Hi. Is anyone familiar with this terrazzo product:
https://duracryl.com/wp-content/uploads/Durabella-Specsheet-2021.2.pdf
Curious about fire, stain resistance, abrasion resistance, and other criteria compared to other resinous terrazzo systems.
Thank you. |

Ken, did you ever use this product? I know it's been a couple months. We are using it on a large hospital project in California. Our designers vetted it, selected it, I specified it, the contractor bought it, and now we are getting grief from an outside relative of the owner, who says he knows flooring, that it is not a true epoxy terrazzo and it may fail if not properly installed. Duralcryl is not a member of NTMA so they can't help. Not sure if I trust the owner's brother for feedback on flooring products, but.... Still, I am curious if you ever had it installed or if you ever received any feedback about the product other than what's on the website. Or if anyone else knows anything about it. |

I had a project where the architects liked it, but we have no experienced installers in the Northeast, so the Owner said no thank you.
I think every flooring might fail if installed incorrectly.

Duracryl is saying Apple and Disney have used it extensively in California to success but only time will tell. It is not epoxy, it is a "biopolymer" and is also "Red-List Free" if that is a requirement. The corporate office is in the Netherlands. |

I'll ask.
A few questions I raised to the manufacturer that never were answered (well I didn't see any responses):
1. No indication of what it's made from. Bio-based?. What is the material? From the name I'm presuming it is some form of acrylic but have no idea what it is or how it is bio-based.
2. Test reports are needed. This is an unknown product. We require independent testing.
3. Chemical resistance: Most values similar to epoxy but no value given for the following:
a. Sulfuric acid @30%?
4. Stain resistance: We know about what to expect from epoxy terrazzo systems but this is bio-based.
a. Curious as to how it stands up to typical items like coffee, mustard, cola, ketchup, other food items that can end up on the floor as well as personal-use items like lipstick, shoe polish, etc. Test reports would be helpful.
5. Note epoxy vs. Duracryl values:
a. Shore D Hardness: 60 to 85 vs. 50 to 60
b. Tensile Strength: 3000 PSI vs. 1,500 PSI
c. Compressive Strength: 10,000 PSI vs,. 5,000 PSI
6. Duracryl sealer says something about R-11. I understand that this is an EU slip-resistance value but have no idea what the US equivalent is.
7. Their Guide Spec wording is unacceptable (the exclusions listed are not acceptable for our Work).
a. We don’t care who does MVE or other protections. It’s part of the Work. They need to provide us with pH and alkalinity limits, acceptable MVE products/treatments, etc.
b. Crack suppression: Need to know what acceptable products are. If not by Duracryl, what products are approved for use? Crack suppression is required over entire substrate, not just at cracks.
c. Slab repairs materials: If no one knows what Duracryl is how can they select compatible products. Duracryl needs to provide a list of acceptable repair materials/products.
d. How do these treatments affect their claims for sound reduction? Need test reports for sound reduction claims. |
