Repair and restore architectural masonry surfaces
Overview
This standard is about repairing and restoring various architectural masonry surfaces by recording surface conditions, repairing and restoring in-situ units and joints.
This standard will involve interpreting information, adopting safe, healthy and environmentally responsible work practices, selecting and using materials, components, tools and equipment, minimising damage, and working within the allocated time, in accordance with organisational requirements and current statutory and legislative requirements
This standard is for people working in the occupational area of Associated Industrial Services and can be used by operatives, supervisors and managers
