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. Review: I used dry powdered dye for concrete to match the color to fix a long crack that was forming in my granite. Dye costs about $5 at a home improvement store. Used two plastic spoons - one for each container - to get equal proportions. Mixed epoxy is a bit stiff but I was able to force it down and it did settle a bit into the crack. The first batch was not dyed and it looked shiny to me. I then dyed the next batch and it is perfect. I let it set for 30 minutes and then razored off the excess proud to the surface. ## Features - Any & All Countertops - Ceramic, corian, formica, granite, marble, porcelain, quartz, quartzite, silestone, slate, soapstone, tile, travertine, wood. - Easily Tintable - Seamlessly match stone colors with EZ-Tint pigments.

You could lightly sand the dried epoxy and paint it though. Thank you for your question, Epox-Sci **Q: can this be used on chips on the edge of a granite counter top?** A: Hello, Yes. If you have the chip, simply mix and apply epoxy to stone and clamp or tape the chip in place firmly until epoxy is dry, then razor off the dried excess. If you do not have the missing piece, you can "create" it using the epoxy. It may take a little practice. You will need to first tint the epoxy with our EZ Tint (sold separately) as close to the stone color as possible. Then, depending on the size of the missing piece, you may need to add un-sanded grout to give the filler more body to ensure that is does not sag. Shape into place and allow to dry. If your first attempt is not as satisfactory as you would like, allow it to dry-to-touch, then dig it out and repeat until you are satisfied with your results. If you razor the surface of the finished piece, the surface will be more of a matte finish. You can apply something like a dab of acrylic polyurethane on the surface with a small artist's brush to restore gloss finish. If you leave the surface undisturbed, it will naturally dry to more of a glossy finish. Thanks for your question, Epox-Sci **Q: Will this work for a quarter size chunk missing from my granite fireplace hearth?** A: Yes it will, you may have to apply twice due to size of chunk missing but it will work **Q: Can it be mixed with stone dust for colorant?** A: Hello, You can certainly try that or you can use our EZ Tint (sold separately). I'm not sure I've heard of someone using stone dust, but it sounds interesting. Please let me know if it works if you do. Almost any type colorant is compatible. Thanks for your question, Epox-Sci ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***H on 1 January 2023* I purchased this epoxy product back in April 2022 and again in Dec 2022. Worked great both times.

It was thick enough that it didn’t drip through the seam and instead had to be pushed into. During removal of our granite, we had chipped a large piece off at the seam (shown in pictures). We were very happy with how this product filled both the seam and allowed us to reattach the chipped piece of granite. However, we did also have a small hairline crack of which we applied the product and did not get the intended result there. Once dried, we scraped with a razor and all of the product came out of the hairline crack. Overall, I’m happy with the larger seam and countertop repair so I’m giving the product 4 stars. Please check out the pictures to see how it turned out. Some observations: it hardens pretty fast. The longer you wait, the tougher it might be to scrape off. Make sure you’re using a new razor. And if you’re using this on countertops, consider trimming with painters tape. For our larger seam, this made the scraping process so much easier. ## Frequently Bought Together - Instant Install 29 – 8 Ounce Epoxy Permanent Repair Kit – Granite, Marble, Porcelain, Quartz, & Tile – Chips/Cracks – Re-Bonds/Rebuilds Missing Pieces – Dry in 29 Minutes – Tint-Able with EZ-Tint - EZ-Tint 5-Pack - 10 Grams Each of Black, Brown, Green, White, and Yellow - Highly-Concentrated, Finely-Ground Pigment Powders for Tinting Instant Install 29 and All Other Epoxies/Polyesters - 4 Inch Diamond Polishing Pads with 5/8’’-11 Backer Pad, 12PCS Wet/Dry Granite Stone Polish Pad Kit for Drill, Grinder, Polisher, 50-6000 Grit Polishing Pad for Concrete Marble Rock Countertop Quartz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/326592338-epox-scis-instant-install-29-8-oz-knife-grade-epoxy](https://www.desertcart.co.za/products/326592338-epox-scis-instant-install-29-8-oz-knife-grade-epoxy) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-24*
