Hot and cold soaking  preservation of wood

• Select wood to be treated

Hot soaking

• Use a suitable preservative that can be safely heated
• Heat the preservative to a recommended temperature. This helps better penetration of the preservative into the wood
• Submerge the wood completely in the hot preservative for a specified period of time.
• Remove the wood from the preservative and dry completely before use

Cold Soaking:

• After hot soaking, immediately transfer the wood to a cold preservative bath. This sudden temperature change causes the wood to contract, creating a partial vacuum that draws more preservative into the wood.
• Leave the wood in the cold bath for an extended period, often several hours to a few days, to ensure deep penetration.

Drying:

• Take the wood out of the cold bath and allow it to drain.
• Let the wood dry completely before use. This can take several days to weeks, depending on the wood type and environmental conditions.
