• They provide a clear trail of accountability for contractors and supervisors.
• They serve as a reference for future maintenance or warranty claims.

What Does QA Record-Keeping Include?

Key documents used in painting QA record-keeping include:

1. Coating Inspection Report (I-20A): Tracks the details of the paint system used, including the type of coating, thickness, and application method.
2. Equipment Report (I-20B): Documents the condition and calibration of the tools/equipment used, ensuring that tools meet required standards.
3. Ambient and Surface Conditions Report (I-20C): Records weather conditions, substrate cleanliness, and environmental factors that can affect the outcome of the paint application.

The Role of Australian Standards in QA

In Australia, QA processes are guided by standards such as the AS3894 series, which provide detailed guidelines for testing and record-keeping relating to applied coatings.

These standards help ensure that coatings are applied in a way that will perform well under specific environmental conditions, such as high humidity or coastal exposure.

Why QA in Painting Matters

Without proper QA processes, issues like peeling, cracking, or uneven finishes can arise. QA ensures that:

• Surfaces are properly prepared before painting.
• The correct type and amount of paint are applied.
• Environmental conditions during application are suitable for optimal results.

Why is Painting Quality Assurance Important?

Painting quality assurance (QA) isn’t just about ticking boxes—it’s an important part of ensuring that your home’s paintwork is durable, aesthetically pleasing, and fit for purpose. Without QA processes and records, even the most expensive paints and professional application techniques can fail to deliver the results you expect.

Ensures Adherence to Standards

QA ensures that every stage of the painting process meets Australian Standards, such as AS3894 for site testing of protective coatings. These standards are designed to:

• Ensure the paint adheres properly to surfaces.
• Verify that the correct methods and materials are used.
• Confirm environmental conditions, like humidity and temperature, are within acceptable ranges.

Adhering to these standards reduces the risk of defects such as peeling, bubbling, or cracking, which can result from improper application or poor environmental conditions.

Supports Long-Term Durability and Performance

A well-executed QA process ensures that the paintwork can withstand environmental conditions and everyday wear and tear. This is particularly important in Australia, where homes are exposed to harsh sunlight, high humidity, and coastal salt spray in some regions. QA ensures that:

• Coating systems are suitable for the environment.
• Paint is applied with consistent thickness for durability and livability.
• Surfaces are prepared to allow for optimal adhesion.
