Packing
📦 200 kgs / Drum
Storage
⚠️ Sealed storage of coatings in dry, cool, and well-ventilated conditions, avoiding sunlight and rain, and keeping away from sources of fire.
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 granule 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 covering and bond strength. First, fully stir the glue and color paste evenly, then add granules and red rubber powder and stir evenly. Combined with the site situation, an appropriate amount of eco-friendly diluent may be added to adjust the construction viscosity — do not adjust too thin, to prevent material from penetrating into the particles and excessive atomization when spraying, resulting in reduced surface slurry on granules in future.
- d. After mixing evenly, spray once in both directions.
Suggested Use Quantity
📐 Single square meter dosage ≥ 1.3 kg

Q
What are the typical application areas for this PU binder?
This product is widely applicable to floors, color sand floors, marble floors, and road surface color changes. It is also suitable for use 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 cleaned, repaired flat, and polished to a certain roughness. The concrete strength should reach C25 or above, and the moisture content must be less than 8%. Proceed to the next process as soon as possible after surface preparation.
Q
What environmental conditions are required during construction?
The construction site temperature should be above 5℃, and the relative humidity must be less than 85%. Adequate ventilation must be maintained throughout the entire construction process.
Q
How should the PU binder be stored properly?
Store in sealed containers under dry, cool, and well-ventilated conditions. Avoid exposure to direct sunlight and rain. Keep the product away from all sources of fire to ensure safety and product integrity.
Q
What is the recommended dosage and mixing ratio for this product?
