How to Preserve Wood! Termites Guaranteed to Go

Navigasi - Each type of wood has different physical, mechanical, and chemical properties that affect the level of wood durability. Wood such as teak, ironwood, rosewood, meranti, and bangkirai are examples of wood with a high level of durability. Meanwhile, kapok and sengon wood tend to have a shorter lifespan.

The durability of wood is also influenced by environmental conditions, such as humidity, moisture content, exposure to sunlight, fungal attacks, termites and so on. Therefore, several wood treatments are needed to increase the durability of wood, both traditional and modern.

Wood Quality

The need for logs for the timber industry in Indonesia continues to increase every year. In 2013, the demand for wood reached 40 million cubic meters. About 60% of these needs are met from plantations. This condition is much better than in the 1990s, where 90% of the timber supply came from natural forests.

Although there has been improvement in terms of wood supply because it comes from plantation forests, wood from this type of forest generally has lower quality and durability. The reason is the use of wood at a young age which tends to be vulnerable to termite attacks.

Research conducted by Dodi Andika (2015) explains that this vulnerability causes losses due to termite attacks on houses in Indonesia reaching 8.7 trillion rupiah throughout 2015.

These disadvantages require solutions on how to extend the life of wood and increase its resistance from bio-deterioration attacks through preservation methods without toxic chemicals that can have a negative impact on organisms, including humans.

How to Preserve Wood

Preservation of wood aims to increase the service life for a longer time, especially the types used for building construction and household furniture.

The following are wood preservation techniques that are often used by the community, namely:

Soaking the Wood in the River

Soaking logs and logs in rivers is an easy way to preserve and improve wood quality. The purpose of this immersion is so that the wood absorbs water so as to trigger the release of water-soluble extractive substances, such as nitrogen, glucosides, tannins and wood dyes. Meanwhile, water-insoluble extractive substances such as starch remain in the pores of the wood.

The soluble extractive substances affect the condition of the water around the wood. Microbes such as Bacillus subtilis, Bacillus masentriricus, Lactobacillus sp., and Staphylococcus sp. will develop and decompose wood extractive substances that are not dissolved so that it will gradually dissolve. This process is known as chain fermentation.

This chain fermentation process produces organic acids, gases and alcohol and reduces the moisture content in the wood. In addition, the content of wood starch which is a source of destructive food such as termites will also decrease because it dissolves into water. The result is increased wood resistance due to reduced interest by destructive insects to eat wood.

Soaking the Wood in the Pool

Soaking wood in the pool with the addition of natural ingredients can also preserve wood. Banana fronds, tobacco leaves, rice straw, and clove flowers are natural ingredients that are usually used. The soaking process generally takes 2 to 3 months to achieve maximum results.

Before soaking the wood, the wood must be washed for 7 consecutive days. The water used for washing is a mixture of 1 liter of water with 10 grams of tobacco, 10 grams of cloves, and 10 grams of banana stems. The mixed water is rubbed over the entire surface of the wood and then dry using a cloth.

After washing for 7 days, the wood is then soaked into the pond and added with natural ingredients. After the soaking process for 2 to 3 months is complete, the wood must be dried first to dry it under the shade.

Mix of Oil and Diesel

Used oil can also be used to preserve wood and extend its life. The trick is to make a liquid from a mixture of oil and diesel in a ratio of 1:1.

Apply the liquid on the wood surface evenly using a brush. Then leave it for a few days for the liquid to absorb and dry naturally.

In order to get maximum results, before the wood is used for building construction, it can be smeared again with liquid oil and diesel in a ratio of 1:2. If the wood will be shaved, then the basting is done after the wood is shaved.

Wood Smoking Technique

The smoking method has not been widely used by the community to preserve wood. Fumigation of wood is carried out for 3 days so that the quality of the wood increases. The type of wood that is usually smoked is sengon wood and pulai uses mangiun wood as fuel.

Painting Wood

Coating wood with paint is the easiest way to make wood last longer. The paint used can be wood paint, oil paint and varnish. However, the durability of using wood painting methods is not as durable as other techniques.

Vacuum Preservation of Wood

Usually the method of preserving wood with a vacuum system is carried out by large-scale wood companies. The advantages of this method are the penetration and retention of preservatives are very high, the work process is fast and can be applied to wet or dry wood. However, this method also has drawbacks, namely high costs and a high level of work accuracy.

Preventing the Hazards of Wood Preservatives

The process of preserving wood often causes environmental impacts and affects health. Therefore, preventive measures are needed so that we avoid the dangers of wood preservatives, including:

  • Do not preserve wood products if they come in direct contact with food. Examples are plates, food racks, and so on. Chemical preservatives can affect the user's health.
  • Do not preserve the wood used for the table top (table top).
  • Use wood preservative only in areas that are easily visible, such as hardwood floors or wall panels.
  • Do not use wood preservatives that interact directly with clean or drinking water.
  • Discard the remaining wood that has been preserved by burial. Should not be used for firewood because the smoke contains chemical preservatives.
  • Avoid sawdust or sandpaper dust that comes from preserved wood.
  • For wood preservation workers, always keep hands and other body parts clean, especially before eating or drinking.
  • If the clothes we wear are contaminated with wood preservative chemicals, then separate them from other clothes when washing.

Various ways to preserve wood above we can apply before using wood for various purposes. In addition, currently there are many effective wood preservative products that we can use as an option to get a longer durability of wood.
