Winter Application of Grafo-Therm
The application and masking process would be exactly the same as the summer. When you are finished rather than allowing the Grafo-Therm to dry naturally, the coating must be force dried. This is essential before the coating is subjected to either frost or condensation.
We have found the most effective and economical way to dry the coating is to use diesel fired space heaters. Although gas space heaters will work it does tend to be more expensive. We recommend the use of the largest feasible indirect fired space heater.
Space heaters are available from numerous hire centres throughout the UK. They are available with ducting which enables accurate direction of the heat to all required areas.
Drying times are greatly effected by the weather and relative humidity on the day, so it is difficult to give an accurate drying time. For best results we have found that spraying is completed as early in the day as possible. This increases drying hours. After 3pm in the UK drying slows significantly, so any extra time before is a benefit.
