Construction Conditions
- 1 Base surface requirements: The concrete base surface should be cleaned, repaired flat, and polished to a certain roughness. Ensure that the concrete curing is completed, the strength reaches C25 or above, and the moisture content is less than 8%. After processing the base surface, the next process should be carried out as soon as possible.
- 2 Environmental temperature and humidity requirements: The environmental temperature at the construction site should be above 5℃, and construction can only be carried out when the relative humidity is less than 85%.
- 3 Ventilation conditions: Ventilation should be maintained during construction.
Operation Methods and Requirements
- a Select materials.
- b Recommended ratio of single square dosage: ≥ 0.9 kg glue, 1 ~ 1.1 kg 0.5–2mm size granules, 0.3 ~ 0.4 kg rubber powder, 0.06 kg color paste.
- c The granules size is recommended at 0.5–2mm. When the glue temperature is low in winter, the viscosity problem is solved by heating the glue to ensure the covering and bond strength. First, the glue and color paste should be fully stirred evenly, and then add granules and red rubber powder and fully stir evenly. Combined with the site situation, an appropriate amount of environmental protection diluent can be added to adjust the construction viscosity — do not adjust too thin, to prevent the material from penetrating into the particles and excessive atomization when spraying, which results in the granules surface having less slurry packaging and causing future granule issues.
- d After mixing evenly, spray once in both directions.

Frequently Asked Questions
Q1
What is the curing method of this polyurethane PU binder?
This PU binder cures at room temperature without the need for any special heating equipment, making it highly convenient for on-site construction. The surface drying time is 6–12 hours, and full solidification is achieved within 24–48 hours at 25℃.
Q2
What are the main application scenarios for this PU binder?
This product is suitable for a wide range of flooring applications including color sand floors, marble floors, and road surface color change projects. It is widely used in laboratories, pharmaceutical factories, parking lots, subway stations, supermarkets, warehouses, and heavy-load industrial plants.
Q3
What are the base surface requirements before application?
The concrete base must be cleaned, repaired, and polished to a suitable roughness. The concrete should be fully cured with a strength of C25 or above and a moisture content below 8%. The next construction process should begin as soon as possible after surface preparation.
Q4
What are the environmental conditions required during construction?
Construction should only proceed when the ambient temperature is above 5℃ and the relative humidity is below 85%. Adequate ventilation must be maintained throughout the construction process to ensure safety and product performance.
Q5
How should this PU binder be stored?
The product should be stored sealed in a dry, cool, and well-ventilated environment. It must be kept away from direct sunlight, rain, and any sources of fire or ignition to maintain its quality and safety.
Q6
What is the recommended dosage and mixing ratio for the PU binder?
The recommended single square meter dosage is ≥ 1.3 kg total. The suggested ratio is: ≥ 0.9 kg glue, 1–1.1 kg of 0.5–2mm EPDM granules, 0.3–0.4 kg rubber powder, and 0.06 kg color paste. Mix the glue and color paste first, then add granules and rubber powder. A small amount of eco-friendly diluent may be added to adjust viscosity, but avoid over-thinning.
