Review: Good quality sealant that helps prevent mould build-up - I used this around the bathroom sink and shower area, and it’s been a solid performer. It applies fairly smoothly and gives a clean white finish that looks tidy once set. The anti-mould protection is a big plus, especially in areas that are constantly exposed to moisture. It seems to hold up well and hasn’t shown any signs of discolouration so far. It does take a bit of care to apply neatly, as with most silicone sealants, and you’ll get the best results if you work quickly and smooth it properly before it starts to set. The cartridge fits standard guns and is easy enough to use for DIY jobs around the house. A dependable sealant that does its job well and helps keep kitchen and bathroom areas looking clean and protected. Review: Easy to Apply and Excellent Waterproof Finish - 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. ## Features - May cause an allergic skin reaction. - Toxic to aquatic life with long lasting effects. - Anti mould sealant - Once dry, the UniBond sealant forms a permanently flexible, mould resistant & waterproof sealant, ensuring strong seals and preventing mould growth. - Specially formulated - The formula of this shower sealant is ideal for warm and humid environments such as bathrooms, kitchens and other tiled areas or surfaces. - High adhesion - Create a perfect and long-lasting seal with this durable, high-strength kitchen sealant.

It is the reference being use to indicate that the container it comes in can be resealed by the screw top cap **Q: Would this work with a sealant gun that takes 310ml or 400ml cartridges?** A: I am not going to be very helpful but the cartridge is 274g. it would fit into a standard cartridge gun OK. **Q: Could this be used around pvc windows?** A: Yes it can be. Sealed my bath and looks great. **Q: Is this suitable for sealing plastic and metal together** A: Yes it will be able to fill the gaps between plastic and metal surfaces and will prevent any leakages, but it shouldn't be used as a substitute for glue to hold them together. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality sealant that helps prevent mould build-up *by A***S on 8 June 2026* I used this around the bathroom sink and shower area, and it’s been a solid performer.

A dependable sealant that does its job well and helps keep kitchen and bathroom areas looking clean and protected. ### ⭐⭐⭐⭐⭐ Easy to Apply and Excellent Waterproof Finish *by P***L on 2 February 2026* 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.

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. ## Frequently Bought Together - UniBond Anti-Mould White, Waterproof Mould Protection, Long-lasting White Silicone Sealant for Kitchen & Bathroom, Powerful Bath Sealant, 1 x 274g Cartridge - Unibond Sealant Finishing Tool, Effective Sealant Tool for a Smooth & Professional Finish, Sealant Smoother for All Sealants, Silicone Sealant Tool for Wall & Floor Applications - ProDec Extra Strong Caulking Gun --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/47868225-unibond-anti-mould-white-waterproof-mould-protection-long-lasting-white](https://www.desertcart.pt/products/47868225-unibond-anti-mould-white-waterproof-mould-protection-long-lasting-white) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-24*
