Epoxy grinding stone: a new type of floor decoration material that combines performance and aesthetics

In the field of modern architectural decoration, epoxy grinding stones are gradually replacing traditional flooring materials with their excellent comprehensive performance and high artistic expression, becoming the preferred choice for high-end commercial spaces, public facilities, and boutique residences. It is made with epoxy resin as the core adhesive, combined with natural or artificial aggregates through multiple fine processes, achieving a perfect unity of practical function and aesthetic value.

1、 Product Core Definition and Classification

Epoxy grinding stone, also known as gold grinding stone or artistic grinding stone, is a new type of flooring material formed through a specific process by scientifically grading epoxy resin, special pigments, curing agents, quartz sand, colored glass particles, natural shells and other aggregates. Unlike traditional terrazzo, which uses cement as a binder, the introduction of epoxy resin fundamentally improves material performance and endows it with richer decorative possibilities. According to the differences in construction methods, there are mainly two types:

① Cast in place epoxy grinding stone: Directly laying, pouring, and forming materials on the construction site can achieve a large-scale seamless effect, especially suitable for the landing of complex patterns and personalized designs. It is the core choice for creating an overall aesthetic in commercial spaces.

② Prefabricated epoxy grinding stone: It is made into sheet or block products in advance according to specifications and design requirements in the factory, and then transported to the site for splicing and installation. The construction period is relatively short, suitable for projects with high standardization.

2、 Core performance characteristics: comprehensive advantages from practicality to environmental protection

The performance advantage of epoxy grinding stone comes from the polymer properties of epoxy resin and scientific material ratios. Its various indicators meet the strict requirements of modern buildings for floor materials, which are reflected in the following aspects:

1. Excellent physical performance and durability

As an ideal material for high-frequency usage scenarios, its mechanical strength is particularly outstanding. Surface hardness can reach 8H, Mohs hardness level 7, compressive strength ≥ 25MPa (some high-end products can reach 60MPa), flexural strength ≥ 20MPa, able to easily withstand forklift crushing, pedestrian impact and other tests. Excellent wear resistance, with an extremely low wear rate of 750g/500r, and minimal scratches caused by daily friction. The service life can reach over 20 years, and some projects can even achieve the same lifespan as buildings. At the same time, the elastic properties of epoxy resin effectively alleviate temperature stress, reducing the risk of cracking by more than 80% compared to traditional terrazzo, and solving the pain point of easy damage to traditional floors.

2. Environmental protection, safety, and worry free health

Adopting a solvent-free formula design, the solid content of the material is ≥ 96%, and the VOC content strictly meets the environmental standards of GB/T33372 and GB50325. The construction process has minimal pollution, no irritating odor, and can be directly put into use after completion. Recyclable materials such as recycled transparent glass and ceramic particles are often used as aggregates, which conforms to the concept of sustainable development. The dense and pore free structure on the surface can prevent the growth of bacteria and mold, and can meet the hygiene requirements of clean places such as hospital operating rooms and food processing areas after professional testing.

3. Easy to clean and maintain, with controllable usage costs

The seamless floor created by the cast-in-place process avoids the problem of dirt and grime accumulation in the gaps. Daily cleaning only requires wiping with water or simple mopping, without the need for regular waxing or crystallization treatment. The surface porosity approaches zero, the water absorption rate is only 0.03%, and the anti permeability performance is excellent. Liquid spills such as coffee, oil stains, laboratory reagents, etc. will not penetrate and can be directly wiped away. Strong chemical corrosion resistance, able to resist common chemicals such as acid, alkali, salt, gasoline, etc., with minimal maintenance and significantly lower long-term usage costs compared to traditional flooring materials.

4. Highly decorative, with high design freedom

This is one of the most competitive advantages of epoxy grinding stone. Through the mixing of colorants, thousands of color combinations can be achieved, with clear glossiness grading (high gloss ≥ 90GU, semi matte 30-60GU, matte ≤ 30GU). When combined with different aggregates such as colored glass, metal particles, shells, etc., it can create dazzling luster or warm texture. The flexibility of pattern design is extremely high, allowing customization of complex shapes such as wavy lines, logos, 3D effects, and even achieving integrated wall and floor design. For example, the circular floor of Changsha Science and Technology Museum seamlessly connects with the wall, while the swirling floor of Sephora Concept Store conveys a high-end texture. The brightness can reach 120+, the colors are bright and long-lasting, and the UV protective pigment can ensure a fading degree of ≤ 80% within 5 years, maintaining a beautiful state for a long time.

5. Safe adaptation, wide scene compatibility

Balancing smooth texture and anti slip performance, with a high dry friction coefficient and an anti slip value of ≥ 50, the anti slip level can be adjusted according to the scene. For example, anti slip aggregates can be added to the poolside and bathroom to effectively reduce the risk of falling. Strong adaptability to construction environment, construction can be carried out under the conditions of base concrete strength ≥ C25, moisture content ≤ 8%, ambient temperature ≥ 15 ℃ and humidity ≤ 80%. Through special process adjustment, it can also adapt to special requirements such as explosion-proof and anti-static. For example, copper grid strips are prohibited in explosion-proof areas to prevent static sparks, and the resistance value of anti-static flooring can be controlled within ≤ 1 × 10 ^ 6 Ω.

3、 Typical application scenarios

With its diverse advantages, the application of epoxy grinding stone has covered multiple fields such as commercial, public, residential, industrial, etc. Typical scenarios include:

1. Commercial space: luxury flagship stores, high-end shopping malls (such as Nanjing Deji Square), star rated hotels, branded restaurants (such as Starbucks Select), art exhibition halls, etc., enhance the spatial grade through customized design;

2. Public facilities: airports, high-speed railway stations, science and technology museums, museums, schools, hospitals (such as Xi'an Deyi Skin Hospital), etc., to meet the core needs of wear resistance, easy cleaning, and environmental protection;

3. Residential and boutique spaces: villas, open kitchens, art floors, high-end bookstores (such as Zhongshan Gou Bookstore), etc., to achieve personalized aesthetic expression;

4. Special scenarios: underground garages, laboratories, food processing areas, explosion-proof workshops, etc., suitable for special requirements such as anti slip, anti-corrosion, anti-static, etc.

4、 Core Tips for Selection and Construction

1. Material selection: Prioritize solvent-free products and confirm that VOC content, compressive strength, and other indicators meet national standards. The quality of aggregates directly affects the decorative effect and wear resistance;

2. Construction team: This material has extremely high requirements for construction technology and needs to go through 18 processes including base treatment, setting out and positioning, bottom coating, pouring, and multiple grinding and polishing (50-3000 mesh grinding discs),;

3. Acceptance criteria: The main control project must ensure that the VOC content of the material and the flatness of the base layer (excellent level ≤ 3mm) are 100% qualified. For general projects, attention should be paid to gloss deviation, grid joint straightness, etc., and the pass rate must be ≥ 80%;

4. Cost considerations: The initial unit price is higher than traditional terrazzo (about 500-1200 yuan/㎡), but due to its long service life and low maintenance costs, it has a better cost-effectiveness throughout its entire lifecycle.

Epoxy grinding stone is not only a decorative material for floors, but also an important carrier for connecting functionality and aesthetics in modern architecture. From commercial landmarks to home spaces, it breaks traditional limitations with material innovation, providing practical and artistic ground solutions for various scenes.
