Coo-Var Hammercote Hammered Finish

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.

Mixing Instructions

Mix well before use.

Application Conditions

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

Direct to prepared metal or Rapidry Zinc Phosphate Primer.

Subsequent Coat

Hammercote Hammered Finish

Remarks

Apply By Brush: apply a thin coat briskly to the surface. Leave for 2-4 minutes before re-coating with a full coat. By Spray: do not thin. Simply apply a mist coat followed by a full coat after 2-4 minutes. When more than one coat is required (e.g. on rough surfaces), re-coat as soon as the first coat is dry – usually within 15 minutes. Any further coats by brush or spray should be applied as soon as possible but certainly within 4 hours after which time the Hammercote will have started the curing period. Heat resistant to 150°C. Full hardness is reached after several days. Do not thin Hammered Finish for spraying. Cannot be successfully coated with conventional paints.
