A neat silicone seal makes all the difference to the look and performance of any job. From bathrooms and kitchens to windows and glazing projects, sealant plays a vital role in keeping out moisture, preventing mould, and ensuring a strong, watertight finish. The problem is that applying silicone by hand almost always leaves a messy bead. The key to achieving a professional result is preparation, the right technique, and - most importantly - using the correct finishing tools.
Silicone remains the most popular sealant because it is flexible, waterproof, and long-lasting. It is used everywhere, from sealing baths and sinks to window frames and tiles, and is trusted by both professionals and DIYers. However, even the best quality sealant will not perform properly if it isn’t applied and finished correctly. That’s why investing in dedicated sealant finishing tools is important.
Before applying fresh silicone, it’s essential to remove any old or worn sealant. This should be carefully cut away with a sharp blade and the surface cleaned to remove mould spores or residue that could stop the new bead from bonding. Once the area is dry, you’re ready to begin. Cut the nozzle of your tube at a clean angle and apply a continuous line of sealant along the joint. While the sealant is still fresh, use a finishing tool to smooth it firmly into the gap. This ensures the silicone bonds properly while leaving a clean, professional-looking finish.
At GGR Glass, we stock a wide range of specialist tools to make this process easy. A popular choice for all-round use is the Sealant Finisher Tool Set, which comes with four different shaped finishers so you can tackle a variety of joints and edges with precision. For jobs that involve adhesive mastics, the Mastic Sealant Finisher is the ideal option, with fine non-stick edges that create tidy joints on worktops, flooring, and similar applications.
Where angled joints are involved, the Angular Sealant Finisher is lightweight, flexible, and perfectly designed for creating smooth seals without sticking to the silicone. For awkward or out-of-reach areas, the Sealant Jointing Tool is a smart solution. It can be used by hand or attached to a pole, making it easy to achieve a consistent finish in difficult spots without damaging the glass or frame. If you’re looking for a ready-made solution, the Glazing Tool Kit with Bag offers a practical selection of essential tools stored in a durable bag, ideal for both professionals and DIY projects.
Using proper sealant finishing tools saves time, reduces mess, and transforms the quality of the final result. Instead of uneven lines or wasted silicone, you get a perfectly smooth bead that lasts longer and looks professional.
