Using Owatrol Oil as a Rust Inhibitor

by Owatrol UK Ltd

Owatrol Oil is a product that wears many hats; it is a rust inhibitor, a paint conditioner and it also helps adhesion of finishes.

Owatrol Oil is a versatile, highly penetrating air drying oil and when used as a rust inhibitor, it provides a tough, flexible finish, driving out excess moisture and air; displacing it from rusted metal, stopping rust from doing any more damage.


Using Owatrol Oil as a rust inhibitor


Owatrol Oil penetrates deep, through the rusted metal to the good metal underneath, isolating it and protecting it from further rusting.

As it is a penetrating oil it can be used directly on the rusted surfaces. However, be sure to remove any loose flaking rust, paint, grease or any other contaminants before applying Owatrol Oil.

  • Apply wet on wet applications of Owatrol Oil to all exposed rust until fully saturated and allow it to dry.
  • Saturation is indicated by a uniform glossy appearance to the surface when Owatrol Oil is dry.
  • Before Owatrol Oil has hardened, check the surfaces and remove rust scale and old paint loosened by the above. If needed, touch up these areas.
  • Allow to dry.
  • Next, apply a mix of 1 part Owatrol Oil to 2 parts primer and allow to dry. Then follow with normal paint system adding Owatrol Oil to subsequent coats as directed under ‘Mixing instructions’ on the Owatrol Oil product page.
