Tenax Tixo Knife Grade Polyester Resin - 1 Quart

I used this to fabricate a shower niche surround out of 3/4” marble and it worked wonderfully. I used my Kerdi Shower nich as a mold and lined it with wax paper then built my marble frame with this Tenax mastice and once cured, removed it, removed the wax paper and used epoxy mortar to glue the unit in the shower niche. This is nice material and very strong. It cures in 15-20 minutes.

Easy to blend in color for perfect match. A few drops of activator (use just a little) and you’re ready to apply. Hardens quickly and is hard as a rock when cured. Strong bond.

I had a recent misfortune with a purveyor, and could not get knife grade poly epoxy. This is required for making seams, joints, laminate edges, miter edges, waterfalls, basically, it is the heart and soul of a stone companies successfulness. I had a client break, a floating shelf, the material that was on the shelf was a very exotic Cristallo quartzite. It contains numerous colors and lines, that would make hiding the damaged area easily, except Cristallo is a quartzite that is also 100% transparent. It is used primarily in applications where it is either under lit or back lit by LED lights. Even the most costly epoxy company, boast transparency in the product, but commonly once a Cristallo has broken, no amount of care will ever allow the epoxy to be transparent as well. Once the item is lit, where the epoxy attached the broken piece, no light will shine through. The table in the photo was in three pieces. I will not say anything else about the product other than I would like you to look at the photograph posted and tell me where the three sections are. This epoxy, dried transparent, and I have never seen that before, even from the most expensive manufactures like K Bond, Apoxsee, and they are $199 each. I used the tinting kit, the epoxy in its natural state, has a golden hue. It immediately transforms to any pigment colors. I used several colors, all premixed, without the hardener. As I layered it in, I wanted to save the strikingly white inner inclusions, and maintain the golden highlights, as I said, it was broken into 3 sections. Clean through. It was harder polishing the areas back to a shine, and it did so fine.

It doesn't cure 100% clear like I wished it would but it's still a good product.

Works great on a quarts slab

I do marble repair professionally and quite frankly, this product is a huge disappointment. What came in the can was a rubbery, glob of yellow goo. It mixed poorly with the hardener and was difficult and stiff to work with. The stark yellow color made it impossible to mix good color matches with it. It does harden, but it's awful to work with. The fumes it gives off are terrible and unhealthy to work with and my clients won't appreciate that in their buildings. I certainly don't want to give them cancer.

Great product with great color ability. Use with acrylic color kits. This polyester has a long working time. Sometimes this is better. Tenax also makes a acrylic product that is faster. Sometimes that is better. I keep both in supply. I do granite countertops and have always been very happy with Tenax products

I use this to fix broken pieces of granite. It sets up really hard and it is fast enough that I don't have to build braces.
