Toning is made with varnish or colored oil (impregnation). Preference is given to the imported compositions of Loba, Bona, Osmo, Neolux. Glacks are painted only the upper surface of the parquet, not absorbed deeply, but at the same time reliable. The amount of oil for tinting depends on the breed of the processed wood, so coniferous rocks absorb it much less than deciduous. In some cases, tinting is performed several times for better color saturation, only a specialist can determine this.
