Oil Problem in Pine Wood

Pine wood is one of the most popular in the wood industry. Pine trees are much planted to green the mountain, and the wood is used for industrial purposes. The pulp, chemicals, or woodworking are the industries that use the pine timber. In the woodworking industry, pine wood is used to make many wood products. It is used as material for making furniture, house frames, doors, windows, and flooring parquet. The pine wood has many species; about 125 species are known. The character of the pine wood may vary depending on the species and the place it grows. But generally it is soft wood, with a light yellow base color, and inexpensive. The wood has a strong character of grain but with fewer pores and grain texture, which makes the wood liked by the wood furniture manufacturer. With the proper finishing, it can produce a wood product with a beautiful and attractive appearance.
But the pine wood needs to be handled properly. The wood has oil that could lead to problems if it is not well handled. The pine oil is actually resin that is useful in the chemical industry, but it may interfere with the utilization of the wood in the woodworking. The pine oil may interfere with the color of the finished wood. In the waxed finish, the oil from pine wood could make the wax difficult to dry. The oil will mix with the wax and stay as a sticky wax. For wood finishes with thick pigment, such as the solid color finish or wash finish, the oil will come out as a yellow stain that will ruin the finishing look. Since that, the oil in pine wood should be anticipated to make good products in the woodworking industry.

How to overcome the oil problem from the pine wood.

• Choose the proper finishing.

The pine oil will come out through the wood knot only, and casually it won't be a problem for the gluing and construction process. The oil is also not going to bother the wood is the wood is finished in the transparent color. The oil will blend and camouflage with the wood color and does not seem in the finishing appearance. Pine oil is yellow in color and will be clearly visible on finishing with solid colors or wash color when the thick pigments are used. Since that, you better use the transparent color for the pine wood products. The natural color finish, or the brown wood finish, is a good choice since it will enhance its beautiful and unique grain and also minimize the oil problem.

• Selection and treatment of the wood.

The oil will come through at the knot parts. It won't come out of the other part of the wood; therefore, you can solve the oil problem by disposing of the knots part. It may be costly, but it may be a good option for some conditions.
The oil comes out together with the release of water vapor from the wood. The wet wood has a higher risk of getting the oil problem. For a wide and big surface, then the use of wood veneer is a better option. Veneer is cheaper and can be easier selected before it is laminated to the core. Veneer is also a thin layer, which has less oil than the thick, solid wood. Veneer is also marketed in dry conditions, making it less risky for the oil problem.

• Use the oil block.

Pine wood has been used since a long time ago, and since then people have recognized his oil problem. The finishing industry manufacturer has created special material that can be used to overcome the oil problem. It is a kind of sealer that can be applied to the wood knot to block and stop the oil from coming out. There are may some different names for this material, such as pine knot sealer, oil pine stop, oil pine sealer, etc. You can get the oil block from the paint store by explaining that you are dealing with pine wood. It can be applied by brushed or dripped at the knot parts, and most of them work well to solve the oil problem.
The oil block will affect the stain absortbion that will affect the color. Since that, it should be used only for solid color or wash finish. You don't need the oil block for the transparent finish color. The oil block even can ruin the transparent finish since it will interfere with the stain absorption by the wood.

Apply the oil block sealer by brush or spray at the wood knot, and let it dry. It usually needs about a few minutes to dry, then sand the sealer before starting the finishing process.
