Instruction - Repair of hot-dip galvanised surfaces
What is taught?
In this course, you will learn all the relevant basics and practical steps for professional repair of hot-dip galvanised surfaces. The contents cover the entire process - from the Avoidance of damage about the Recognition and assessment of repair requirements up to the standardised repair in accordance with DIN EN ISO 1461. You will receive practical instructions for the Preparation of the substrate, which Processing conditions, which Application of zinc paste (e.g. LZ-09) and the Step-by-step documentation of a repair process.
Topics at a glance:
- Significance of surface quality and typical damage patterns (scratches, flaking, white rust)
- Protective measures during transport, storage and installation
- Standardised repair: limit values and permissible methods
- Substrate preparation: sanding, degreasing, cleaning
- Processing zinc paste: application, layer thickness, drying
- Influence of temperature and weather on quality
- Practical repair example with before and after comparison
