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 fully stir evenly, and then add granules and red rubber powder fully stir evenly, combined with the site situation can be appropriate to add an appropriate amount of environmental protection diluent to adjust the construction viscosity. Cannot be adjusted too thin, to prevent the material from penetrating into the particles and excessive atomization when spraying, the granules surface of the slurry packaging less resulting in future granules.
- d After mixing evenly, spray once in both directions.
Suggested Use Qty

Frequently Asked Questions (FAQ)
Q1
What is the curing time for this polyurethane PU binder at room temperature?
At 25℃, the surface drying time is 6–12 hours, and full solidification is achieved within 24–48 hours. The operation window is 60–90 minutes, giving applicators sufficient working time before the material sets.
Q2
What types of surfaces and venues is this PU binder suitable for?
This binder is suitable for a wide range of applications including color sand floors, marble floors, road surface color changes, laboratories, pharmaceutical factories, parking lots, subway stations, supermarkets, warehouses, and heavy-load industrial plants.
Q3
What are the base surface requirements before applying the PU binder?
The concrete base surface must be cleaned, repaired, and polished to an adequate roughness. Concrete curing must be complete, strength should reach C25 or above, and the moisture content must be below 8%. Proceed to the next step as soon as possible after surface preparation.
Q4
What environmental conditions are required during construction?
The ambient temperature at the construction site must be above 5℃ and relative humidity below 85%. Adequate ventilation must be maintained throughout the entire application process.
Q5
How should the PU binder be stored to maintain its quality?
Store the product in a sealed container in a dry, cool, and well-ventilated environment. Avoid direct sunlight, rain exposure, and keep away from all sources of ignition or open flame.
Q6
What is the recommended mixing ratio and application dosage?
For each square meter, use ≥ 0.9 kg of glue, 1–1.1 kg of 0.5–2mm EPDM granules, 0.3–0.4 kg of rubber powder, and 0.06 kg of color paste. The total single square meter dosage should be ≥ 1.3 kg. Mix glue and color paste thoroughly first, then add granules and rubber powder and stir evenly before application.
