Disadvantages of preparing and using resin (bitumen) and oil mixtures:

[zihadhosenjm40]

a viscous coating made of heavy petroleum products effectively protects the product from the penetration of moisture and atmospheric oxygen;
the anaerobic environment of wood protected with bitumen stops the development of bacteria and fungi, destroying existing colonies of microorganisms;
Wood-boring insects cannot appear in wood treated with hungary mobile database or oil. For their existence, only weakened (rotten) wood and the absence of resins and hydrocarbons harmful to any organism are necessary.
Wood treated with heavy petroleum products (often with the addition of coke-chemical substances) does not deteriorate in the ground for years. It is enough to recall the telegraph poles that stand for decades without a hint of decay.


toxicity of components;
highly flammable if not prepared correctly;
high soiling of the compositions, which are almost impossible to wash off if they get on clothes;
unpleasant odor;
impossibility of use due to unpleasant odor and toxicity indoors.
Traditional mixtures for wood treatment are aqueous solutions of salts - sodium fluoride and copper or iron sulfate. Their low concentrations are used to cover the external and internal parts of wooden structures and finishing items. More saturated compositions help protect piles or boards buried in the ground.

Advantages of saline water solutions:

less toxic than non-aqueous impregnations. The only thing that poses the greatest danger is copper sulfate (copper sulfate), which can cause severe poisoning if swallowed;
simplicity and safety of preparation. Heating the mixture over an open fire is no more dangerous than making a regular fire;
ease of transportation. Bitumen or oil are more difficult to transport to the place of use, but salts are easily transported over any distance.
The disadvantages of water-based antiseptics include:
