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 by 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, can not 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.
