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.

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.

Application

Mixing ratio
Stir well before use. Viscosity may increase during storage.

Thinner
Hempel’s Thinner 08080

Cleaner
Hempel’s Thinner 08080

Application method

Tool	Thinning max vol.	Application parameters
Airless spray	5%	Nozzle pressure: 200 bar [2900 psi], Nozzle orifice: 0.013-0.019″
Brush/Roller	5%	Not Applicable

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 range	Dry film thickness	Wet film thickness	Theoretical spreading rate
Low	60 micron [2.4 mils]	126 micron [5.0 mils]	8 m²/L [326 sq ft/US gal]
High	120 micron [4.8 mils]	251 micron [10 mils]	4 m²/L [163 sq ft/US gal]
Recommended	80 micron [3.2 mils]	168 micron [6.7 mils]	6 m²/L [244 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 80 micron [3.2 mils] at standard conditions, see Hempel’s Explanatory Notes for details.

---

Overcoating
Hempel’s specification supersedes any guidelines indicated in the overcoating table.

Quality name	20°C [68°F]
Atmospheric medium
Hempel’s Speed-Dry Alkyd 43141	Min 60 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

Dry film thickness	GWP (Global Warming Potential)
1 µm / 1 mil	8.9 g CO₂e/m² / 0.046 lb CO₂e/ft²

The carbon footprint is for 1 square meter / square foot of surface area with a dry film thickness of 1 micron / mil.
The scope includes raw materials, in-bound transport to the Hempel factory, Hempel manufacturing processes, and any Volatile Organic Compounds emitted during and after the application of the product.
It is calculated based on the standard shade defined in this PDS. Values may vary with shade.
