SA Sanitary Silicone Sealant seals junctions in kitchens, bathrooms, and shower screens where moisture leads to mould growth. Its neutral curing chemistry bonds to glass, ceramics, and stone to maintain a watertight finish in humid environments. The integrated fungicide provides long-term protection against mildew in high-use wet areas.
SA Sanitary Silicone Sealant contains an anti-fungicide to prevent mould growth. This formulation resists mildew in prolonged hot and humid environments, maintaining a clean finish in wet areas.
No, SA Sanitary Silicone Sealant cannot be painted. Paint will not adhere to the cured sealant surface. Plan your application to account for this limitation.
It adheres well to common building materials such as glass, ceramics, aluminium, masonry, stone, concrete, most metals, and many plastics. For unusual plastics or extruded gutter profiles, testing prior to full application is recommended.
This sealant has a skin time of 5-10 minutes at 25°C and 50% relative humidity, allowing for tooling. A 10mm deep bead will fully cure in 5-7 days under these conditions.
SA Sanitary Silicone Sealant is classified as hazardous, causing serious eye damage and potentially an allergic skin reaction. Wear safety glasses and gloves, and ensure good ventilation during use as it emits Methyl Ethyl Ketoxime (MEKO) while curing.

| General glazing | Offers excellent adhesion and UV resistance, suitable for window frames and glass installations. | Glaziers, Builders |
| Weatherproofing applications | Maintains integrity in various weather conditions with outstanding weatherability and ±25% dynamic joint movement. | Builders, Roofers, Masons |
Signal Word: Danger
This material is classified as Hazardous according to Safe Work Australia GHS 7, specifically causing serious eye damage and potentially an allergic skin reaction. It emits Methyl Ethyl Ketoxime (MEKO) during curing.
Wear safety shoes, overalls, and safety glasses. Use gloves; nitrile rubber gloves are suggested for intermittent contact, but users should assess suitability based on specific conditions. Always wash hands before eating, drinking, or using the toilet.
Use in a well-ventilated area to avoid breathing in vapours, particularly during the curing process when MEKO is emitted.
Store in a cool, dry, well-ventilated place, out of direct sunlight, and away from foodstuffs and incompatible materials. Storage temperature should not exceed 25°C to maintain the 12-month shelf life. Keep containers upright and closed when not in use. Dispose of material and containers according to local regulations.
Proper surface preparation is crucial for reliable adhesion and performance, preventing premature sealant failure.
Surface prep: Ensure surfaces are clean, dry, and free of dirt, grease, oil, rust, and water. Use white spirits or mechanical cleaning with a lint-free cloth. Do not use soap or detergent, as residues can compromise adhesion. For remedial work, all existing sealant must be thoroughly removed.
Primer: Optional. Some surfaces may benefit from a primer for enhanced adhesion; if a primer is used, allow it to dry completely before applying the sealant.
Surface prep: Clean as per general instructions. For specific plastics, contact Sealants Australasia for a recommended cleaning solvent to avoid surface degradation or adhesion issues.
Primer: Optional. Always test suitability on other types of plastic, including extruded gutter profiles, before full application.
