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

• 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 may be hand or power tool cleaned instead of abrasive blasting.
• Remove dust, blast media and loose materials.

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

Application method

Tool	Thinning max vol.	Application parameters
Airless spray	5%	Nozzle pressure: 175 bar [2500 psi]

                                   Nozzle orifice: 0.017-0.021"            |

| Air spray | 15% | Not Applicable. |
| Brush | 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	Dry film thickness	Wet film thickness	Theoretical spreading rate
Low	50 micron [2.0 mils]	120 micron [4.8 mils]	8.3 m²/L [338 sq ft/US gal]
High	125 micron [5.0 mils]	300 micron [12 mils]	3.3 m²/L [134 sq ft/US gal]
Recommended	100 micron [4.0 mils]	240 micron [9.6 mils]	4.2 m²/L [171 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

• 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.

Application remarks

• Two coats of the topcoat may be necessary to obtain full hiding power.

---

Drying and overcoating

Product compatibility

• Previous coat: None or according to Hempel’s specification.
• Subsequent coat: None or according to Hempel’s specification.

Drying time

Surface temperature	Surface dry	Hard dry
-10°C [14°F]	2½ h	9 h
0°C [32°F]	1½ h	4½ h
20°C [68°F]	¾ h	1½ h
40°C [104°F]	½ h	1 h

Determined for dry film thickness 100 micron [4.0 mils] at standard conditions, see Hempel’s Explanatory Notes for details.

Overcoating

Quality name	-10°C [14°F]	0°C [32°F]	20°C [68°F]	30°C [86°F]
Hempatex HI-Build 46410	Min 26 h	12 h	4 h	3 h
	Max Ext*	Ext*	Ext*	Ext*

Ext*: Depending on the actual exposure conditions, the coated surface is overcoatable for an extended period of time. Contact your local Hempel representative for advice.
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

• The surface must be dry and clean prior to application.

---

Other remarks

• Hempatex qualities are thermoplastic, therefore prolonged direct pressure at temperatures above 40°C [104°F] may cause film indentations.
• Hempel’s Specification supersedes any recommendations given in the Product Data Sheets.

Storage

Shelf life

Ambient temperature	Product
25°C [77°F]	60 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	1 µm	1 mil
GWP	9.2 g CO₂e/m²	0.048 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.
