Owatrol Oil Multi-Purpose Rust Inhibitor

Owatrol Rust Inhibitor is a high-performance, air-drying oil that stops rust, conditions paint, and protects wood. Applied directly to metal, it penetrates deep into rust, driving out moisture and air to halt corrosion. On porous wood, it seals the surface to prevent moisture damage and peeling. When added to oil or alkyd-based paints, it improves flow, adhesion, and finish without affecting drying times.

• Stops Rust in Its Tracks – Drives out moisture and air to halt corrosion
• Improves Paint Performance – Enhances flow and adhesion for oil-based coatings
• Seals & Protects Wood – Prevents peeling and moisture damage on porous surfaces

First, surfaces must be clean, dry and free from oil, grease and other surface contaminants. Remove all scale; loose and flaking rust and old paint back to a sound surface and edge and feather in any sharp edges. Surfaces exposed to chemicals (acids, alkalis or salt deposits) should be washed using copious amounts of water or steam cleaned. Severely contaminated surfaces should be cleaned using an appropriate solvent. Do not remove firm rust or clean the metal back to a bright finish.

Follow all the advice from the manufacturer before use.

Using Owatrol Oil on new clean steel- First prime new steel with a mix of 1 part Owatrol Oil to 3 parts primer. Then follow with normal paint system adding Owatrol Oil to subsequent coats as directed under ‘Mixing instructions’ below.

Using Owatrol Oil on lightly rusted surfaces- First prime the surface with a mix of 1 part Owatrol Oil to 2 parts primer. Then follow with normal paint system adding Owatrol Oil to subsequent coats as directed under ‘Mixing instructions’ below.

Using Owatrol Oil on new unpainted rusty steel- First prime the surface with a mix of 1 part Owatrol Oil to 1 part Primer. Then follow with normal paint system adding Owatrol Oil to subsequent coats as directed under ‘Mixing instructions’ below.

Using Owatrol Oil on old, severely rusted or previously coated surfaces- First, 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’ below. Note: Owatrol Oil will not lift well-bonded paint.

Applying Owatrol Oil as a Paint Conditioner- First apply paint in a normal manner. If the paint is sticky, drags, sets up too fast or does not level properly, add Owatrol Oil (stirring in well) until the paint works smoothly, easily and evenly. Allow the brush, roller or sprayer to be your guide.

Using Owatrol Oil as a Paint Conditioner for wood surfaces in sound condition- First prime any bare wood with a mix of 1 part Owatrol Oil to 2 parts primer and allow to dry. Follow with a normal paint system adding Owatrol Oil as in ‘Mixing Instructions’ below.

Using Owatrol Oil as a Paint Conditioner on damaged, soft or punky wood surfaces- First apply 2 to 4 liberal applications of Owatrol Oil wet on wet, as fast as the wood will absorb it. Do not allow Owatrol Oil to dry between applications. When the wood cannot absorb any more, wipe up any excess and allow it to dry overnight (12 hrs). Follow with a normal paint system adding Owatrol Oil as in ‘Mixing Instructions’ below to ease application and aid adhesion.

Q: How should I prepare a surface when using Owatrol Oil as a rust inhibitor?

Ans: Before applying Owatrol Oil to inhibit rust, ensure the surface is clean, dry, and free from oil, grease, and contaminants. Remove all loose rust, scale, and old paint down to a solid edge. Feather sharp paint edges, and if the surface has been exposed to chemicals like salt or acid, wash thoroughly with water or steam. For heavy contamination, use a suitable solvent.

Q: Can I use Owatrol Oil as a paint conditioner in water-based paints?

Ans: No, it is not recommended to use Owatrol Oil as a paint conditioner in water-based paints, for this purpose use Owatrol Floetrol Paint Conditioner instead.

Q: At what temperature can Owatrol Oil being applied?

Ans: Kindly ensure the temperature is between + 5°C and + 35°C. Please don’t apply it in direct sunlight or on hot surfaces.
