This guide is for DIY enthusiasts and trade professionals seeking a reliable, mould-resistant sealant for wet environments. The Soudal Trade Sanitary Silicone provides a fast-curing, flexible, and durable waterproof seal, making it ideal for bathrooms, kitchens, and other humid areas. Be aware that as an acetoxy-curing silicone, it may release a slight acetic acid odor during the curing process.
Acetoxy Curing Formula: Specifically designed for superior performance in warm and humid conditions, ensuring optimal sealant properties where moisture is present.
Mould-Resistant Protection: Contains properties that actively prevent the growth of mildew, contributing to a clean and hygienic appearance in bathrooms, showers, and kitchens.
Durable Waterproof Seal: Forms a flexible, long-lasting, and watertight barrier that exhibits good resistance to abrasion and common household cleaning detergents.
Excellent Adhesion: Securely bonds to a wide array of common construction materials including glass, ceramics, vitreous surfaces, painted surfaces, most acrylics, and anodized aluminum.
Fast Curing Time: Quickly forms a reliable skin and cures to a functional seal, allowing for efficient project completion and minimizing waiting periods.
Versatile Application: Ideal for jointing baths, sinks, toilets, showers, kitchen furniture, ceramic tiles, and various plumbing fixtures.
Easy to Apply: Provided in a standard 290ml tube with an integrated nozzle, facilitating precise and controlled application for neat results.
Trade-Quality Standard: Engineered to meet the demands of both professional tradespeople and advanced DIY users, ensuring high performance and reliability.
Excellent mould and mildew resistance for humid environments, promoting hygiene and aesthetics.
Forms a highly durable and flexible waterproof seal that withstands movement.
Offers good adhesion to a wide range of common sanitary surfaces, reducing the need for primers.
Fast-curing properties help speed up project completion and reduce downtime.
Resistant to common detergents and abrasion, ensuring longevity and ease of maintenance.
Suitable for both professional and DIY use, offering trade-quality results for everyone.
Acetoxy curing may produce a vinegar-like odor during the curing process, requiring good ventilation.
Not suitable for all plastics (e.g., some polycarbonates) without prior testing, or for natural stone as it may cause staining.
Requires a completely clean, dry, and grease-free surface for optimal adhesion and performance.

The Soudal Trade Sanitary Silicone excels in environments characterized by high humidity and fluctuating temperatures. Its acetoxy curing mechanism ensures the formation of a strong bond and a flexible, waterproof barrier capable of withstanding daily use and exposure to cleaning agents. The integrated mould resistance is a crucial feature, actively preventing the unsightly and unhygienic growth of mildew often found in wet areas, thus maintaining a pristine finish.
Real-World Application Examples:
Bathrooms: Effectively seals around bathtubs, shower trays, sinks, and toilets to prevent water leakage into underlying structures and inhibit mould growth in tile grout lines.
Kitchens: Provides durable seals around kitchen sinks, countertops, and splashbacks, safeguarding against water penetration and ensuring a hygienic surface.
Tiled Areas: Perfect for filling expansion joints and creating perimeter seals for ceramic tiles in wet rooms, utility areas, and any space prone to moisture.
Plumbing Fixtures: Creates watertight seals around pipes, taps, and other plumbing installations, preventing drips and leaks.
Ensure all surfaces are clean, dry, and completely free from dust, grease, old sealant residue, or any loose material. For optimal adhesion, a thorough cleaning with isopropyl alcohol or a suitable degreaser is recommended. Masking tape can be applied to either side of the joint for clean, straight lines.
Prepare Cartridge: Cut the tip of the cartridge, then screw on the nozzle. Cut the nozzle at a 45-degree angle to achieve the desired bead width, typically matching the joint size.
Load Gun: Insert the cartridge into a standard sealant gun.
Apply Sealant: Apply the silicone evenly and continuously into the joint, maintaining consistent pressure on the trigger for a smooth bead.
Tooling: Tool the sealant within 5-10 minutes of application using a specialized silicone tooling tool or a wetted finger (using soapy water) to achieve a smooth, professional finish and ensure good contact with both substrates.
The sealant will form a skin quickly, typically within 10-15 minutes. However, full cure, where it achieves maximum strength and water resistance, can take 24-48 hours depending on bead thickness, ambient temperature, and humidity. Ensure good ventilation in the area during the curing process, especially given the acetoxy-curing nature.
Adheres well to: Glass (without primer), most acrylics, ceramics, vitreous surfaces, painted surfaces, and anodized aluminum.
Not recommended for: Certain plastics (e.g., some polycarbonates, test first), natural stone (may cause staining), bituminous substrates, PE, PP, PTFE, or surfaces that bleed oils, plasticizers, or solvents. Do not use for structural glazing applications or aquariums.
Once fully cured, the seal is highly resistant to common household cleaning detergents. To maintain its appearance and prolong its mould resistance, regular cleaning of the sealed area with mild, non-abrasive cleaners is recommended. Avoid harsh chemicals or abrasive scrubbing pads that could damage the sealant surface.
