EKJU products will serve you a long time if you restore the wooden surface regularly (once every 4-5 years)
During the daily production process, EKJU complies with the exact pressure impregnation technology and uses high-quality impregnation agent CELTUTRE C4.
It is a water-based wood protective, which contains copper and organic biocides (azoles).
CELTUTRE C4 treated timber has a lasting protection against fungi, insects and woodworm attacks, during the contact with the atmosphere and the earth.
Wood products treated with CELTUTRE C4 are safe to use on applications involving contact with children and other frequent human contact situations. None of the ingredients in CELTUTRE C4 are considered to be toxic or harmful at the levels present in the timber.
