Pine wood

Pinewood has been very popular in the woodworking industry since long time ago. The pine trees can be found in many places around the world. The pine trees spread trough out the Europe, North America and well known as the evergreen trees. But some species of the pine wood is also available equator area. The wood has been used to make many wood product such as: furniture, house, fences, and many household products. Although it is classified as the softwood but it is quite strong and tough. He has medium hardness and easy to be handled in the woodworking industry. He has a yellowish-white light color with beautiful wood grain; with proper finish it can give a beautiful appearance. With his less expensive price, it becomes the favorite substrate for many woodworker.
There many species of pine wood, each of which can have different properties. In general the pine wood has a beautiful grain pattern. With his light (white) it can be finished with wide range color with attractive appearance. The grain pattern, color base and the physical properties of this wood could be varied depending on the species and origin of the wood.

Here are some things need to be considered when we deal with pine wood.  

  •      The fungal attack.

The pine wood is susceptible to the fungal attack. To avoid this problem then the processing from the logging, sawmills and drying must be done correctly. The improper process will lead to the emergence of fungi that will cause the blue stain. The blue stain in the wood will ruin the color and decrease of the wood quality. Treatment with anti fungal chemical is highly recommended to prevent the fungal attacked. Especially when we consider that the tress is mostly grow in the highland area where it is usually humid and rainy. 
  •   Oil in the wood.
The pine wood contains oil or resin inside. This oil makes the wood naturally become stronger and more resistant to the insect attacked, but the presence of the oil can be problem, at the finishing appearance. This oil can come out as a yellowish-brown stain that ruin the finishing looked; the oil can also disturb the adhesion of finishing materials. The oil need to be handled properly to minimize the problem resulted.See our previous article: oil problem at the pinewood

  • Variation in the color and grain.
There are many species of pine tree, each of which can have different color and grain pattern.  Too big variation could bring to the different appearance at the final finish product. Then when we process this wood to make product, make sure we check the wood grain and color base.  Match the color and grain look as much as possible at the beginning of production process. It is better to match the wood grain and color  when we laminate the wood or do the assembling. If we make the veneer then the matching must be dome at the veneer setting. By this way we can control the final appearance to get the uniform color an looked. We may use the sap stain or equalizer stain to uniform the color, but it could be costly and make the finishing process more complicated. The sap stain and equalizer stain is also cannot solve the problem caused be the variation at the grain. .

  • Pine wood must be considered as soft wood.
There are many type of pine wood, but generally this is a soft wood. The wood is not strong and hard enough for some product. The wood is not recommended to be uses for construction that need maximum strength and hardness. For example the uses of pine wood to make chair must  be carefully constructed to make sure it is strong and safe enough.

As a softwood it also needs proper sanding. The wood has lot of wood fibers that make could be difficult to be cut off at the sanding process. We need the new and sharp sandpaper to do the sanding. Always replace the blunt sandpaper with the new one when we do sanding. The blunt sandpaper won’t cut off the wood fiber but will make the wood fiber to lay down at the wood surface. It will lead to the blotchy color at the stain application since the uneven stain absorption. The glue size or sealer size is recommended to minimize this problem.
