Replacing a mouldy shower seal with silicone: A guide for when your existing seal is beyond repair
How to Achieve a Professional, Watertight Finish with Silicone Sealant in Your Shower
For a durable, waterproof seal with a smooth and straight appearance around your shower, follow these steps:
1. Surface Preparation
Thoroughly clean the area to remove any dust, grease, soap scum, or old sealant residue. The surface must be completely dry before application. Use a suitable cleaner or rubbing alcohol if necessary to ensure no contamination that could impair adhesion.
2. Masking for Clean Edges
Apply masking tape along both sides of the joint where the sealant will be applied to create crisp, straight lines and prevent excess silicone spreading outside the joint.
3. Cutting the Nozzle
Cut the silicone tube nozzle at a 45-degree angle, making the opening size slightly smaller than the joint width for controlled, even application. The size of the bead can be adjusted based on the size of the gap.
4. Applying the Silicone
Apply the silicone sealant steadily along the joint in one continuous movement to avoid air bubbles and unevenness. Maintain consistent pressure on the cartridge gun to ensure an even bead.
5. Smoothing the Sealant
Immediately after application, smooth the silicone bead using a caulking tool, a wet finger, or a spoon dipped in soapy water. This shapes and presses the sealant into the joint for a tight, neat finish. Remove the masking tape before the silicone skins over (usually within a few minutes) to keep edges sharp.
6. Curing
Allow the silicone to cure undisturbed according to the manufacturer's instructions, typically 24 hours, before exposing it to water.
