Seasoning reduces the likelihood of stain, mildew, or decay developing in transit, storage, or subsequent use. Blue stain fungi and wood-destroying fungi cannot grow in wood with a moisture content of less than 20 percent. 2. The shrinkage that accompanies seasoning is made to take place before the wood is put to use.
Why is it important to seasoning timber before use?
Seasoning is the process of drying timber to remove the bound moisture contained in walls of the wood cells to produce seasoned timber. … Seasoned timber tends to have superior dimensional stability than unseasoned timber and is much less prone to warping and splitting in service.
Why seasoning of wood is required?
The process of inducing evaporation of the moisture contained in wood; a type of hydrothermal treatment of wood is known as wood seasoning. The purpose of seasoning is to reduce the moisture content in the wood to a level appropriate to the use of the articles made from the wood.
What are the disadvantages of seasoning timber?
- It needs a larger space for seasoning.
- This process is long and depends on natural air.
- In natural seasoning, the ends of timber dry fast and split. …
- During the natural seasoning, there is a possibility of fungal and insect attack.
What are benefits of seasoning?
1.To increase dimensional stability. Wood shrinks across the grain (not along the grain) when it dries. If wood is cut to size before it is seasoned, it will shrink during drying and thus be undersized in its final form. 2.To reduce or eliminate attack by decay or stain.
What are the two types of seasoning of timber?

What are the advantages of kiln seasoning?
- The moisture content can be reduced as per requirement.
- The timber can be seasoned thoroughly well and in a short span of time under controlled conditions.
- The timber seasoned by this method is less liable to shrinkage.
- The wood can be used immediately as and when required.
What is the artificial seasoning of timber?
Artificial seasoning is the process by which lumber is dried using man-made devices such as a kiln. Regular wood seasoning is done by air drying in conditions below 18 percent moisture. There are multiple advantages to having wood artificially seasoned that relate to the quality, strength and cost of the wood.
What are the advantages and disadvantages of natural seasoning of timber?
State two advantages and two disadvantages of Air / Natural Seasoning. Advantages: Inexpensive, Easily managed, No specialist labour required, No expensive equipment needed. Disadvantages: Slow, No control over final MC, MC of only 18% achievable, Weather dependent, ￼￼￼Boards prone to fungus/insect attack.
Which is not an objective of seasoning timber?
Reduction of natural defects in timber. Reduction in shrinkage and warping.
What happens during kiln seasoning?
A drying process predominantly utilized for reducing the moisture content in timber. The process is carried out in a closed chamber, providing maximum control of air circulation, humidity, and temperature. … One advantage of kiln seasoning is that lower moisture contents are possible than can be achieved using … …
What are the advantages of natural wood seasoning?
- To increase dimensional stability. Wood shrinks across the grain (not along the grain) when it dries. …
- To reduce or eliminate attack by decay or stain. …
- To reduce the weight. …
- To increase the strength.
What are the different types of seasoning timber?
- Natural Seasoning. Water Seasoning. Air Seasoning.

What is the process of seasoning timber?
The process of drying out the water from “wet” or “green” timber is termed “seasoning”, or more simply “drying”. … Drying the moisture out of wood enhances its properties to such an extent that the resulting timber is given the special name “seasoned” rather than “dried” although the terms are identical.
