Mira Silicone Sealant Tool
A simple, effective tool for creating a professional silicone seal finish.
Pros
- Comes with five different profile tips for various joint sizes
- Ergonomic handle with a soft-grip TPR coating is comfortable to use
- Very affordable compared to professional silicone finishing tools
Cons
- Fixed 90-degree angle makes it awkward for vertical or overhead applications
- Plastic construction feels a little light and may not last for heavy daily use
Who is the Mira Silicone Sealant Tool for?
This tool is primarily aimed at the home DIYer who wants to improve the finish of their silicone sealant work without spending a lot of money. It is ideal for sealing around a new bathroom basin, a kitchen sink, or a bathtub. The multiple profile tips allow you to match the tool to the size of the joint you are finishing, from a thin 3mm bead up to a thicker 10mm seal. It is less suited for professional tradespeople who need a more robust, versatile tool that can handle different angles and high-volume use.
Performance and Ease of Use
Owner reviews consistently state that the Mira tool works well when the surface is properly prepared and the silicone is applied evenly. The key is to use the tool to gently profile the silicone bead, not to force it into the joint. The five included profiles (flat, concave, and various radii) give good flexibility for common sealing jobs. The tool does not include a built-in guide or spacer, so you must rely on a steady hand to maintain a consistent distance from the surface. This can be tricky for beginners.
One common complaint is that the fixed 90-degree handle angle makes it difficult to use on vertical wall joints or inside corners without contorting your wrist. For horizontal work on a worktop or bath rim, it is much easier to control. The soft-grip handle is comfortable, but the tool's light weight means you have to apply your own pressure to get a clean profile.
Build Quality and Materials
The tool is made from a combination of polypropylene and TPR (thermoplastic rubber). The plastic feels adequate for occasional DIY use but is not as durable as stainless steel or aluminium alternatives found in professional kits. The profile tips are held in place by a simple friction fit, which some users report can loosen over time. The tool does not feel flimsy, but it is clear that cost savings were made on the materials. For the price, the build quality is acceptable for light to medium use.
Alternatives to the Mira Silicone Sealant Tool
If you need a more robust solution, consider a stainless steel profiling tool set from brands like Bahco or a multi-angle silicone tool from Stanley. These are more expensive but offer better durability and often include adjustable handles or guide wheels for more consistent results. For those who only have one or two small jobs, a simple silicone finishing spatula or even a damp finger can work, though the Mira tool provides a more repeatable profile.
FAQs
Does the Mira Silicone Sealant Tool work with all types of silicone?
Yes, it works with standard bathroom silicone, sanitary sealant, and acrylic sealant. It is not designed for use with epoxy or construction adhesives.
How many profile tips are included?
The kit comes with five different profile tips: flat, concave, and three radius sizes for different bead widths.
Can I use this tool for sealing around a window frame?
Yes, it can be used for internal window sealing, but the fixed 90-degree angle may make it awkward for vertical sections.
Is the tool easy to clean after use?
Yes, the plastic and TPR materials are non-stick to uncured silicone. Wipe the tool clean immediately after use with a dry cloth before the silicone cures.
Does the Mira tool include a guide or spacer?
No, it does not have a built-in guide. You need to maintain a steady hand to keep the tool at a consistent distance from the surface.

The soft-grip TPR handle is comfortable for short to medium tasks, but the tool is light, so you must apply your own pressure.

Yes, the concave profile tip is specifically designed for that purpose and works well on internal corners.
Is the Mira tool suitable for professional use?
It is best for DIY use. Professionals may prefer a more durable metal tool with an adjustable handle for versatility.
Does the tool come with a warranty?
Yes, Mira offers a standard 1-year warranty against manufacturing defects.
What is the main difference between the Mira tool and a silicone finishing spatula?
The Mira tool has multiple profile tips for different bead sizes, while a spatula usually only offers one flat profile.
Our verdict
The Mira Silicone Sealant Tool is a good value option for DIYers who want a better finish on their sealing jobs. It is not a professional tool, but for the price, the five profile tips and comfortable handle make it a worthwhile purchase for occasional use. For best results, practice on a scrap surface first.
