Blue stain of wood is a condition which considerably reduces the commercial value of sawn timber. The fungi responsible for the development of blue stains particularly often attack lumber in spring and summer. Stains appear in the structure of the material stored for a long time at high temperatures. They are wedge-shaped or ring-shaped (forehead) or dots and streaks (sides of lumber). This process is called raw blue stain.
Although blue stain does not affect the mechanical properties of sawn timber, it significantly lowers its value, as it indicates a poor storage method. Such a raw material will also not find recognition in carpentry due to its reduced aesthetic value. However, the symptoms of blue stain do not eliminate the raw material. Various half-measures in the form of more or less effective mixtures of antifungal and bleaching substances have been used for a long time. The time of half-measures, however, is over. We no longer have to rely on good advice or communal news. The tried and tested Weiss Holz agent dedicated to fighting blue stain has been introduced for sale. It is a strong agent that also works as a bleach. The use of Weiss Holz will effectively avoid the loss of sawn value – it is worth remembering that in summer, freshly cut wood can darken very quickly, thus losing its value. This is where a proven agent with an established position on the market comes in handy (it is used on a large scale in sawmills).
Because the article about the bruise of wood enjoys unflagging popularity. Based on the questions asked, we know that he has not fully exhausted the topic. We decided to expand the substantive part a bit to bring the issue of combating blue stain to our customers even better.
What is the blue stain of wood and its influence on the performance of wood?
The blue stain of wood is an aesthetic disadvantage of raw wood consisting of gray, gray, steel and even black color of the wood. This discoloration is the result of the development of fungi in the wood (namely the imperfect Deuteromycetes and Ascomycetes belonging to the fungi). Microscopic examination confirms that the fungi grow mainly through funnel-shaped pits, directly damaging the tubular cell walls only to a small extent. The structure of the wood remains intact in practice. Thus, the influence of blue stain on its mechanical properties is negligible. The infected parts of the raw material retain their utility values, however, due to their unsightly appearance, they are not suitable for use in carpentry or construction. Everywhere where elements made of it will be displayed and are to be a decorative element. The material affected by blue stain, despite only aesthetic defects, was losing its value, and finding buyers is problematic.
