UniBond Anti-Mould White

UniBond Anti-Mould White Silicone Sealant Review (First-Person Experience)

When I first started noticing dark mould forming around my bathtub and kitchen sink, I knew it was time to replace the old, cracked sealant. After trying a few cheap options that peeled off or discoloured within months, I finally decided to give UniBond Anti-Mould White Silicone Sealant a try. Honestly, I wasn’t expecting much difference—but this sealant completely changed my mind about how easy it can be to maintain a clean, mould-free bathroom and kitchen.

The first thing I appreciated was the smooth application. I used a standard cartridge gun, and the sealant came out evenly without any annoying clumps or gaps. The consistency is perfect—not too runny and not too thick. It’s easy to guide along the edges of a bathtub, shower, or sink, and I could quickly shape it using a finishing tool or even a gloved finger. What really stood out to me was how neat and professional the final finish looked. The white color has a glossy, clean tone that instantly refreshed the look of my bathroom.

After applying it, I let it set overnight, and by the next day, it was completely waterproof and firm. The seal around my bathtub looked flawless. I tested it with running water, and there were no leaks or soft spots. The best part is that even after several months, no signs of mould or discoloration have appeared. UniBond’s anti-mould formula really lives up to its claim—it provides a lasting barrier against damp and mildew, which is a big relief for anyone tired of constant cleaning.

Another thing I liked is its durability. I’ve cleaned the sealed areas multiple times using standard bathroom sprays and mild bleach solutions, yet the sealant remains as white as ever. It doesn’t peel, crack, or turn yellow, which is something I’ve often seen with lower-quality sealants. The flexibility also makes it ideal for areas that expand slightly due to temperature changes—like around sinks or tiled walls—so it doesn’t lose adhesion.

Using UniBond also gave me peace of mind knowing it’s specifically designed for humid environments. It’s perfect for both kitchens and bathrooms, which are typically high-moisture areas where mould loves to grow. It’s also great that UniBond is a trusted brand, known for producing reliable home repair and sealing products. I felt confident using it, especially because it’s made for long-term use and designed to resist daily wear and tear.

Applying the sealant didn’t take much effort, and the instructions were very straightforward. The cartridge is compatible with standard guns, so I didn’t have to buy any special tools. I simply cut the tip at an angle, loaded it into the gun, and began sealing along the edges. The quick drying time is another plus—it started to set within 20 minutes and fully cured within a day, leaving a strong, elastic seal that looks fresh and clean.

Overall, I can confidently say that the UniBond Anti-Mould White Silicone Sealant is one of the best sealants I’ve used for both bathroom and kitchen projects. It’s waterproof, long-lasting, and mould-resistant, exactly what I needed to keep my home clean and protected. If you’re looking for a professional finish that stays white and fresh for years, this sealant is absolutely worth it.

Whether you’re resealing a bathtub, sink, or tile corner, UniBond’s anti-mould formula saves you from frequent replacements and messy black mould spots. It’s easy to use, gives a clean result, and keeps your surfaces hygienic—making it a smart investment for anyone who values both appearance and durability in their home maintenance projects.
