How conditions after application affect the depth of penetration of gel wood preservative in oak

Popis výsledku v původním jazyce

Wooden constructions are often attacked during use by biotic agents such as wood-rotting fungi and wood-boring insects, and this can happen to wooden buildings in open-air museums. Chemical preservatives containing toxic active substances can provide preventive and controlling protection against wood-boring insects. Such preservatives in gel form are claimed to penetrate more deeply into wood than liquid preservatives applied to the surface. Preservative in gel form was applied to the surface of European oak samples, which were stored for 14 days under three different conditions of air temperature and humidity that simulate climatic conditions in different seasons. The penetration depth and retention of permethrin, the active substance in the gel, was analysed at successive layers using high-performance liquid chromatography. The permethrin penetrated to a depth of at least 10 mm, where its retention satisfied the requirements for its efficacy, but the declining concentration gradient was steep with increasing depth. Storage conditions that promoted gel drying led to less penetration of permethrin.
