Frequently Asked Questions
What is a sanitary silicone for?
Sealing the joints around basins, baths, showers, toilets, kitchen benches, and splashbacks. It is a mould-resistant silicone that stays flexible in wet areas. The range includes Adheseal S100 and S350, Bostik 6S, Mapei Mapesil AC, Pasco 912, and Sealants Australasia SA Sanitary.
Which sanitary silicone should I buy?
They all do the same job: seal a wet-area joint and resist mould. The differences are brand, colour, and slight chemistry. Adheseal S100 and S350 and Bostik 6S are the common picks for kitchens and bathrooms. Mapesil AC also covers pools. Pick the brand you trust and the colour that matches the room.
Can I use a sanitary silicone to fix a leaking pipe?
No. It seals a surface joint. It is not a pipe repair, a pressure seal, or a substitute for the right fitting. Fix the mechanical joint first, then seal the visible gap with the silicone.
Is a sanitary silicone the same as a structural silicone?
No. Sanitary silicone is for flexible joints in wet areas. Structural silicone bonds glass and panels in glazing. They are not interchangeable. If the job is structural, use the structural product.
Why are there so many options?
Brand preference, colour, and small differences in flexibility and mould resistance. Most jobs need one tube. Pick the one that suits your substrate, your colour, and your budget.
I see some of these in your caulking range too. Are they different products?
No, they are the same product. A sealant does more than one job, so it can appear in a few categories. Buy it from whichever you are shopping in; the tube is the same.
