Wood in its original form is unique and not interchangeable. A proof of the existence of individuality.
Wood - home value for generations promises duration.

Wood as a building material has been known to us for centuries and as such is very pleasant. It conveys us a feeling of security and well-being, whether in nature or in rooms.

It can easily be used as a building material, flooring or even for furniture. From the nature we know that the surface of this material needs only limited protection. To the power of wood on us, it requires one condition - we must not isolate its surface with materials not isolate its surface with foreign materials.

Through the treatment with vegetable wood preservatives (and paints) the wood is supported in its it remains permeable and retains its own valuable character. character.

In the past, the wood was protected with oils and waxes, which led to an increase in the resistance and water repellency, but resulted in susceptibility to stains.
At the end of the 1930s, the first synthetic varnishes appeared on the market, which were highly appreciated by architects, architects, craftsmen and also end users. They were easier to easier to work with, more resistant and easier to maintain.

The problem of chemical substances was not yet known at that time. only the smell of the acid-hardening varnish was a nuisance. Since the demand was enormously high, the progress of the and so the formaldehyde-free DD coatings, also known as PU coatings, came onto the market. came onto the market.

In the 1960s, the environmental impact of these paint systems was recognized, which had a very high solvent content and harmful substances. Not only during production, toxic substances are released not only during production, but also during processing and during the curing substances are released. (Sick Building)

With acrylic paint, also known as water-based paint because it is diluted with water, the synthetic paint industry responded to the new requirements: In the aggressive paints, the turpentine oil is replaced by water and supplemented with glycols and aziridines. With less than 10% solvent content, they received the "Blue Angel" label (low pollutant content).
At the beginning of the 70s, natural varnishes and oils were developed for industrial production for the first time. developed. Thanks to new technologies and findings in plant chemistry, natural products were refined and made easy to process. New results show that such systems are on a par with DD coatings, if not even preferable to DD coatings in terms of reparability and durability. are to be preferred.

When treated with products from plant chemistry, the natural defenses that the tree has built up are the natural defenses built up by the tree are protected by related substances, and protect in a similar way as the tree bark.

The need to surround oneself with natural substances and to protect the environment, a requirement that we meet with our products and processes.
Let us advise you and convince you of the advantages of plant chemical products. products.

NATURAL SURFACE TREATMENT IN OIL AND WAX

Wood is a natural product and therefore a renewable resource.
For this reason, we like to surround ourselves with this building material, which has a high filtering effect, is breathable, regulates humidity and thus conveys warmth and security. warmth and security.

In order not to destroy these natural properties and to preserve their beauty and and easy care for a longer period of time, we use with the FISCHER-SYSTEM we also use renewable natural products to protect the wood as a surface treatment.

With the FISCHER-SYSTEM, the wood is saturated with an oil consisting mainly of linseed oil. is saturated. Due to this impregnation the oils penetrate particularly deep into the wood (molecules are approx. 10 times smaller than the narrowest passage in the cell system of the wood).
This open-pored treatment has an elastic, water vapor permeable and and water-repellent effect, which takes any expansion and contraction of the wood of the wood. It protects the wood from the inside, makes it more resistant and revitalizes its structure.

To avoid the time-consuming re-oiling and simplify cleaning, a hot wax (beeswax) is applied to the wax (bee carnauba wax) is applied very thinly and polished in. polished in. Without clogging the pores, the wax forms a bond with the wood. with the wood. The well-balanced combination of plant waxes and oils results in a closed closed, step and slip resistant surface.

The prerequisite for the FISCHER-SYSTEM is a very good sanding of the wood surface.
Since this process does not produce a coating, there must be no sanding marks left after fine sanding (grit 150), no sanding marks should be visible. For this purpose, Fischer-Verfahrenstechnik uses machines for coarse and fine sanding, for new parquet as well as for parquet to be parquet to be renovated.

Oil-wax treated surfaces are easy to maintain and offer an allergy-free allergy-free, pleasant and health-promoting room climate.
