Peter Müller has no longer been using creosote for impregnating wood since 2023. For equestrian fencing, a new DeepProtect treatment has replaced tar oil.
Here is a description of this historical activity.
Pressure impregnation for comprehensive wood impregnation
Creosote impregnation is recommended when there is little chance of skin contact and the wood must last a long time.
Peter Müller impregnation cycle for class 2 wood
- Pre-pressure phase: The impregnation agent is heated in the boiler. The pre-pressure phase allows the wood to acclimatise to the creosote.
- Pressure process: The agent is pressed into the wood.
- Vacuum: The agent is pumped into the holding tank, allowing the wood to drain.
We use only type C creosote. This creosote is more ecologically friendly and gives off fewer odours than other types of creosote.
Pressure units and times vary depending on the type of wood. Since only sapwood can be impregnated, some types of wood lend themselves better to impregnation than others.
