In apiculture, a variety of equipment is made of wood and usually requires a protective coat. E.g. tools, bee houses and beehives. But how to protect them best?
Coats based on linseed
Coatings based on natural linseed oil generally contain terpenes and additives, e.g. cobalt compounds to ease the drying processor. Nature oils are easily affected by fungi and are often equipped with anti-fungi agents, because they would otherwise go bad. In most cases it must be applied often, because also already applied oil can be affected by fungi. Additives such as cobalt compounds or anti-fungi agents are a concern for the health of humans and animals in the application process, but also when already dried. They also have great potential for allergies. The danger of spontaneous combustion of linseed oil should also not to be underestimated. The improper handling of rags soaked with linseed oil or brushes repeatedly leads to fires.
Untreated wood and the consequences
In fear of their bees many beekeepers waive therefore completely treating wooden parts. To leave wood unprotected carries risks - also for the bees. Penetrating moisture can lead to infestation of wood with stain or other moulds, partly latent in areas that are not easy to see. Mold is conducive neither to the bees, nor for the honey.
Wood is a natural raw material and responds to temperature and humidity changes in particular with dwindling, warping, cracking or warping. In short: it works. Cracks and drafts can arise, which lead to infiltration and cold / thermal bridges that can endanger the feel-good climate of the bees of 35 ° C which is especially important for the breed. Certainly smaller drafts and cracks are sealed by the bees using propolis, the openings, however resulting from a missing protective coat, take up the working power of bees, which would be better to invest in the collection of nectar.
Temperatures drop after rain
For many bee-keepers, the rapid temperature drop in untreated hives represents a tremendous problem, for example, after a rain. This extreme temperature drop of partially up to 20 ° Celcius is created through evaporative moisture. Compared to refrigerators, where this effect is used to cool our food. In beehives and houses, this is however undesirable and can be prevented by a coating them with PIGROL beehive paints.
Not only from an environmental and economic point of view a protective coat with PIGROL Farbnatur Beutenschutzlack und Beutenschutzlasur is recommended. It is a substantial benefit for beekeepers and their colonies!
