The Term "Wood Preservative" Refers To Products That Inhibit The Degradation Of Wood From Fungal Decay, Sapstain, Molds, And Wood-Destroying Insects

Depending on the function of the wood and the overall purpose of preservation, a variety of compounds are utilised. Chromatized copper arsenate is the most prevalent chemical used outside of homes (CCA). Although chromium retains them both in the wood, the CCA Wood Preservatives employs copper as a fungicide and arsenic as an insecticide. This gives the wood a faintly green tint, which is typical of outdoor fences, decks, and power poles.


Arsenic is so hazardous that many localities have abandoned CCA-based new building. Most wood preservatives now use copper azole or alkaline copper quaternary (ACQ) in its stead (CA-B). Wood Preservatives function similarly to CCA but with less of its unfavourable side effects. The high copper content of ACQ has the drawback of destroying iron and steel, which increases building prices significantly.


Many additional compounds are utilised in addition to copper. Borate and silicate-based compounds are two of the most popular non-copper compounds. They offer sufficient preservation but just a little amount of pesticide. Also, in certain regions, these chemicals render the wood unsuitable when exposed to water because they leak out of it.


Copper is the most frequent material used in non-industrial wood. Heat and fire treatment are the most frequent pure mechanical treatments. In every situation, a wood preservative seeks to dry out the wood without causing it to split or break.


Pitch or tar was once used to Wood Preservatives. In certain cases, these materials are still utilised to preserve wood today. Pitch and tar are often administered by their own petrochemical components, which lessens part of the filth that comes with them.
