Anti-Mould White, Waterproof Mould Protection, Long-lasting White Silicone Sealant for Kitchen & Bathroom, Powerful Bath Sealant, 1 x 274g Cartridge

After using this UniBond Anti-Mould White Silicone Sealant, I’m genuinely impressed by the finish and the 5-star protection it provides in high-moisture areas like the shower. The application is smooth and the "waterproof" claim holds up perfectly, preventing that dreaded yellowing or mould buildup. However, for a real-life result, keep in mind that the "anti-mould" feature only works if you meticulously remove every trace of old sealant and dry the area completely first. It has a fairly strong vinegar-like scent during application that lingers for a few hours, so make sure you have a window open. It's a reliable, professional-grade choice as long as you don't rush the curing time.

I used UniBond Anti-Mould White Silicone Sealant to reseal several areas in our bathroom, including around the sink, the base of the toilet, and the edges of the shower. The sealant came out smoothly and was very easy to work with, even for someone like me who isn’t a professional. It spread evenly without clumping and was simple to neaten up with a finishing tool. By the next day it had dried completely and now feels fully waterproof with a clean, bright white finish. The anti-mould protection is a big plus too, as these areas are always prone to damp and staining. Overall, I’m really pleased with the result – it looks neat, seals perfectly, and has refreshed the whole bathroom. I’d happily buy this again and would recommend it to anyone needing a reliable, good-quality sealant.

I used this UniBond White Silicone Sealant to re-finish a kitchen worktop. After two years, the majority of the sealant is still bright white, however, there is a small patch of black mould on the section just behind the taps. To apply the sealant, I found the best method was to use a plastic sealant finishing tool (See below). This tool helped me to smooth out the sealant and create a clean, professional-looking finish. It also made it easy to control the amount of sealant that was applied, which helped to prevent any excess from building up. The sealant itself was easy to use and had a nice consistency, making it easy to spread and smooth out. It had a typical sealant smell and didn't cause any irritation when I used it. In general, I found this sealant to be a good quality product that was easy to use and provided a nice finish. However, the small patch of black mould on the section just behind the taps is a reminder that it is important to keep the surface clean & dry. Applying this can be done with a standard caulking gun, but for a more professional finish, a plastic sealant finishing tool can be used. Here are the steps to apply the sealant with a plastic sealant finishing tool: (YouTube also has some good videos showing how to apply it using the tool) 1. Cut the nozzle of the sealant tube to the desired width. 2. Apply a steady and consistent bead of sealant along the area where you want to seal. 3. Use the plastic sealant finishing tool to smooth out the sealant, ensuring that it is evenly distributed and fills all gaps. 4. Use the tool to create a smooth and clean surface, paying special attention to corners. 5. To apply the sealant around corners, hold the tool at a 45-degree angle and use the corner of the tool to press the sealant into the corner. Then use the flat edge of the tool to smooth out the sealant, making sure that the corner is filled and the sealant is flush with the surface. 6. Clean any excess sealant with a damp cloth or paper towel. 7. Allow the sealant to dry and cure according to the manufacturer's instructions. It is also important to note that the surface should be clean, dry and free of any mould before applying the sealant. If there is any mould, it is important to remove it before applying the sealant in order to ensure the sealant will adhere properly and prevent the mold from coming back.

This silicone sealant works really well for kitchens and bathrooms. Its easy to apply, sticks firmly and provides a strong, waterproof seal. The anti mould formula is effective and it keeps areas clean and protected for a long time. The white finish looks neat and professional making it suitable for visible areas around sinks, baths and tiles. A high quality, dependable sealant that does exactly what it promises.
