The risk of wet wood
Wood is indeed a unique and interesting material. Wood is a natural raw material with properties that are ideal to make various household product. Wood is obtained from trees that are natural and friendly for human health and environment. But the fact, to handle the wood is also not so easy. To produce good wood products from wood, the wood are need to be processed properly.One of the most important thing is the moisture content of the wood. The wood are need to be dried until meet a certain standard before go to the woodworking process.
The ideal wood moisture content of wood is the moisture content in balance with air humidity at the place where wood products will be used. For example if we want to make furniture products that are going to be used in New York, then we should see the average humidity data in New York; it is averagely 56% to 72% (data is taken from City rating .com). From these data then we go to find data of the wood moisture content in accordance with the air humidity (see chart wood moisture content vs. air humidity). From this chart we find the ideal moisture content of wood is about 10% to 14%. So the standard moisture content of the wood that is used to make the furniture should be in range in between the 10% to 14%.
The drying process of the wood may be considered as a difficult and costly process but it is a very critical thing in the woodworking industry. The wet wood is high risk to emerge many problem that may become very expensive to be fixed if it happened.
Here are the problems that can occur due to the use of wet wood.
- Wood is cracked, warped, bent or other construction problems.
the wood cracked caused from the wood movement
- The fungi problem on wood.
the fungi in the wood
- The finishing problem.
The water vapors in the finishing layer will also affect the strength of finishing because since it make the imperfect bonding in the finishing layer.
For finishing process that uses water-based finishing material, the problems caused by wet wood are more. The water in the wood will release and affect the water releasing from the finishing materials. It makes the drying process become longer and difficult and finally will make some more finishing problem.
The problem caused by the wet wood is only can be solved by drying the wood until it meet the standard moisture content. If the furniture is already built and finished it means that we have to wash the finish, let dry, fix the construction problem and refinish. It will be a high cost process, since the lost of materials, time and energy. Since that the uses or wet wood should be avoided in the furniture making. It is much better to wait until the wood is dry an stable when we start using it in the production process.
