4 For temporary protection, if required, use a suitable PREPARATION: shopprimer. All damage of shopprimer and contamination from storage and fabrication should be thoroughly cleaned prior to final painting. For repair and touch-up use HEMPADUR PRIMER. Other metals and light alloys: Thorough degreasing and removal of any salty contamination. Abrasive sweeping to create a suitable dense anchor profile. Repair and maintenance: Remove oil and grease, etc. with suitable detergent. Remove salt and other contaminants by (high pressure) fresh water cleaning. Clean damaged areas thoroughly by power tool cleaning to St 3 (minor areas) or by abrasive blasting to min. Sa 2, preferably to Sa 2 . Improved surface preparation will improve the performance of HEMPADUR PRIMER 15300.

5 Feather edges to sound intact areas. Dust off residues. Touch up to full film thickness. On pit-corroded surfaces, excessive amounts of salt residues may call for high pressure water jetting, wet abrasive blasting, alternatively dry abrasive blasting, high pressure fresh water hosing, drying, and finally, dry abrasive blasting again. APPLICATION Use only where application and curing can proceed at temperatures above 10 C/50 F. CONDITIONS: The temperature of the paint itself should preferably be 15 C/59 F or above to secure proper application properties. In confined spaces provide adequate ventilation during application and drying. Apply only on a dry and clean surface with a temperature above the dew point to avoid Condensation. SUBSEQUENT HEMPADUR qualities, HEMPATHANE qualities or according to specification.

6 COAT: REMARKS: Weathering/ The natural tendency of epoxy coatings to chalk in outdoor exposure and to become more service sensitive to mechanical damage and chemical exposure at elevated temperatures is also temperatures: reflected in this product . Film thickness: May be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate and may influence drying time and recoating interval. Normal range is 50-125 micron/2-5 mils. Recoating intervals: Recoating intervals related to later conditions of exposure: Minimum Maximum Surface temperature 20 C/68 F 20 C/68 F. Atmospheric Atmospheric Recoated with Medium Severe Medium Severe HEMPADUR 4 hours 8 hours None None HEMPATHANE 3 hours 6 hours 36 hours 24 hours If the maximum recoating interval is exceeded, a thin, fresh coat of HEMPADUR HB PRIMER 17300.

7 Can be applied to ensure intercoat adhesion. Alternatively, the surface can be roughened. A completely clean surface is mandatory to ensure intercoat adhesion, especially at long recoating intervals. Any dirt, oil, and grease has to be removed, with suitable detergent. Salts to be removed by fresh water hosing. Notes: HEMPADUR HB PRIMER 17300 is for professional use only. ISSUED BY: Hempel PAINTS (SAUDI ARABIA) - 1730012170SA001.
