Cementious terrazzo VS epoxy terrazzo

Date:Apr 02, 2021

Many customers will have a question: What is the difference between cementious terrazzo and epoxy terrazzo?

Is cementious terrazzo or epoxy terrazzo better? Which one is more suitable for our design?

Let's answer them one by one below.

1. What are epoxy terrazzo and cementious terrazzo?

The concept of epoxy terrazzo and cementious terrazzo

The earliest concept of terrazzo is water terrazzo, which is also a kind of cementious terrazzo. It has a history of more than 100 years. Later, with the development of cementious materials and epoxy materials, especially the breakthroughs in materials and processes in recent years, cementious terrazzo and epoxy terrazzo materials classified by material properties were introduced.

The new concept of terrazzo is made by mixing gravel, glass, quartz and other aggregates with different materials (cementious or epoxy) binders to make concrete products, and then surface grinding treatment by professional machinery and professionals. Sealed, solidified, polished and finished products.

Here comes the point:

cementious terrazzo: The terrazzo made of cement, glass or other cementious binders is called cementious terrazzo (such as cementious terrazzo, glass-based terrazzo, etc.).

Epoxy terrazzo: The terrazzo made with epoxy, polyurethane or acrylic adhesives is called epoxy terrazzo (such as epoxy terrazzo, polyurethane terrazzo, acrylic terrazzo, etc.).

We now only compare the latest and most popular epoxy terrazzo and cementious terrazzo (new cementious self-leveling terrazzo). Other terrazzo can be used as a supplement to these two types of terrazzo, especially functionalized special terrazzo.

Both epoxy terrazzo and cementious terrazzo have the following characteristics:

The whole is seamless, easy to clean, non-toxic and environmentally friendly, wear-resistant, impact-resistant, water-resistant, and durable. Moreover, because of its mosaic pattern, the color can be spliced arbitrarily, the artistic appreciation and practicality of terrazzo have been perfectly combined. The patterns can be combined at will, the colors are colorful, the surface is smooth and delicate, highlighting the dignity and dignity, has become a designer and owner The first commercial floor material, especially suitable for the ground decoration of large shopping malls, mid-to-high-end commercial buildings, luxury clubs, exhibition halls, hotels, residences and villas.

1. Construction technology

It is recommended that whether it is epoxy terrazzo or cementious terrazzo, a leveling layer is required to prevent the risk of terrazzo cracking due to cracking of the base layer.

Epoxy terrazzo construction process:

Grassroots treatment: sanding, repairing the grassroots, cleaning and drying;

Primer: Epoxy primer roller brush once

Surface coating: mix the epoxy terrazzo base material with colored stones, glass and other aggregates, pave and screed; after curing, use a special machine to polish and polish several times;

Floor thickness: 6~10mm

cementious terrazzo construction process:

Grassroots treatment: wash planing or shot blasting the grassroots, clean and dry;

Primer: Apply the interface treatment agent twice

Surface coating: Special cementious self-leveling materials are mixed with colored stones, glass, etc. to pave, scrape, and deflate; after curing, use special machinery to smooth and polish several times;

Floor thickness: 10-15mm

2. Difficulty of construction

Epoxy terrazzo floor: more complicated

cementious terrazzo floor: a little simpler than epoxy terrazzo

3. Make pattern attributes

Epoxy terrazzo floor: slightly stronger

cementious terrazzo floor: slightly worse

4. Color decoration

Epoxy terrazzo floor: The color is brighter, but there will be a slight yellowing over time, which affects the aesthetics, especially in light and non-light areas, there will be more obvious color differences after a long time.

cementious terrazzo floor: Will not turn yellow, and the color will not change after decades.

5. Scratch resistance

Epoxy terrazzo floor: poor

cementious terrazzo floor: very good

6. Mohs hardness

Epoxy terrazzo floor: 5-6

cementious terrazzo floor: 7+

7. Price comparison

Epoxy terrazzo floor: relatively expensive

cementious terrazzo floor: moderate

8. Gloss

Epoxy terrazzo floor: 80+

cementious terrazzo floor: 80+

9. Clarity

Epoxy terrazzo floor: about 95

cementious terrazzo floor: around 95

10. Construction period

Epoxy terrazzo floor: long

cementious terrazzo floor: short

11. Fire and flame retardancy

Epoxy terrazzo floor: the fire rating can only reach B level

cementious terrazzo floor: the fire rating can reach A1

12. Environmental performance

Epoxy terrazzo floor: a small amount of VOC is released, which is a material controlled by the state

cementious terrazzo floor: zero VOC, low-carbon, environmentally friendly and energy-saving material

13. Construction safety

Epoxy terrazzo floor: unsafe, easy to catch fire

cementious terrazzo floor: It is safe to cure the product with water.

14. Service life

Epoxy terrazzo floor: generally 15-20 years

cementious terrazzo floor: the same life span as the base

15. Future development trend

For the future development trend, my opinion:

Epoxy terrazzo floor: Improve scratch resistance by improving the toughness of epoxy-based materials. It can also use polyurethane and acrylic materials as terrazzo to achieve some performance requirements that epoxy terrazzo cannot meet (such as acid resistance, alkali resistance, Chemical resistance, etc.). At the same time, a solvent-free epoxy terrazzo system can be developed to reduce VOC content and truly environmentally friendly products.

cementious terrazzo floor: Due to the complexity of cementious materials, the control of material quality is the key to the quality of the final product. Due to the popularity of nanomaterials, cementious terrazzo materials have greater development potential.

16. Problems to be solved

Whether it is epoxy terrazzo or cementious terrazzo, it has been gradually recognized by customers because of its irreplaceable characteristics. However, because there is no national standard at this stage, the product performance is very different, which limits the popularization of products. It is recommended to establish corresponding standards as soon as possible To standardize products to prevent fake and inferior products from damaging the reputation of products and affecting the long-term development of products.
