CIP (Corrosive Inhibiting Primer) is a rust inhibiting primer. Suitable for finishing with both single and 2-pack paints and finishes. It contains the anti-corrosive properties of Owatrol Oil which enable it to stabilise the surface. It does this by penetrating deep into the substrate, driving out excess moisture and air to form a solid stable layer.
CIP is easy to use and does not require sand or shot blasting first. It can be used on new and rusted surfaces – both interior and exterior and is fine for use on horizontal and vertical surfaces.
It will not dissolve or break down when even high solvent paints and finishes (urethane, epoxy, chlorinated rubber, synthetic, etc.) are applied to it. Making it perfect to use as a primer for 2-pack paints. The brick red pigmentation also provides enhanced protection and film-forming qualities.
With Owatrol’s CIP, sand or shot-blasted surfaces do not require immediate priming as a light rust coating will not affect its performance or the final result.
CIP’s enhanced corrosion protection and strong surface make it perfect for use in extreme climatic conditions such as in the marine environment and in tropical areas and it has excellent chemical resistance too. Its excellent adhesion means that it also performs exceptionally well on clean, bright steel – typically a difficult surface to coat.
Ideal uses for CIP rust inhibiting primer
- Outstanding for high performance in severe conditions such as marine or tropical environments
- Resisting corrosive fumes
- Protecting motor vehicles
- Avoiding rusting on construction equipment
- Protecting ballast tanks of ships
- Inhibiting rust development on everyday items such as railings and gates
- Perfect protection where a high resistant paint or two-pack finish is necessary
- Priming steel superstructures
- Outstanding adherence on clean bright steel
Restrictions
- Caution if using Novol Protect 360 Epoxy.
- One coat CIP maximum.
- Always check for compatibility.
Surface Preparation
General Directions
- Surfaces must be clean, dry, and free from oil, grease and other surface contaminants.
- Surfaces exposed to chemicals (acids, alkalis, or salt deposits) should be washed using copious amounts of water or steam cleaned. Allow to fully dry.
- Severely contaminated surfaces should be cleaned using an appropriate solvent.
- Remove all mill glaze from new metal.
- Feather in any sharp edges.
- Round off any sharp edges to a 2mm radius.
- All surfaces cleaned with water or steam cleaned should be allowed to dry a minimum of 24 hours before applying CIP, except for galvanised surfaces treated with Owaphos. Galvanised surfaces treated with Owaphos should be coated within 8 hours.
- Do not remove firm rust.
New or Bright, Clean Metal:
- Sand surface with 80 grit abrasive (nothing finer) to form a key.
- Thoroughly dust off.
- Note: New metal is classed as pickled stock or metal that has been sandblasted to remove any mill glaze and is not rusty. Alternatively for new or bright clean metal use PID 60.
Rusted/Oxidised Surfaces:
- Remove all loose and flaking rust
- Thoroughly dust off.
- Note: For excessively and deeply rusted surfaces apply a coat of Owatrol Oil.
Previously Coated Surfaces:
- Remove all loose, flaking, rust and paint.
- Feather in any sharp edges.
- Thoroughly dust off.
- Apply a coat of Owatrol Oil to the entire surface.
Galvanised (Zinc) Surfaces:
New:
- Treat with Owaphos to passivate the surface.
- Allow to fully dry or dry with a cloth (dabbing action only), forced air etc. DO NOT wipe dry.
- Note: It is imperative that the prepared surface is coated within 8 hours.
Weathered:
- Clean thoroughly with hot soapy water, Pura-Trol, steam clean or use a non-oxidising agent e.g. Acetone.
- Allow to dry a full 24 hours.
- Note: Weathered surfaces are those deemed to have been exposed to the elements for longer than 12 months. Any galvanised
surface 12 months or under should be treated as new.
Application Tools
- Brush
- Roller
- Spray (Airless Sprayer 0.4mm x 80° @1850 to 2000psi (128 to 138 bars)).
If applying Owatrol CIP by spray, adjust the product by adding 5% to 20% Owatrol Oil depending on nozzle size and type to bring it to the desired viscosity.
Application of CIP Corrosive Inhibiting Primer
- Apply a thin layer of Owatrol CIP.
- DO NOT over apply. Owatrol CIP is a primer and its purpose is to penetrate the surface, not mask it.
- See “Application Tools” when applying by spray.
Restrictions
Due to the aggressive nature of some automotive paints combined with their tough, hard and inflexible finish it is recommended that a test is carried out with Owatrol CIP to ensure compatibility before commencing with the entire project.
While Owatrol CIP followed by an automotive paint may be applied to New and/or Brightly Cleaned Metal the use of PID60 is recommended for these surfaces.
Clean Up
Clean all tools and equipment with white spirit while still wet. If allowed to dry, remove with paint stripper.
NOTE: Any rags, steel wool etc. soaked in CIP 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.
Things to Remember
- Cover everything you do not wish to paint.
- Apply between 5°C (41°F) and 35°C (95°F).
- Do not apply in direct sunlight or to hot surfaces.
- Do not apply if cold and/or wet weather is expected within 24 hours.
- Stir product thoroughly before and during application.

Primes bare metal and rusted areas really well. Used to protect against corrosion of roof rail channels where water gathers on my narrowboat. Recommended to a boating colleague too.

Worked perfectly for the badly rusted and pitted deck in my bow lockers, highly recommended
