There are few places where wood is exposed to greater stresses than on cruise ships, whose wooden railings, doors and staircases are subjected to thousands of passengers, glaring sunlight and aggressive salt water on a daily basis. With its outstanding properties, this special hard oil - including after-treatment with High Solid hard oil - ensures that they survive this for years without damage. These are products that are normally used in the professional sector, for example on the Queen Mary 2. Our manufacturer uses linseed oil and wood oil stand oils of the highest quality and viscosity. They create a tough, elastic layer that allows the wood to "work" without forming blisters, scales or cracks. The surface becomes water-repellent, yet remains vapor-permeable and open-pored.

The hard oils can be used all year round indoors and outdoors for floors and stairs as well as for the maintenance of walls, ceilings, patios and furniture. They are also suitable for untreated cork and terracotta - Hard Oil Special is also suitable for natural stone.
