Contrary to what one might think, the varnishes, waxes and other lacquers that are generally used for the maintenance of wood have many chemicals. In addition to attacking the wood of your parquet or your furniture, they have been defined as products harmful to health and the environment. It is for this reason that we recommend using a natural product such as linseed oil. This natural liquid solution of golden color is obtained by pressing the ripe seeds of flax cold or hot. It can be used pure or mixed with other oils, solvents or resins. One thing is certain, it has nothing to envy to the products sold on the market ...
The different types of linseed oil
There are three different types of linseed oil on the market, the main characteristics of which are as follows:
- Crude linseed oil: it is obtained from flax seeds with cold pressed fibers. It is untreated, which means that it is 100% natural and easily penetrates into wood. However, be aware that it tends to stain wood slightly.
- Cooked linseed oil: this type of linseed oil is heated to a low temperature. It is an oil to which a siccative has been added so that it dries faster.
- Raw or refined linseed oil: this undergoes heat treatment by polymerization. In other words, it is heated to more than 280 ° in order to make it more resistant. This type of linseed oil is the most qualitative in terms of result. It wants to be more robust and it does not yellow the wood. The catch? It takes longer to penetrate the wood and its price is higher.
Note: for an impeccable result, it is recommended to use a crude linseed oil for the first layer and to apply a cooked linseed oil for the second layer. The first will have the advantage of drying quickly and the second will soak perfectly into the wood for a perfect finish!
What to do with linseed oil?
Linseed oil is a great ecological product for treating wooded surfaces. Its application will nourish and protect the wood by depositing a protective film. How? 'Or' What ? The molecules of linseed oil saturate the pores of the wood, thus becoming water repellent. It can be used on a work surface, furniture or even parquet. Besides, linseed oil is particularly used for oiled parquet floors. It will also be used on terracotta floor tiles or pots and cork. It is also the ally of wood on the outside because linseed oil will saturate the wood of garden furniture for example and thus make it waterproof. It therefore protects from humidity while allowing the wood to breathe. It is also recognized for its anti-dust and anti-insect action as well as its resistance to external aggressions. Note that linseed oil can be used as well to give a little character to a new wood as for the restoration of older woods such as parquet or exposed beams of an interior.
The good news ? In addition to being natural and therefore more ecological, linseed oil is also economical! The liter is two to three times cheaper than a conventional varnish! Count on average, around 5 euros per liter.
