biopin Natural Hard Oil

bio pin Natural Hard Oil is a breathable and water-repellent primer and finish for interior surfaces with heavy wear. The oil particularly enhances the pressure, wear and knock resistance of softwoods and cork. It consolidates the surface whilst retaining its elasticity. It slightly deepens the colour of the wood and highlights the grain. When completely dry bio pin Natural Hard Oil is suitable for contact with foodstuffs.

Area of application

bio pin Natural Hard Oil is suitable as a primer and finish for untreated work surfaces in kitchens, wooden floors and other interior woods with heavy wear. It can also be used as a primer for untreated cork floors and for the treatment of unglazed clay tiles.
