Marine Oil is a versatile, highly penetrating air drying oil that can be used alone or added to paint. Used alone it provides a tough, flexible finish, driving out excess moisture and air; displacing it from rusted metal, so stopping rust. Used alone on porous wood surfaces it will saturate and protect the wood from damage caused by moisture and prevent paint from peeling.
Added to any oil or alkyd based coatings Marine Oil will give increased wet edge time, improved flow ability, greater adhesion and unlike damaging thinners, will maintain the inherent quality of the paint without affecting its appearance or drying times.
Using Marine Oil as a rust inhibitor
Marine Oil penetrates through rusted surfaces to the sound metal below, isolating it and protecting it from further rusting. As it is a penetrating oil it can be used directly on the rusted surfaces – it drives out moisture and air and stabilises the metal to protect it from future damage.
On brand new metal surfaces, use Owatrol’s AP 60 instead. If you are looking for a high gloss rusted finish you can also overcoat the surface with Deks Olje D2 high gloss clear oil.
Using Marine Oil to aid adhesion
Marine Oil leaves a bonding film on all surfaces it is used on which maintains the natural look of the surface but allows enhanced adhesion, making it perfect as a foundation for primers or finishing coats. It gives excellent adhesion including on galvanised steel, aluminium, zinc, wood and more. It allows paint to be applied directly to firm rust and is heat resistant up to +175°C.
Using Marine Oil as a paint conditioner
Marine Oil can be mixed into oil-based paints as a paint conditioner when several great benefits. Firstly, it gives the paint rust inhibiting properties and helps prevent rust on painted surfaces – even when rust is already present. It also improves the flow and workability of the paint, maintaining the ‘wet edge’ for longer and reducing brush and roller marks. Finally, it also gives the paint a better viscosity which allows painting work to be carried out in more extreme cold, heat and windy conditions, perfect for the marine environment. Unlike damaging paint thinners it does not alter the inherent qualities or the finish of the paint.
Please note that if you are looking for a product to give this effect but for water-based paints then please use Floetrol instead as it is designed for use in any water-based paint whereas Marine Oil is for use in oil-based paints.
Using Marine Oil for wood impregnation
When used on dry wood surfaces Marine Oil saturates the wood and protects it from damage caused by moisture. It also helps to prevent paint from peeling and protects metal parts such as hinges and latches from corrosion.
Ideal Uses for Marine Oil
- Priming galvanised surfaces with no need for weathering or pickling
- Preventing further damage in heavily rusted surfaces on hulls and tanks
- Improving paint flow when working in cold environments
- Preventing peeling paint on wood surfaces
- Protecting metal parts on wood surfaces hinges and latches
- Assuring better adhesion of finishes
Surface preparation when using Marine Oil as a rust inhibitor
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, alkali 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.
Surface preparation when using Marine Oil as a paint conditioner
First prepare the surface as per the instructions on your paint can. In addition, if not asked to, ensure that you remove all loose and flaking material and treat any organic growth with fungicidal solution or a mix of 1 part water to 1 part chlorine bleach (allow bleach solution to sit for 15 minutes), rinse thoroughly and allow to dry.
Applying Marine Oil as a Rust Inhibitor
Using Marine Oil on new clean steel
First prime new steel with a mix of 1 part Marine Oil to 3 parts primer. Then follow with normal paint system adding Marine Oil to subsequent coats as directed under ‘Mixing instructions’ below.
Using Marine Oil on lightly rusted surfaces
First prime the surface with a mix of 1 part Marine Oil to 2 parts primer. Then follow with normal paint system adding Marine Oil to subsequent coats as directed under ‘Mixing instructions’ below.
Using Marine Oil on new unpainted rusty steel
First prime the surface with a mix of 1 part Marine Oil to 1 part Primer. Then follow with normal paint system adding Marine Oil to subsequent coats as directed under ‘Mixing instructions’ below.
Using Marine Oil on old, severely rusted or previously coated surfaces
First apply wet on wet applications of Marine 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 Marine Oil is dry. Before Marine 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 Marine Oil to 2 parts primer and allow to dry. Then follow with normal paint system adding Marine Oil to subsequent coats as directed under ‘Mixing instructions’ below.
Note: Marine Oil will not lift well bonded paint.
Applying Marine Oil as a Paint Conditioner
First apply paint in normal the manner. If the paint is sticky, drags, sets up to fast or does not level properly add Marine Oil (stirring in well) until the paint works smoothly, easily and evenly. Allow the brush, roller or sprayer to be your guide.
Using Marine Oil as a Paint Conditioner for wood surfaces in sound condition
First prime any bare wood with a mix of 1 part Marine Oil to 2 parts primer and allow to dry. Follow with normal paint system adding Marine Oil as in ‘Mixing Instructions’ below.
Using Marine Oil as a Paint Conditioner on damaged, soft or punky wood surfaces
First apply 2 to 4 liberal applications of Marine Oil wet on wet, as fast as the wood will absorb it. Do not allow Marine Oil to dry between applications. When the wood cannot absorb any more wipe up any excess and allow to dry overnight (12 hrs). Follow with normal paint system adding Marine Oil as in ‘Mixing Instructions’ below to ease application and aid adhesion.
Topcoat: As required – normally 5 %-20 % by volume.
Undercoat: up to 30 % by volume.
Primer: up to 50 % by volume.
The above is meant as a guide only. Conditions of application, porosity of surface etc. will dictate the amount of Owatrol Oil to be mixed into the paint.
Clean all tools and equipment with white spirits while still wet. If allowed to dry, remove with paint stripper. Store and maintain equipment as directed by manufacturer.
NOTE: Any rags, steel wool etc soaked in Marine Oil may spontaneously catch fire if improperly discarded. Rags, steel wool etc must be saturated with water after use or placed in a sealed, water filled metal container, before disposing with household waste.
Do not mix or overcoat Marine Oil with paints containing hot solvents i.e. Xylene, 2 part coatings, chlorinated rubber etc. – for these type of paints use Owatrol CIP instead. Do not use Marine Oil as a paint conditioner in water-based paints, for this purpose use Floetrol instead – Owatrol’s water-based paint conditioner.
Things to Remember
- Cover everything you do not wish to paint.
- Apply between + 5°C and + 35°C.
- Do not apply in direct sunlight or on to hot surfaces.
- Test for compatibility when adding Marine Oil to paint.
