Term: poor scrub resistance

Poor scrub resistance refers to a surface's or coating's low ability to withstand repeated cleaning or scrubbing without showing signs of wear, damage, or degradation.

In the context of paint and coatings, particularly in the painting and decorating industry, poor scrub resistance means that the paint film is easily worn away, discoloured, or damaged when cleaned with a brush, sponge, or cloth—especially with water or cleaning agents. This typically results in:

• Visible marks or streaks
• Loss of sheen or colour
• Peeling or flaking
• Thinning of the paint layer

Causes of Poor Scrub Resistance:

• Use of low-quality or low-sheen paints, especially flat or matte finishes
• Improper surface preparation before painting
• Insufficient curing time before cleaning
• Use of interior-grade paint in high-traffic or wet areas

Common Areas Affected:

• High-traffic walls (e.g., hallways, kitchens, bathrooms)
• Commercial or public spaces requiring frequent cleaning

Industry Relevance (Australia):

In Australia, paints are often rated for scrub resistance according to AS/NZS 2311 (Guide to the painting of buildings) and ASTM D2486 (Standard Test Method for Scrub Resistance of Wall Paints). Paints with high scrub resistance are recommended for areas requiring durability and easy maintenance.

Summary:

Poor scrub resistance = Paint or surface wears down quickly when cleaned → Not suitable for high-use or washable areas.
