Quick Answer
Cordwood should be cured for at least 6-12 months before use, depending on the moisture content and weather conditions. This allows the wood to dry out and the mortar to set properly. Curing time may vary based on the specific climate and storage conditions.
Curing and Drying Requirements
Curing cordwood involves allowing the wood to dry out and the mortar to set. The ideal moisture content for cured cordwood is between 15-20%. To achieve this, cordwood should be stored in a well-ventilated area, ideally with a roof and walls to protect it from the elements. The cordwood should be stacked off the ground to prevent moisture from seeping in and to allow for air circulation.
Moisture Content and Curing Time
The curing time for cordwood depends on the initial moisture content and the weather conditions. As a general rule, cordwood with a high moisture content (above 30%) should be cured for at least 12 months before use. Cordwood with a moderate moisture content (20-30%) can be cured for 6-9 months, while cordwood with a low moisture content (below 20%) can be cured for 3-6 months.
Preparing Cordwood for Use
Before using cured cordwood for construction, it’s essential to inspect the wood for any signs of decay or damage. Remove any rotten or damaged wood, and check the wood for any cracks or checks. The wood should be free of any debris, leaves, or other contaminants that could affect the mortar or the overall structure. Apply a layer of mortar to the wood, and begin construction as usual.
