Construction & Operation
Construction Conditions
- 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.
- 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%.
- Ventilation conditions: Ventilation should be maintained during construction.
Operation Methods and Requirements
- Select materials.
- 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.
- 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.
- After mixing evenly, spray once in both directions.
Suggested Use Qty
Single square meter dosage ≥1.3kg
Frequently Asked Questions (FAQ)
What are the main characteristics of this product?
This product cures at room temperature, exhibits excellent physical and chemical properties, provides strong adhesion, and offers highly efficient construction where a single application can meet the design thickness requirements.
What is the recommended storage condition for the coatings?
The coatings should be stored in sealed containers under dry, cool, and well-ventilated conditions. It is essential to avoid direct sunlight and rain, and keep the product away from any sources of fire.
What concrete base surface conditions are required before construction?
The concrete base surface must be cleaned, repaired flat, and polished to a certain roughness. The concrete curing must be fully completed with a strength reaching C25 or above, and the moisture content must be less than 8%.
What are the environmental temperature and humidity limits for application?
Construction should only be carried out when the environmental temperature at the site is above 5 ℃ and the relative humidity is strictly less than 85%. Adequate ventilation must also be maintained.
What is the suggested single square meter dosage and mixing ratio?
The suggested single square meter dosage is ≥1.3kg. The recommended ratio is: ≥0.9 kg glue, 1 ~ 1.1 kg of 0.5-2mm size granules, 0.3 ~ 0.4 kg rubber powder, and 0.06 kg color paste.
How do you handle viscosity issues during winter construction?
When temperatures are low in winter, viscosity issues can be resolved by heating the glue to ensure proper covering and bonding strength. If necessary, a suitable amount of environmental protection diluent can be added to adjust viscosity, but it should not be made too thin.
