Epoxy resin colored sand system

This system is a new type of seamless decorative floor composed of colored quartz sand and epoxy resin. Through the free combination of one or more different colors of colored sand, it forms a rich and colorful decorative effect. It not only has a decorative function, but also has more ideal wear resistance, pressure resistance, anti-slip, waterproof and chemical corrosion resistance properties than ordinary epoxy floors.

Product Details

Product features

  • The surface is smooth and clean, with bright colors and excellent decorative effect.

  • Good mechanical strength, anti-slip and waterproof;

  • Wear-resistant, pressure-resistant, impact-resistant, and has good chemical resistance.

  • It can be made into a smooth or rough surface as required and has an outstanding anti-slip function


Scope of application

It is mainly applicable to floor scenarios that require high strength, high mechanical performance, good appearance and wear resistance, such as large shopping malls, exhibition halls, subways, electronic communication, medical and health care, airports and other places. It can also be used in high-end entertainment venues, business buildings, exhibition centers, large shopping malls, offices and other places with higher requirements.

Notes

  • When spreading colored sand, the surface must be flat and attention should be paid to the uniformity of the colored sand spreading.

  • During the construction process, a dedicated person must repeatedly check the flatness of the paving surface with a straightedge. Special personnel should be assigned to handle the elevation at the skirting boards and corners to ensure the overall flatness of the ground.

  • Construction conditions and base material preparation should be strictly carried out in accordance with the product manual.


Technical Statement

Our company can design construction plans of different specifications (thickness, effect, etc.) through flexible matching and combination of various products to meet the personalized requirements of all kinds of customers. To ensure that your project can select the appropriate floor system, please consult our professional technical advisors. However, when using our company's products, please strictly follow the construction process, dosage requirements and precautions of the product. Otherwise, our company will not bear any responsibility for the quality of the project or any losses.


Construction Process
Process NameSpecific Methods and RequirementsSingle Coat Usage (kg/m²)
Substrate Treatment1. Substrate strength: Not less than C20
2. Substrate flatness: ≤3mm (measured with a 2m ruler)
3. Substrate dryness: Moisture content of substrate surface < 8%
4. Repair hollowing and cracks on the ground in advance
5. Fully grind the concrete substrate
6. Level the skirting lines and corner areas		/
Primer Layer1. Use WEDO-1102: Mix base paint and curing agent in proportion until uniform
2. Apply evenly by roller coating or knife coating
3. Ensure no whitening or missing application areas		0.3–0.4
Sand Pressing Layer (Bonding Layer)1. Apply the bonding layer before sand pressing: Use WEDO-1102, apply evenly by roller or knife coating to cover the entire floor
2. Use WEDO-1102: Mix base paint and curing agent in proportion, then add colored sand at the recommended ratio (Paint:Colored sand = 1: 10–16); use a vertical mixer for uniform stirring
3. Spread the mixed colored sand evenly on the bonding layer as required, level with a straightedge to control flatness; press corner areas manually with force
4. Level and press with a troweling machine, and control flatness		1.0–1.5
Grouting Layer1. Use WEDO-1102: Mix base paint and curing agent in proportion until uniform
2. Pour evenly with a knife to ensure overall uniform grouting		0.5–2
Topcoat LayerUse WEDO-0704/WEDO-0704S: Mix materials in proportion, fully emulsify, then apply evenly by roller coating; ensure uniform layers with no material accumulation or missing application areas0.1

Construction conditions

  • Air temperature: 5℃ - 30℃

  • Relative humidity < 80%

  • The moisture content of the substrate surface is less than 8%

  • The construction site should have good ventilation

  • Dew point temperature: The substrate and the substrate of the uncured coating must be at least 3℃ higher than the dew point temperature to reduce the risk of condensation or mottling of the ground coating. Oily floors must be thoroughly cleaned up; otherwise, it may affect the even application of the coating.
