If you’re dealing with a leaking shower or planning a bathroom renovation, choosing the right silicone sealant is key. A high-quality sealant keeps your shower watertight, prevents mould, and extends the life of your bathroom. But with so many options on the market, how do you pick the best silicone sealant for showers in Australia? Here are five essential features to look for.
1. Waterproof and Leak-Proof Protection
The main purpose of a silicone sealant is to create a watertight seal. A good quality sealant should be 100% waterproof and prevent leaks for years. If your shower has gaps or weak seals, water can seep through and cause damage to walls, floors, and even structural elements of your home. To avoid costly shower repairs, invest in a sealant that is designed for high-moisture environments.
2. Mould and Mildew Resistance
Bathrooms are naturally humid places, making them a perfect breeding ground for mould and mildew. Over time, a poor-quality sealant can develop black spots or a slimy film due to constant moisture exposure. To keep your shower looking clean and hygienic, choose a silicone sealant with strong mould and mildew resistance. Some brands include antibacterial properties to further prevent fungal growth.
3. Long-Lasting Durability
A shower is used daily, meaning the sealant must be strong enough to handle constant exposure to water, steam, and cleaning chemicals. High-quality silicone sealants remain flexible and intact for years without cracking, shrinking, or peeling. If you frequently need to redo your shower seals, it may be time to switch to a more durable option to reduce ongoing leaking shower repairs.
4. Strong Adhesion to Bathroom Surfaces
Your shower silicone should adhere well to common bathroom materials such as tiles, glass, ceramic, and acrylic. A poor adhesive can result in gaps or peeling over time, allowing water to penetrate and cause damage. Look for a sealant that bonds securely to different surfaces and forms a strong, flexible seal that moves with your shower’s natural expansion and contraction.
5. Easy to Apply and Quick Drying
Whether you’re sealing your shower yourself or hiring a professional, an easy-to-apply silicone makes the job much smoother. A good sealant should have a smooth consistency, allowing it to be applied without mess or difficulty. Quick-drying formulas are also a plus, as they minimise the waiting time before using your shower again.
Final Thoughts
Finding the best silicone sealant for showers in Australia doesn’t have to be complicated. By choosing a waterproof, mould-resistant, durable, and easy-to-apply sealant with strong adhesion, you can prevent leaks and keep your shower in top shape for years. If you’re struggling with ongoing shower repairs due to leaks or worn-out seals, investing in a high-quality silicone sealant can save you time, money, and stress in the long run.
