Thank you for enjoying the video! Glad you were able to learn from the video. For terrazzo floors, divider strips are placed on the floor to provide form and function. Divider strips can come in a variety of materials - aluminum, brass, zinc and even plastic. They are flexible to be bent by the installer on site. Aluminum is cost-effective and easier to grind onto. Brass on the other hand is harder to grind. Aluminum and zinc are similar, zinc tends to shine. They are capable of creating any shape. Even a waterjet can cut metals into intricate patterns and designs for logos or complex artwork. The divider strips are placed according to the design, and glued down. The terrazzo colors are then troweled between the divider strips.

@@Terrazzco Thank you for the quick response! I have a few more questions regarding the dividing strips. You mentioned that plastic can also be used. Since I have a 3D printer, I could create custom shapes with it. Could you tell me which type of plastic would be best for this purpose? Additionally, I’m planning to lay Terrazzo flooring in a 12-square-meter room. What would the mix ratio be for this area, and what materials do I need? Thank you in advance for your help, and I look forward to your response!

@@Rachid-q2e Regarding plastic strips, tthe dividers are cast from resin. They can range in color from clear, white, black or custom colors. Manufacturers also supply a plastic strip (Manhattan American and National Metal Strips are supplier members of the NTMA). Epoxy terrazzo is a 5:1 ratio, which includes a two-part epoxy resin and aggregates. Other materials may be needed including a moisture mitigation system, crack suppression membrane, leveling fill, primer (depending on which epoxy resin system you use), etc. Given the complexity of the process and the specialized equipment required, it is recommended that epoxy terrazzo installations be carried out by qualified contractors.

Thank you so much for your kind words! We're glad you found the information helpful. Our website www.terrazzco.com is a good resource to learn more about terrazzo. You may also check out our association NTMA at NTMA.com as well for more case studies and technical guidance.

Divider strips are manufactured by either Manhattan American Terrazzo Strip Co. from Staley, NC, which is seen in the video, or by National Metal Shapes in Delaware, OH

In the terrazzo industry, there are many terrazzo systems that can be installed including cement and epoxy terrazzo, each has its own technique. These are performed on a job site. There is also precast terrazzo, which is manufactured within a company's facility and the products and then delivered to a job site for contractors to install. The demand for terrazzo craftsman is projected to increase as more terrazzo is being installed. Terrazzo installers are required to travel across the US. There are terrazzo installation companies in nearly every state. Larger states like New York, California, and Florida have multiple terrazzo companies. In terms of job experience, an individual can take on an apprenticeship or on-the-job training to learn the terrazzo process. A person with masonry skills can find a good career in terrazzo.

It is advised not to use wax on terrazzo floors. Its tends to create buildup and dull the finish of the terrazzo floor. For terrazzo floors using TERRAZZCO products, we recommend a water-based acrylic sealer (ex. Betco Sure Cure/Untouchable)

Depending on where you are located. If you are looking for a qualified terrazzo installer, you can check out the National Terrazzo and Mosaic Association website for listings in your region. Contractors can then contact Concord Terrazzo Company for materials as needed.

Glad to hear! Thanks for taking the time to have a watch

Thanks for sharing!

I too worked in a building from about that era, and when I initially started working there, construction was going on in the building and the terrazzo floor in the lobby looked like it in horrible shape, and would need to be replaced, which I thought was a shame. At the end of construction, the floors were polished and they looked like new. I was always curious about the fabrication & installation process, and what made the material so durable; and this video did a great job explaining it.

We use a spectrophotometer. You can see the machine in use here: terrazzco.com/creating-color-match/

@@Terrazzco hi do you have ready mix products for this slap on this video.

You are welcome. If you have any questions about terrazzo, I'd be happy to help.

You are welcome. Glad we could help you learn more about terrazzzo.

TERRCO has modern models for terrazzo grinders. The one used in this video is an older version. Once epoxy terrazzo is poured, it will cure before the grinding process. This takes approximately 24 hours. Grinder is pushed along a path 4-5 times. Edges can be ground using an edge grinder along places like walls, columns or other areas where a machine cannot reach.

Epoxy terrazzo can be tinted in any color. I'll create a video displaying more possible color options for terrazzo base and flooring in the future. Thanks for the comment!

Thank you, glad you found the video informative

Appreciate the feedback. Terrazzo is a versatile product that can be used for different designs applications today. Epoxy terrazzo is only recommended for indoor settings. To design a terrazzo table for outdoors, cement terrazzo is the ideal application.

Its acceptable to use either a poured in place or terrazzo tile system for bathrooms and kitchen spaces. Epoxy terrazzo is nonporous and far more water resistant than cement terrazzo. Due to its nonporous properties, a seamless epoxy terrazzo is not only water resistant, but also stain and bacteria resistant. Whereas seamless terrazzo is poured over most substrates, tile will require a setting material during installation, and include the grout lines. Grout lines are one of the major differences between a seamless terrazzo system and a terrazzo tile system. The grout lines increases the overall maintenance of the flooring system and is common place for dirt and bacteria to hide. Poured in place terrazzo is a smooth seamless system where simple sweeping and mopping routine will clean the terrazzo floor.

Would you recommend terrazzo to be manufactured into bowls for eating? If so, should cement terrazzo or epoxy terrazzo be used? Does the porous nature of cement terrazzo have any implication for food use?

We have distributors in India, but not in Pakistan at the moment. If you are looking for materials, our sales representatives can further advise you at info@terrazzco.com

Yes training would include subfloor prep. SUBSTRATE PREPARATION FOR TERRAZZO Course Objectives and Description: Demonstrate knowledge and skills in substrate preparation by visually inspecting the substrate, explaining or performing substrate cleaning, installing anti-fracture materials, patching defects, installing expansion and control joints, preparing a sound surface, and explaining the installations of waterproofing membranes. Hours: 30 Due to the current events, we have paused training classes for flooring contractors for the time being.

For epoxy terrazzo installations, tools and equipment is cleaned using isopropyl alcohol or mineral spirits before epoxy begins to harden.

Yes. We can direct you to one of our partners in India who can supply the materials needed upcoming projects in your area. Please contact Impact Floors at ceo@impactfloors.co.in and discuss their terrazzo solutions using TERRAZZCO Brand materials.

Thanks for your interest. Currently we've suspended our training courses to flooring contractors since the pandemic. However, you may be able to find some training opportunities through the National Terrazzo and Mosaic Association (NTMA). There are also apprenticeship programs as well with the Union of Bricklayers and Allied Craftworkers.

@@Terrazzco I did not find anything about terrazzo training, please let me know if you do the training again

@@Terrazzco gooday, please what are the materials used in the base based terrazzo floorings.

Hi Omar. Concord Terrazzo Company manufacturers epoxy terrazzo slabs. But to answer your question regarding cement terrazzo, The marble chips and/or aggregates are mixed with the binder at a ratio of 2 to 1 (Chips to Binder.) Most specifications will recommend a mix of one bag of portland cement (94 pounds) per 200 pounds of aggregates. During the flooring installation of terrazzo, additional chips may be sprinkled on the surface so that a minimum density of 70% marble chips appears on the finished surface.

@@Terrazzco thank u 🙏🏻😊

@@mekka_awy You are welcome. Glad I could help you

@@Terrazzco hi I want to build this slab but different size can I order the read mix ?

Hello. We use a spectrometer to match colors for the terrazzo. This video on our UA-cam channel can show you how colors for epoxy is determined. Hope this helps: ua-cam.com/video/yY5MpBkJzIA/v-deo.html

Another similar video, this one taking a paint deck and then creating epoxy color for a terrazzo floor. Hope this helps: ua-cam.com/video/k1DozD5MVRc/v-deo.html

Hello we are are a US terrazzo manufacturer and terrazzo. If you wish to inquire more about epoxy terrazzo, please contact our representatives at info@terrazzco.com to further assist you.

Poured in Place Epoxy Terrazzo: It's a 5:1 ratio of Part A Epoxy Resin to Part B Hardener, add 180 pounds of specified aggregates (marble, glass, shell chips) and 50-pound of AFT-20 filler powder. These ingredients are mixed together thoroughly, and placed over a subfloor, troweled at either 1/4" or 3/8" thickness. Hope that helps!

@@Terrazzcodefinitely it's helpful, thanks! But how about the ratio of epoxy to other ingredients! I mean how much of epoxy do i need if i put 180 pounds of aggregates and 50 pounds of the filler?!

@@desigerz7364 For epoxy terrazzo, for one volume of epoxy resin, there will be 3 volume of marble aggregates. Epoxy resin is mixed per the manufacturer's recommendations. Our TERRAZZCO epoxy resin comes is packaged in a Part A resin at 5 gallon pails or 55 gallon drums, and Part B in one gallon cans or 5 gallon pails. (By volume, 5 parts of Part A resin is mixed with 1 part part B hardener). Coverage per mixed gallon for 3/8" thickness is 9-10 square ft and coverage per mixed gallon for 1/4" thciness is 11-12 sq ft. A terrazzo floor has minimum 70% chip density.

@@Terrazzco Thank you so much. Wish the best for you.
