In environments prone to moisture and high humidity, such as kitchens, bathrooms, and other sanitary areas, mouldy sealant is a common issue that can not only cause unsightly black spots but also compromise hygiene and structural integrity. Over time, moisture buildup encourages the growth of mould, which thrives in the damp conditions often found around sinks, showers, windows, and other sealed areas. Platinum Chemicals offers a range of Mould Resistant Sealants designed to prevent mould growth, providing durable and long-lasting solutions to keep your home or business protected.

The Importance of Mould Resistant Sealants

When sealants around sanitary fittings or in high-humidity areas begin to degrade, they lose their ability to effectively seal and protect against moisture. This creates ideal conditions for black mould (Aspergillus niger) to grow, posing both a health risk and damaging the appearance of the space. Mould-resistant sealants are formulated with powerful anti-fungal properties, preventing the growth of mould and bacteria, ensuring that the areas remain clean and hygienic. Replacing old or degraded sealant with high-quality mould-resistant options is essential to maintaining a healthy environment, especially in areas where moisture is constant.

High-Performance Silicone Sealants for Sanitary Applications

Our range of mould-resistant silicone sealants includes Soudal Stay Fresh NEUTRAL and Soudal Stay Fresh ACETOXY, both specifically designed for sanitary applications. These sealants are packed with powerful anti-fungal agents that offer long-term protection against mould growth. Soudal Stay Fresh NEUTRAL is a neutral cure silicone, perfect for use in sanitary areas like bathrooms and kitchens, and it offers superior adhesion on a variety of surfaces, including PVC. Soudal Stay Fresh ACETOXY, on the other hand, is an acetoxy-cure silicone that provides strong, fast-setting adhesion on non-plastic surfaces, ideal for tiles, metals, and ceramics.

Both sealants provide long-lasting resistance to moisture and mildew, making them ideal for use in high-humidity environments. They are also food-safe, meaning they can be used in food preparation areas like kitchens and cafeterias without compromising safety.

Versatile Solutions for General Sealing Needs

In addition to specialised sanitary sealants, we offer versatile products like Soudal Silirub A and Soudal Trade Multi Purpose Silicone. These acetoxy-cure silicones are great all-rounders for general sealing and bonding applications, providing excellent adhesion to materials like glass, ceramics, metals, and wood. Their added fungicidal properties ensure that they resist mould growth in both indoor and outdoor applications, making them suitable for use in kitchens, bathrooms, and other damp areas.

However, for applications on plastics such as uPVC, Soudal Stay Fresh NEUTRAL is recommended to ensure the best results and long-lasting mould protection.

Hybrid Polymer Sealants for Maximum Flexibility

For more demanding applications, Soudal Fix All Flexi, Soudal Fix All Crystal Clear, and Soudal Fix All High Tack offer exceptional performance, thanks to their advanced SMX® Hybrid Polymer Technology. These multi-purpose sealants combine flexibility, high tack, and mould resistance, making them ideal for a variety of indoor and outdoor uses, from sanitary sealing to construction bonding. Soudal Fix All Flexi provides superior flexibility, making it ideal for areas prone to movement, while Soudal Fix All Crystal Clear offers a completely transparent finish, perfect for applications where aesthetics are important. Soudal Fix All High Tack is designed for applications requiring a strong initial bond and fast curing time, making it ideal for more industrial settings or heavy-duty sealing and bonding.

All these products offer excellent mould resistance, ensuring that even in the most demanding environments, they remain clean, hygienic, and functional.

Why Replace Mouldy Sealant?

Over time, even the best sealants can degrade due to constant exposure to moisture, leading to the growth of black mould. This not only looks unsightly but can also affect air quality, leading to respiratory issues for those exposed to it regularly. Mouldy sealant can also compromise the watertight seal around sanitary fittings, allowing water to seep into walls or floors, causing structural damage over time. Replacing old, mouldy sealant with modern, mould-resistant alternatives is essential to maintaining both the appearance and health of your space.
