Product Overview

Summary: This Interior and Exterior Drywall Applications SOP provides a clear, step‑by‑step method for installing, finishing and repairing plasterboard in both internal and external environments while maintaining strong WHS compliance. It helps construction businesses standardise quality, control key site hazards such as dust, manual handling and work at height, and deliver consistent, defect‑free finishes across every project.

Interior and exterior drywall work is a core activity on Australian building sites, yet it is also a common source of safety incidents, re‑work and client complaints. This Safe Operating Procedure sets out a best‑practice, WHS‑aligned approach to planning, installing and finishing plasterboard systems in a way that controls key risks while also driving consistent workmanship. It covers the full workflow – from pre‑start inspections, material handling and substrate preparation through to fixing, jointing, sanding, sealing and site clean‑up for both internal linings and external soffits or weather‑resistant board systems.

The SOP is designed to help builders and contractors meet their primary duty of care under WHS legislation while protecting margins and reputation. By clearly defining roles, equipment requirements, hazard controls and quality checkpoints, it reduces variation between crews, shortens onboarding time for new workers and provides a defensible process if your practices are ever scrutinised by regulators, principal contractors or clients. Whether you are working on residential units, commercial fit‑outs or large‑scale developments, this document gives your team a clear, repeatable method to deliver safe, compliant and high‑quality drywall installations on every job.
