Best Uses

Hempel Hemucryl Primer Hi-Build 18032 is formulated as a primer in water-borne paint systems on interior and exterior steelwork in mildly to moderately corrosive environments. It may also be used as a primer in water-borne paint systems on hot dip galvanized steel, aluminium, and stainless steel in a mildly corrosive environment.

Hempel Hemucryl Primer Hi-Build 18032 is especially suited for application by airless spray.

Application

Preparation For New Steel: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Abrasive blasting to the cleaning degree specified for the final coating system, usually Sa 2½ (ISO 8501-1:2007). Apply immediately after cleaning. All damage of shop primer and contamination from storage and fabrication should be thoroughly cleaned prior to overcoating.

Preparation For Repair and Maintenance: Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Remove rust and loose paint by abrasive blasting or power tool cleaning to St 3 (ISO 8501-1:2007) (minor areas) before recoating. For repair and touch-up use: Hempel Hemucryl Primer Hi-Build 18032.

Preparation For Aluminium: Very careful degreasing, followed by high pressure fresh water cleaning to remove all salts and other contamination. Any anodizing must be completely removed. Thorough sand papering or abrasive sweeping with mineral abrasives is recommended. Cast aluminium is recommended to be abrasive swept to a uniform, evenly grey appearance.

Preparation For Hot Dip Galvanized Steel: Wet rubbing/grinding with ammonia - water 1:20, followed by fresh water hosing. In case this method is not feasible, the procedure described for stainless steel may be used.

Preparation For Stainless Steel: Very careful degreasing followed by fresh water hosing to remove all contamination.

Use only where application and curing can proceed at temperatures above: 10°C/50°F. Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. Relative humidity  during application and drying: maximum 80%, preferably 40-60%. Good ventilation during application and drying is necessary. During drying, it is of utmost importance that sufficient ventilation is covering all parts of the surfaces painted. Ventilation requirements to remove the water vapours liberated during application and drying are approx. 75 m3/litre of paint at 20°C/68°F. (Relative humidity of the air supply 40%)
