The prevailing climatic conditions during blasting and painting are critical in achieving a successful coating application.
Dewpoint
Controlling climatic conditions is a critical part of blasting and coating inspection. Environmental factors such as air temperature, surface temperature, relative humidity and dew point directly influence the performance of abrasives during blasting and the long-term quality of protective coatings. When these conditions are not properly monitored, moisture can condense on the substrate, leading to flash rust after blasting or coating defects during the curing process.
To prevent moisture-related issues, it is essential to accurately measure and monitor climatic conditions before, during and after abrasive blasting and painting operations. By measuring the air temperature, relative humidity and surface temperature, the dew point temperature can be determined. To avoid condensation on the surface, the substrate temperature must remain at least 3°C above the dew point.
Inspection equipment for climatic conditions supports quality control across blasting processes, ensures compliance with coating specifications, and helps achieve reliable adhesion and durability of coatings in industrial surface preparation.
Temperature
The temperature must always be monitored to ensure that it remains within the parameters of the coating specifications. The curing process can fail if the temperature is too low or too high.
