High-quality hard oil made from natural raw materials. It revives the natural structure, deepens the tint of the treated substrates and results in an open-pored, silk-matt, hard-wearing, dirt- and water-repellent surface that is largely non-yellowing. Fulfils the standard EN 71, part 3 (safety of children's toys) as well as DIN 53160 (fastness to sweat and saliva). Universal Hard Oil is suitable for absorbent interior surfaces such as floors made of wood, cork and linoleum, stairs, exterior furniture surfaces, sterling OSB boards and interior fittings. Meets the requirements of the parquet standard DIN EN 14342.
