Precautions
The drying effect of water-based coating products is greatly affected by different environmental factors. During application, a comprehensive judgment should be made based on the temperature, humidity, wind speed, and drying conditions of the environment, to achieve the best appearance and performance of the paint film.
The self- recoating interval must be at least 1 hour after the surface dries, and the actual time depends on the impact of different environmental humidity and temperature on product drying; General between 2 hours and 6 hours; It is best to reapply the topcoat with an interval of more than 24 hours.
The operation temperature is between 10℃ and 30℃, and the operation humidity is no more than 75%. It must be thoroughly stirred and evenly mixed before use, and frequent stirring is required during coating, to prevent sedimentation.
