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 stir fully and 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, resulting in insufficient slurry packaging on the granule surface.
- d After mixing evenly, spray once in both directions.

Frequently Asked Questions (FAQ)
Q
What is the curing method of this polyurethane PU binder?
A
This PU binder cures at room temperature. The surface drying time is 6–12 hours at 25℃, and full solidification is achieved within 24–48 hours under the same conditions, making it convenient for efficient on-site construction.
Q
What are the typical application scenarios for this PU binder?
A
This product is widely applicable to floors, color sand floors, marble floors, and road surface color changes. It is also suitable for laboratories, pharmaceutical factories, parking lots, subway stations, supermarkets, warehouses, and heavy-load industrial plants.
Q
What are the environmental requirements for construction?
A
Construction should be carried out when the environmental temperature is above 5℃ and the relative humidity is less than 85%. Good ventilation must be maintained throughout the construction process to ensure safe and effective application.
Q
What are the base surface requirements before applying the PU binder?
A
The concrete base surface must be cleaned, repaired flat, and polished to a certain roughness. The concrete curing must be completed, with strength reaching C25 or above and a moisture content of less than 8%. The next construction process should begin as soon as possible after base surface preparation.
Q
How should this PU binder be stored?
A
The product should be stored in sealed containers in a dry, cool, and well-ventilated environment. It must be kept away from direct sunlight, rain, and any sources of fire to maintain product quality and safety.
Q
What is the recommended dosage and mixing ratio for this PU binder?
A
The recommended single square meter dosage is ≥ 1.3 kg. For the mixing ratio, use ≥ 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 per square meter. Ensure all components are thoroughly mixed before spraying in both directions.
