Choosing the Right Shower Silicone
A properly sealed shower is one of the most important parts of any bathroom. Good-quality silicone helps keep water where it belongs, protecting your walls, flooring and surrounding building materials from moisture damage.
Over time, however, shower sealant naturally deteriorates. It can crack, peel, become discoloured or develop mould, allowing water to penetrate behind tiles and fixtures.
Whether you're renovating your bathroom or replacing old sealant, choosing the right silicone and applying it correctly is essential for a long-lasting, watertight finish.
What Makes a Good Bathroom Sealant?
Not all sealants are suitable for wet areas. When choosing a product for your shower or bathroom, look for these important features.
Premium Sanitary Silicone
Sanitary silicone is specifically designed for bathrooms and wet areas. It remains flexible, allowing it to accommodate the natural movement of your home without cracking or separating from surrounding surfaces.
Mould Resistant
Bathrooms are exposed to constant moisture and humidity. Quality sanitary silicone contains mould-resistant properties that help keep joints cleaner for longer when combined with regular cleaning and good ventilation.
Long-Lasting Performance
Premium products provide better adhesion, flexibility and durability, helping maintain a reliable waterproof seal for years.
The Professional Bathroom Sealing Process
Professional caulking involves much more than applying a fresh bead of silicone.
Remove Existing Silicone
All old sealant is carefully removed to ensure the new silicone bonds directly to clean surfaces.
Clean and Prepare the Area
The joint is cleaned thoroughly to remove soap residue, dirt, moisture and any remaining silicone. Proper preparation is essential for good adhesion.
Allow the Surface to Dry
Silicone should only be applied to completely dry surfaces to achieve the best possible bond.
Apply Premium Silicone
Using professional caulking equipment, a consistent bead of sanitary silicone is applied along the joint.
Finish the Joint
The silicone is carefully tooled to create a smooth, neat finish that helps direct water away from the joint and provides a professional appearance.
Why Professional Bathroom Sealing Makes a Difference
While some homeowners choose to replace shower silicone themselves, achieving a neat and durable finish takes experience.
Professional bathroom sealing offers several advantages:
- Clean, straight silicone lines
- Premium mould-resistant products
- Proper preparation and removal of old sealant
- Long-lasting waterproof protection
- Improved appearance of your bathroom
Using the correct products and application techniques helps maximise the life of the seal while reducing the risk of future leaks.
