against a wall. The deeper holes or thicker areas of epoxy fall off after a month. Grout was more efficient in my case.

When first opening the black colored epoxy component lid it appeared the product had prematurely dried. Although the black lid was tight and the two-part epoxy package was shrink-wrapped, the epoxy had dried out at approximately 20% of the material near the top of the container. Fortunately, I was able to puncture through the cured material to access the unharmed product below. On the other hand, the epoxy material in the red lid container had not dried out. The product worked great but I was unable to use 20% of the material purchased, and it was quite expensive.
