Product Overview

Summary: This Surface Preparation Prior to Painting Safe Operating Procedure sets out a clear, safe and consistent method for preparing substrates before coating application. It helps Australian businesses control WHS risks such as dust, chemical exposure and working at heights, while also lifting coating quality, durability and client satisfaction.

Surface preparation is one of the most critical stages in any painting or coating project, directly affecting both safety and long-term performance. Poorly managed preparation can generate hazardous dust, involve unsafe use of solvents and cleaning agents, and expose workers to slips, trips and falls or work at heights. This Safe Operating Procedure provides a structured, WHS-focused method for assessing substrates, selecting the right preparation technique, controlling hazards, and documenting each step in line with Australian regulatory expectations.

Designed for commercial, industrial and construction environments, the SOP covers preparation of common substrates including steel, concrete, masonry, timber and previously painted surfaces. It integrates practical safety controls with quality requirements, so that surface cleanliness, profile and moisture content meet coating manufacturer specifications and relevant Australian Standards. By implementing this SOP, businesses can reduce rework and coating failures, demonstrate due diligence in WHS management, and give supervisors a clear, trainable process that keeps jobs on schedule while protecting workers and surrounding occupants.

This procedure is particularly valuable for organisations managing large asset portfolios—such as councils, utilities, mining operations and facilities managers—where consistent surface preparation underpins corrosion protection, hygiene and appearance. It supports a culture of planned work, documented inspections and safe use of tools and chemicals, helping you meet your duty of care and deliver a professional finish on every job.
