Baked on Oil Finish
Baked on Oil Finish
Nothing beats cast iron for permanence, raw strength and beauty. However, not everyone likes the initial orange rusting period and waiting one to two years for the natural patina to develop. Trench Drain System’s Baked on Oil Finish (BoOF) is a pre-rusting process that seals in a natural chocolate brown weathered appearance that bypasses the initial rusting stages.
When exposed to the elements, raw cast iron will quickly (sometimes within hours) turn from silver to an orange-brown as the exterior weathering oxidation begins. Over time, a stable oxide exterior patina forms that result in the dark brown appearance we are accustomed to seeing on old cast iron commonly seen in streets and parking lots. The complete natural process does require time and the unsightly rust runoff can potentially stain nearby surface areas.
There are many factors that determine how long it will take for the color to change to a rustic brown patina. One factor is regional conditions in which inland areas don’t see the harsh salt water that is experienced in coastal areas. Other climate conditions such as rain and snowfall amounts also play a role in how quickly oxidation occurs.
