Protite 75ml Mould Defender Paint Additive – Long-Lasting Protection | Australia

Invisible Protection Against Mould — Built Right Into Your Paint

Mould is one of the most persistent and frustrating problems in Australian homes — particularly in bathrooms, kitchens and laundries where moisture, warmth and poor ventilation create the perfect conditions for it to thrive. Repainting over mould-affected surfaces without addressing the root cause is a short-term fix at best. The Protite Mould Defender Paint Additive takes a smarter approach, allowing you to build powerful, long-lasting mould inhibition directly into whatever coating you’re already applying — no extra steps, no visible change to your finish.

Whether you’re a professional painter, a property manager refreshing a rental, or a homeowner tackling a bathroom renovation, Mould Defender integrates seamlessly into your existing workflow. Simply add it to your paint, grout, mortar or coating of choice, mix it through, and apply as normal. The result is a treated surface that actively resists mould growth for the long term — without looking or feeling any different to an untreated surface.

Key Highlights

• Broad Compatibility Across Multiple Products — Mould Defender isn’t limited to paint alone. It can be added to grout, mortar, adhesives, timber oils, timber stains and textured coatings, making it one of the most versatile mould inhibiting additives available for both interior and exterior applications.
• Exceptional Coverage — 75ml Treats 15 Litres — A single 75ml bottle is enough to treat up to 15 litres of paint or coating, delivering outstanding value and making it a cost-effective choice for both small touch-up jobs and full room repaints.
• Long-Lasting Mould Protection — Unlike surface sprays that wash off or wear away quickly, Mould Defender is incorporated directly into the coating itself, providing durable, long-term protection that stays active well beyond what topical treatments can offer.
• No Change to Appearance or Texture — The additive is specifically formulated to be invisible once mixed — it won’t affect the colour, sheen, consistency or texture of your paint or coating, ensuring a professional finish every time.
• Ideal for High-Moisture Areas — Purpose-designed for environments where mould is most likely to take hold, including bathrooms, kitchens, laundries, basements and other areas prone to condensation, steam and humidity.
• Easy to Use — Simply measure the correct amount, add it to your chosen product, stir thoroughly and apply as you normally would. No specialist equipment, no complicated preparation — just straightforward mould protection built into every coat.
• Suitable for DIY and Trade Applications — Whether you’re a homeowner refreshing a bathroom or a professional painter working on a large residential or commercial project, Mould Defender is practical, efficient and effective at any scale.

Perfect For

The Protite 75ml Mould Defender Paint Additive is the ideal solution for homeowners, renovators, property managers, builders and professional painters dealing with mould-prone surfaces across Australia. It’s particularly well suited to bathroom and ensuite repaints, kitchen splashback areas, laundry walls and ceilings, grout lines in wet areas, timber decking and fencing in shaded or humid environments, and any surface in a high-moisture or poorly ventilated space. It’s also an excellent preventative measure when painting newly constructed wet areas, ensuring mould resistance is built in from day one rather than dealt with as a problem later.
