In order to avoid defects due to the formation of condensate, a thermometer (to measure the air temperature), a hygrometer (to measure the relative humidity) and a contact thermometer (to measure the surface temperature of the substrate to be coated) should be available on-site. These measuring devices should be robust and accurate. They can be obtained through opticians and laboratory supply stores.  \nThe dew point is checked as follows:  \n1. Establish contact between the contact thermometer and the substrate to be coated. If necessary, with the specific version of the thermometer at hand, wait 15 minutes before taking the reading, giving the thermometer sufficient time to show the actual temperature of the substrate.  \n2. Read off the air temperature of the thermometer for measuring the air temperature.  \n3. Read off the relative humidity of the hygrometer.  \n4. From the below table, read off the dew point temperature of the table at the intersection of your measured air temperature and your measured relative humidity.  \n5. Read off the surface temperature of the contact thermometer.  \nIf this temperature is at least 3 °C above the dew point temperature taken from the below table and if the air and object temperature is above +5 °C, then the work can be carried out safely. If the temperature of the substrate (measured with the contact thermometer) lies close to the dew point or below it, then no coating work should be carried out because the danger of condensate forming is high. Recheck your condition site regularly. Pay attention to adverse or changing weather conditions.  \nTable for determining the dew point  \n\n| Air temperature + °C | 40%\u003Cbr>Dew point Temperature in °C at a relative humidity of\u003Cbr>50%  60%  70%  80%\u003Cbr>90% |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- |\n| 30 | 14.9 | 18.4 | 21.4 | 23.9 | 26.2 | 28.2 |\n| 29 | 14.0 | 17.5 | 20.4 | 23.0 | 24.2 | 27.2 |\n| 28 | 13.1 | 16.6 | 19.5 | 22.0 | 24.2 | 26.2 |\n| 27 | 12.2 | 15.7 | 18.6 | 21.1 | 23.3 | 25.2 |\n| 26 | 11.4 | 14.8 | 17.6 | 20.1 | 22.3 | 24.2 |\n| 25 | 10.5 | 13.9 | 16.7 | 19.1 | 21.3 | 23.2 |\n| 24 | 9.6 | 12.9 | 15.8 | 18.2 | 20.3 | 22.3 |\n| 23 | 8.7 | 12.0 | 14.8 | 17.2 | 19.4 | 21.3 |\n| 22 | 7.8 | 11.1 | 13.9 | 16.3 | 18.4 | 20.3 |\n| 21 | 6.9 | 10.2 | 12.9 | 15.3 | 17.4 | 19.3 |\n| 20 | 6.0 | 9.3 | 12.0 | 14.4 | 16.4 | 18.3 |\n| 19 | 5.1 | 8.3 | 11.1 | 13.4 | 15.5 | 17.3 |\n| 18 | 4.2 | 7.4 | 10.1 | 12.5 | 14.5 | 16.3 |\n| 17 | 3.3 | 6.5 | 9.2 | 11.5 | 13.5 | 15.3 |\n| 16 | 2.4 | 5.6 | 8.2 | 10.5 | 12.6 | 14.4 |\n| 15 | 1.5 | 4.7 | 7.3 | 9.6 | 11.6 | 13.4 |\n| 14 | 0.6 | 3.7 | 6.4 | 8.6 | 10.6 | 12.4 |\n| 13 | -0.1 | 2.8 | 5.5 | 7.7 | 9.6 | 11.4 |\n| 12 | -1.0 | 1.9 | 4.5 | 6.7 | 8.7 | 10.4 |\n| 11 | -1.8 | 1.0 | 3.5 | 5.8 | 7.7 | 9.4 |\n| 10 | -2.6 | 0.1 | 2.6 | 4.8 | 6.7 | 8.4 |\n| 9 | -3.4 | -1.0 | 1.6 | 3.8 | 5.8 | 7.5 |\n| 8 | -4.4 | -1.5 | 0.7 | 2.9 | 4.8 | 6.5 |\n| 7 | -5.0 | -2.4 | -0.2 | 1.9 | 3.8 | 5.5 |\n| 6 | -5.8 | -3.2 | -1.0 | 0.9 | 2.8 | 4.5 |\n| 5 | -6.7 | -4.0 | -1.9 | 0.0 | 1.8 | 3.5 |\n\nExample:  \nAt +15 °C air temperature and 80 % relative humidity, condensation begins at a surface temperature of +11.7 °C.
