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 stir the glue and color paste fully and evenly, then add granules and red rubber powder and stir fully and evenly. Combined with site conditions, an appropriate amount of eco-friendly diluent may be added to adjust construction viscosity — do not adjust too thin, to prevent the material from penetrating into the particles and excessive atomization when spraying, which results in insufficient slurry coating on granule surfaces.
- d. After mixing evenly, spray once in both directions.
Suggested Use Quantity
Single square meter dosage ≥ 1.3 kg
