UniBond 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.
