Burnishing Paint
Understanding the Causes and Solutions
Definition
Burnishing refers to the unwanted development of shiny or polished spots on painted surfaces due to repeated rubbing or scrubbing (easier to spot on darker paint colours).
Basic Information
Burnishing typically occurs when a low-sheen or matte paint is used in areas prone to contact or cleaning. The constant friction wears down the paint's surface, leading to shiny patches. While it doesn't usually affect the protective qualities of the paint, it can compromise the uniform appearance and lead to a patchy look over time. This problem is most commonly seen in high-traffic areas, like hallways, doors, or around light switches, where frequent contact occurs.
Common Causes
Inappropriate Paint Choice: Using matte or low-sheen paints in areas where frequent cleaning or contact occurs can make surfaces more vulnerable to burnishing.
Excessive Cleaning: Aggressive scrubbing or cleaning with abrasive materials can wear down the paint's surface, causing it to burnish.
Frequent Contact: High-traffic areas, like hallways or doors, are often touched or brushed against, increasing the chance of burnishing.
Low-Quality Paint: Paints that lack durability or don't have good scrub resistance are more prone to burnishing.
Progression
Over time, burnishing can make the affected areas appear uneven and glossy in contrast to the surrounding surfaces. This is especially noticeable on walls with a flat or matte finish. If ignored, the burnished spots may become more widespread, especially in areas that are frequently touched or cleaned.
Solution
Use Durable Paint: Opt for higher-sheen paints like satin or semi-gloss in high traffic areas, as they are more resistant to burnishing and are easier to clean without damage.
Clean Gently: When cleaning painted surfaces, use a soft cloth or sponge and mild cleaning agents to avoid wearing down the paint.
Limit Contact: Try to minimize friction in vulnerable areas by using protective covers or reducing frequent physical contact.
Touch Up Paint: For minor burnished spots, repainting the affected areas with a more durable, high-quality paint may restore the original look. Ensure proper surface preparation for better adhesion and longevity.
