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, fully stir the glue and color paste evenly, then add granules and red rubber powder and stir fully. Combined with the site situation, an appropriate amount of eco-friendly 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 less slurry packaging on the granule surface and future granule loss.
- d After mixing evenly, spray once in both directions.
Suggested Use Quantity
📐 Single square meter dosage: ≥ 1.3 kg
Frequently Asked Questions (FAQ)
Q
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. Under standard conditions (25℃), the surface drying time is 6–12 hours and full solidification is achieved within 24–48 hours.
Q
What types of flooring surfaces is this PU binder suitable for?
It is suitable for a wide range of surfaces including standard floors, color sand floors, marble floors, and road surface color-change applications. It is widely used in laboratories, pharmaceutical factories, parking lots, subway stations, supermarkets, warehouses, and heavy-load industrial plants.
Q
What are the base surface requirements before applying the PU binder?
The concrete base surface must be clean, flat, and polished to an adequate roughness. Concrete curing must be complete, with strength reaching at least C25 and moisture content below 8%. The next construction process should begin as soon as possible after surface preparation.
Q
What are the environmental conditions required for 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 optimal curing performance.
Q
How should the PU binder be stored properly?
Store in sealed containers in a dry, cool, and well-ventilated environment. Keep away from direct sunlight, rain, and any sources of ignition. Proper storage ensures product quality and extends shelf life.
Q
What is the recommended dosage and mixing ratio for application?
The recommended single square meter dosage is ≥ 1.3 kg in total. The suggested mixing 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. In cold weather, gently heat the glue to reduce viscosity before mixing. After thorough mixing, spray evenly in two perpendicular directions.
