Surface preparation

Cleanliness

  • Remove oil, grease and other contaminants by suitable detergent cleaning.
  • Remove salts, detergents and other contaminants by high pressure fresh water cleaning.

New build

  • All damage of shopprimer and contamination from storage and fabrication should be thoroughly mechanically/chemically cleaned prior to final painting.
  • Abrasive blasting to min. Sa 2½ (ISO 8501-1) / SP 10 (SSPC).
  • Remove dust, blast media and loose materials.
  • The surface must be dry and clean prior to application.

Maintenance and Repair

  • Spot abrasive blasting to min. PSa 2 (ISO 8501-2) / SP 6 (SSPC).
  • Minor areas can be cleaned by power tool to St 3 provided the surface is roughened and not polished.
  • Remove dust, blast media and loose materials.

Consult Hempel’s separate Surface Preparation Guidelines for more details.

If brush or roller application is used, more coats will be necessary to achieve the specified dry film thickness. Spray data are indicative and subject to adjustment. Pressure is for a material temperature of 20°C [68°F].


Film thickness

Specification Dry film thickness Wet film thickness Theoretical spreading rate
Low 40 micron [1.6 mils] 80 micron [3 mils] 12 m²/L [490 sq ft/US gal]
High 120 micron [4.7 mils] 250 micron [10 mils] 4.1 m²/L [170 sq ft/US gal]
Recommended 60 micron [2.4 mils] 120 micron [5 mils] 8.2 m²/L [330 sq ft/US gal]

Product may be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate, drying and curing time and overcoating interval. For best performance, avoid excessive film thickness.


Application conditions

  • Surface temperature must be above 5°C [41°F] during application and curing.
  • To avoid condensation, apply on a clean and dry surface with a temperature that is at least 3°C [5°F] above the dew point.

Relative Humidity

  • Relative humidity must be below 90% during curing.
  • Relative humidity must be below 90% during application.

Drying and overcoating

Product compatibility

  • Previous coat: According to Hempel’s Specification.
  • Subsequent coat: According to Hempel’s Specification.

Drying time

Surface temperature Surface dry min Hard dry min
20°C [68°F] 15 60

Determined for dry film thickness 60 micron [2.4 mils] at standard conditions, see Hempel’s Explanatory Notes for details.


Overcoating

Quality name 20°C [68°F] Atmospheric medium
Hempatex Enamel 56360 Min 15 min / Max 24 h
Hempathane HS 55610 Min 30 min / Max Ext

Overcoating times are indicative for products of the same generic chemistry. Consult Hempel’s specification for more information.

Drying conditions

  • To obtain the drying time stated, it is important to maintain sufficient ventilation during application, drying and curing.

Overcoating details

  • If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion.
  • The surface must be clean before overcoating.

Other remarks

  • Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.

Storage

Shelf life

Ambient temperature Product
25°C [77°F] 36 months

Shelf life from date of production, when stored in original, unopened containers. Thereafter, the product quality must be re-inspected. Storage at elevated temperatures may reduce shelf life. For advice, please consult Hempel.


Carbon Footprint
