Silicone sealant plays an important role in keeping showers, bathrooms and kitchens sealed against moisture, but over time you may notice black mould or discolouration developing on the silicone. This is particularly common in warm, humid areas where water, soap residue and moisture regularly collect.
So, why does silicone turn mouldy, and can you stop it from coming back? In this guide, we look at the most common causes of mouldy silicone sealant, how to deal with existing mould and some simple ways to help keep your silicone joints cleaner and mould-free for longer.
Choosing the right silicone colour is an important finishing touch that can make a big difference to the overall look of your bathroom, kitchen or tiled area. The right choice helps create a seamless finish, while the wrong colour can stand out and disrupt the design.
In this article, we’re going to take you through the key points to think about when choosing the correct caulking colour. These tips, along with our reusable silicone extension nozzles, will help you get the perfect finish, whatever your project or room.
Selecting the right silicone colour is a small detail that can have a big impact, helping your finished project look polished, refined, and professionally completed.
A great caulking job isn’t just about sealing a gap. Neat, consistent silicone joints can make the entire bathroom, kitchen or wet area look professionally finished.
Whether you’re sealing around a bath, basin, vanity, benchtop or shower, good preparation and the right application technique can make all the difference.
Here are our tips for achieving a clean, professional silicone finish.
Applying silicone in tight spaces like behind basins, baths, vanities, downpipes, or under door sills can be frustrating with standard nozzles. That’s why we designed a range of extension nozzles to make sealant application easier and more precise.
Our extension nozzles can be screwed together to achieve the required length or angle, allowing you to reach even the most difficult areas. They are compatible with all silicone cartridges and standard poly gun nozzle adaptors.
The poly gun nozzle is reusable—simply let the sealant dry, twist off the adaptor, and replace the nozzle tip. Multiple extension nozzles can also be combined with 45–90° corner nozzles, giving you maximum reach and flexibility for complex applications.
Built with a rigid, durable design, our extension nozzles allow you to keep both hands on the caulking gun for better control and a professional finish every time.
Pro Tip: These nozzles are perfect for professional installers or DIY enthusiasts looking for a clean, precise seal in those hard-to-access areas.
