Low temperature and high humidity will adversely affect application, drying and performance of any coating.

Surface Preparation

  • Ensure all surfaces are clean, dry and free from grease, oil and any other contaminates.
  • Bare steel should be free from dust, rust and scale.
  • Blast cleaning to SA 2½ is recommended. If blast cleaning is impractical, mechanical cleaning should be employed but hand cleaning does not clean the steel to the required degree.
  • Any oil or grease should be removed with solvent before de-rusting.
  • Where blast cleaning is carried out after assembly, special attention must be paid to edges, corners, nuts, bolts welds, etc.
  • Welds should, if necessary be ground and all weld spatter, slag etc. must be removed.
  • Existing painted surfaces - Surfaces should be cleaned, degreased and sanded to ensure an adequate "key" is produced.
  • Remove all loose and flaking material and treat bare areas as new substrate and prepare accordingly.
  • Apply to small test area first to ensure no reaction with conventional paints.
  • Maintenance: Remove all marine growth, oil and grease.
  • High pressure wash with fresh water.
  • Remove all loose coating and power tool clean areas of breakdown.
  • Bare areas should be spot primed to full film thickness prior to application of full coat.

Preceeding Coat

  • Directly onto base prepared steelwork or wood.
  • Can be applied to old, aged coatings including antifouling after recommended preparation.

Subsequent Coat

  • Teamac Antifouling paints or part of a specified Teamac anti-corrosive system.


  • Mix well before use.

Application Conditions

  • As dictated by normal good painting practice.
  • In confined spaces, provide adequate ventilation during application and drying.

We are presently renovating a 25year old swimming pool and need to repaint bases of steel supporting columns which are poolside and are in contact with chlorinated water. Can you recommend a suitable paint system. Grit blasting the column bases is not practical and the surface rust will need to removed by hand. Should a rust convertor be part of the paint system. Your advise would be appreciated.


Assuming the steel columns are clean, dry, sound and prepared as detailed in the technical data sheet this primer could be used.

Then two coats of Teamac Chlorvar Chlorinated Rubber Paint applied.

Preparation of steel by blasting to SA2.5 or mechanical means is required.

Teamac Rust Converter could be used.

I'm repainting a grp canal cruiser during November and December out in the open in the UK. Can I use this primer and the anti fouling paint in temperatures down to freezing?


No, the temperature needs to be about 5-10 degrees, you will get moisture entrapment if you try and paint it in those conditions.

questions David on 2019-10-09 15:29:10

Hi, I'm looking for a suitable primer for a small dinghy I am building from plywood. Parts will be bare plywood and parts will be epoxy glassed. The boat will live most of its life indoors, three days in water at a time max. Does the Metaclor level out when brushed on? Also can you recommend a topcoat.


We would instead recommend 2 coats of Teamac P101 High Performance Finish are applied directly to the plywood for this application.

questions William Elliot on 2019-09-16 18:19:56

I have a series of metal sumps which will be immersed in water for around 10 weeks only. The sumps have a basic metal primer applied to prevent when dry and exposed to the air. Can you recommend a product to apply over the primer to give a waterproof seal only. The sumps will not be seen and so the finish does not have to be perfect, but they do need to be waterproofed to ensure nor rust develops. I hope you can recommend a product. (Something off the shelf that I can get quickly). Thanks in advance.


Teamac Metaclor Underwater CR Primer followed by 2 coats of Teamac Chlorvar Chlorinated Rubber Paint would be suitable for this application as long as the existing primer is compatible with these products. You can either send our Technical Team the data sheet for the primer used so they can make an assesment or you can carry out a test area with the above products before full application to ascertain compatibility.

questions David Howie on 2019-07-23 17:08:35

Hi, I'm painting shipping container roofs with Chlorinated Rubber Paint, which will be the original paint used on most of them. The roofs are rusty, which will be prepared with wire brush. Would this be suitable primer prior to topcoat of Chlorinated Rubber?


If corrosion protection is the key factor here we would suggest you may be better considering Bradite CR Anti-Corrosive Primer in this instance.

questions Robert Lyall on 2019-05-16 14:16:37

Can I use a rust converter on the steel before priming with Metaclor Underwater Primer?


Yes, Teamac Rust Converter can be applied before application of Teamac Metaclor Underwater CR Primer.

questions john harwood on 2019-01-23 19:52:19

I have a bare steel haul out rail trolley for small boats. made from 100mm x 50mm channell.this will be submerged for each tide and then exposed to air. Please recommend suitable base and topcoat colour is not a critical. 15 Mtrs Linear run of steel. Number of coats to give good protection ? Thank You Supplier in Poole Dorset Area


Our suggestion for this would be to prepare the steel and then apply 2 - 3 good coats of Jotun Jotamastic 87 directly to the surface. A surface tolerant, high build primer, mid coat and finish coat product providing long lasting protection in atmospheric and immersed environments. Can also be applied at sub zero surface temperatures.

Question: I have an old galvanised metal tin bath which i want to put plants and a couple of goldfish in. Will this product seal the bath and will it be fish safe. Thanks

We would recommend thorough cleaning down with Scotch Brite pads to remove all loose and flaking materials, contamination, dirt, grease, etc. and then prime with 1 coat of Teamac 2 Pack Zinc Phosphate Primer followed by 2 coats of Teamac P101 2 Pack Polyurethane Topcoat.
