FAQ

What’s the difference between sanitary silicone and standard silicone sealants?

Sanitary silicone contains fungicide additives that resist mould and mildew growth, making it ideal for use in bathrooms, kitchens and other wet areas. Standard silicone may not provide the same level of protection against mould and mildew in damp environments.

What type of sealant should I use around bathroom fixtures like sinks, baths and showers?

For sealing around bathroom fixtures, a high-quality hygienic silicone such as EVERBUILD FOREVER WHITE® is recommended. It’s resistant to mould, waterproof and provides long-lasting protection in areas of high humidity.

How do I prepare surfaces before applying bathroom sealants or adhesives?

Ensure all surfaces are clean, dry, and free from dust, grease or old sealant residue. Proper preparation helps ensure optimal adhesion and long-term performance of the product. Always follow the product’s technical data sheet.

Are Sika bathroom products suitable for both renovations and new builds?

Yes, Sika’s range of adhesives, sealants and waterproofing products are suitable for both refurbishment projects and new bathroom installations.

Where can I find technical guidance for using Sika bathroom products?
