A smooth, professional finish on silicone sealant isn’t just about appearances — it’s the key to a watertight, durable joint. Whether you’re sealing windows, doors, bathrooms, or kitchens, using the right sealant finishing tool makes the job faster, easier, and much more effective.
At GGR Glass, we supply a full range of tools designed to give you that flawless finish every time. Here are some of the best options for your toolkit.
The Sealant Finisher Tool Set includes four compact tools with different shaped edges, each designed to tackle a variety of joints. Measuring 40x40mm, they’re small enough to carry in any kit, and their 2–6mm edges are perfect for finishing standard seals around windows, mirrors, and wash basins without applying extra pressure.
For adhesive mastics, the Mastic Sealant Finisher is a must-have. With two right-angled edges plus acute and obtuse options, it handles tricky joints with ease. Made from non-stick plastic, it’s lightweight, easy to clean, and delivers tidy results on jobs like countertops, laminate flooring, and more.
The Angular Sealant Finisher is designed for precision in angled joints. At just 40g, this lightweight, flexible tool is comfortable to use and ensures clean, sharp lines every time. Its non-stick finish prevents sealant from dragging, giving you a professional result with minimal effort.
For larger or awkward areas, the Sealant Jointing Tool is the professional choice. With a straight-edged design and a lightweight handle that can be mounted onto a pole, it’s perfect for sealing both horizontal and vertical joints in hard-to-reach places. Firm enough to shape sealant effectively but gentle enough not to damage glass, it’s an essential part of any glazier’s toolkit.
Before applying fresh sealant, it’s always best to remove old, worn, or mouldy silicone. A finishing tool can double as a scraper, especially when used with silicone remover, making the process far easier and leaving you with a clean, dry surface ready for resealing.
While it’s possible to smooth sealant with your finger, the results are rarely as clean or consistent. A proper finishing tool doesn’t just make the job easier — it gives you a stronger, longer-lasting seal. For professionals, these tools are essential. For DIY users, they’re an inexpensive upgrade that makes all the difference.
