A quick drying anticorrosive primer for use under chlorinated rubber Thickcoating or Finish. It is suitable for use over a variety of metallic surfaces, both ferrous and non- ferrous, and is recommended - over Etch primer - at the first coat of C.R. systems on galvanised steelwork. It can also be used as a sealer coat for zinc or aluminium metal sprayed components. On steelwork, it is most effective with blasting-cleaning, or very thorough hand cleaning using mechanical tools, as the method of surface preparation.

Theoretical coverage on smooth 7.55 - 12.1 m2/1 Surface 7.55 - 12.1 m2/1 (39.5 - 63.3 sq yd (gln or 6.40 - 10.25 m2/kg)
Note Chlorinated rubber coating have poor resistance to oil land solvents. Heat resistance is Poor. Do not apply to surfaces which exceed 65ºC. Not suitable for self weathering.
Brush / Roller
Ready for use. Apply an even coat direct from the container. Do not work the brush too much over the same area. It is not good painting practice to apply primer by roller because of poor control over film thickness. If it is essential to use rollers, ensure that the primer is applied evenly and not overspread.
  Thinner addition by volume Upto 25%
Recommended Thinner Chlorinated rubber Thinner
SURFACE PREPARATION 1. Blast clean steelwork to BS4232: 1967 'Second Quality' (Swedish Standard SA 2½ ) or U .S. Steel Structures Painting Council SSPC SP 10 Primer immediately after Blasting. If this is impractical both blasting and priming must be completed within the same working day and before the standard of blasting has deteriorated. Priming should be followed the next day by the first coat of thick coating. If this is impossible, 2 coats of primer should be used.

2. If blasting is impractical , chip, scrape and wirebrush mechanically of manually to remove loose millscale and rust before priming. This preparation method will give a lower standard of performance.

3. Galvanised Steel Fabricator's pretreatment must be removed with solvent washing and abrasion, followed by etching primer two pack.

PAINT SYSTEM Coat Chlorinated Rubber Metal Primer followed by Chlorinated Rubber Thick Coating and Finish to the recommended dry-film thickness.
