Storage conditions

1.The storage temperature should be 5-35ºC.
2.Under normal storage and transportation conditions, the storage period is not less than 6 months from the date of production.
3.Store in a cool, ventilated environment, avoid direct sunlight, prohibit close to fire sources, and prevent collisions.

Precautions

1.The pre-coated concrete substrate needs to be completely clean, If there are obvious damage to the interface and cracks, it needs to be repaired in advance. Before using the product, make sure to air-grind the surface or use vacuum to remove dust on the surface.

2.Can be used at a low temperature of -10°C. If used in a low temperature environment, please put the paint bucket in an air-conditioned room for >24 hours.

3.Ensure that the raw materials are accurately mixed and evenly mixed, use and pour out how much, and quickly close the lid of the bucket. The used paint must not be poured back into the original bucket. The poured paint must be used up within 1 hour.

4.The paint viscosity adjusted according to the needs of the product before leaving the factory. The construction personnel cannot continue to add the thinner without permission. If needs adjusted as the viscosity changes due to environmental or temperature reasons, call the supplier and add it after obtaining guidance & approval.

Product features
