The Various Methods of Seasoning Lumber 1. The Natural Sunlight or Air Seasoning Process - is considered as one of the best method used in seasoning of wood although the period involved is relatively longer. 2. The Natural Seasoning - is a process wherein the lumber is attacked in a drying kiln and then exposed to steam and hot air. Wood from this process undergoes quick drying and is classified as somewhat inferior in quality compared to those lumber which are seasoned by the natural sunlight or air seasoning process. The Artificial Methods of Seasoning Wood are: 1. By Forced Air Drying 2. By Kiln Drying 3. By Radio Frequency Dielectric Drying Good seasoning is the primary consideration for a successful preservation of wood. Wood does not decay naturally through age, nor will it decay if it is kept constantly dry or continuously submerged in water. The Common Causes of Decay in Wood are: 1. Alternate moisture and dryness 2. Fungi or molds 3. Insects and worms 4. Heat and confined air The Process of Preserving Wood are: 1. External - the wood is coated with preservative (applied as paint) which penetrates the fiber of the wood. 2. Internal - a chemical compound is impregnated at a prescribed pressure to permeate the wood thoroughly.
