Application of Paint Systems All paint systems must be applied according to the respective Technical Data Sheets F379 / F393 Etch primers may require an induction period prior to application. Please refer to TDS. F379 / F393 Etch Primers must be applied to a dry film thickness of 15-25 microns 7-53X Selemix Direct must be applied to a minimum dry film thickness of 80 microns.
Painting should not be carried out at temperatures below 5°C, or if the temperature is likely to drop below 5°C during the drying time of the paint
Painting should not be carried out if the Relative Humidity is above 80%.
The dew point should be tested prior to painting. The substrate temperature should be at least 3°C above the dew point. This is to avoid condensation forming.
Record the temperature, Relative Humidity and Dew Point at the time of painting.
