Protective Properties of Traditional Wood Paint Based on Cattle Blood

Popis výsledku v původním jazyce

In the past, cattle blood was used for painting in central Europe mainly for interior wooden elements. Unfortunately, this common wood-coating technique of the past had vanished during the 20th century and only many misinformed opinions are left about this coating&apos;s purpose and its effects on wood durability. Three different recipes were used for beech and pine sapwood treatment, which were tested for their durability against wood-rotting fungi and termites. The fire retardancy of blood-based paints and its color change during the hardening process was determined as well. Over the course of time the bright brick red color of the coating turns a dark brown color. The coating surface layer did not protect the wood against either white- or brown-rot fungus; it is rather a source of nutrients necessary for a fungi degradation activity. The specimen treatment with the blood-based paint did not avoid termites feeding on wood, however the overall mortality was reached at the end of the test. The higher pH of the treated wood and/or available amount of micronutrients could be plausible explanations. Although fire retardancy of the coating was not proved, flame-exposed spruce wood with the coating did not show significantly improved fire resistance compared to untreated wood.
