Silicone Tile Sealants

Professional silicone sealant for tiles is essential for creating a waterproof, flexible barrier in bathrooms and kitchens. These sealants are specifically formulated to accommodate movement between tiles and sanitaryware, such as baths, basins, and shower trays. Using high-quality silicone from brands like Ardex and BAL prevents leaks and protects the structural integrity of your walls and floors. 

Choosing Your Sealant and Finish 

Selecting the right sealant depends on both the tile material and the room’s humidity levels. We offer sanitary-grade formulas with anti-mould properties to maintain a clean appearance in damp environments. For a seamless look, choose a coloured silicone that matches your grout, or opt for a clear finish to bridge the gap between different materials without a visible border. 

If you are looking for other tools and materials, we have a range of tile adhesives, tile primers and tile spacers.  

FAQs About Silicone Sealants for Tiles 

Is silicone sealant the same as grout?  

No, grout is a cement-based filler used for joints between tiles, while silicone is a flexible, rubberised material used to seal corners and gaps where movement occurs. 

How long does it take for bathroom silicone to dry?  

Most silicones are touch-dry within an hour but require a full 24 hours to cure completely before they should be exposed to direct water or steam. 

How do I prevent mould from growing on my sealant?  

Choosing a high-quality sanitary silicone with built-in fungicides is the best defence, though regular cleaning and proper bathroom ventilation remain necessary. 

Can I apply new silicone over old sealant?  

New silicone will not bond correctly to old residue; for a waterproof and professional finish, you must completely remove the old sealant and clean the area first.
