How to Reseal Your Shower Tray and Prevent Water Damage

Resealing your shower tray is a crucial task to maintain its functionality and prevent water damage. By following our step-by-step guide, you can effectively reseal your shower tray and ensure its longevity.

Why Reseal Your Shower Tray?

Shower trays are prone to wear and tear over time, leading to cracks and gaps. These imperfections allow water to seep through, causing mold, mildew, and structural damage. Regular resealing is essential to:

• Prevent water leakage
• Maintain the tray’s integrity
• Enhance bathroom hygiene
• Extend the lifespan of your shower

Materials and Tools Required

Before you begin, gather the following materials and tools:

• Silicone sealant (anti-mold formula recommended)
• Sealant gun
• Caulk removal tool
• Utility knife
• Isopropyl alcohol
• Lint-free cloths
• Masking tape (optional)

Step-by-Step Guide to Resealing Your Shower Tray

1. Remove Existing Sealant

• Use a caulk removal tool or utility knife to carefully remove the old sealant from around the shower tray.
• Scrape away any loose or damaged sealant.

2. Clean the Surfaces

• Wipe down the shower tray and surrounding surfaces with isopropyl alcohol using lint-free cloths.
• This removes any dirt, grime, or soap residue that could affect the bond of the new sealant.

3. Apply Masking Tape (Optional)

• For a cleaner finish, apply masking tape along the edges where you will apply the sealant.
• This will prevent the sealant from spilling over onto the surrounding surfaces.

4. Apply Silicone Sealant

• Load the silicone sealant into the sealant gun.
• Hold the gun at a 45-degree angle and apply a continuous bead of sealant around the shower tray.
• Ensure the bead is thick enough to fill any gaps but not so thick that it overflows.

5. Smooth the Sealant

• Use a damp finger or a sealant smoothing tool to gently smooth the sealant bead.
• This ensures a uniform and watertight seal.

6. Remove Masking Tape

• If you used masking tape, carefully remove it while the sealant is still wet.
• This will prevent the tape from tearing the sealant.

7. Allow Time to Cure

• The sealant will take several hours or even days to fully cure.
• Refer to the manufacturer’s instructions for specific curing times.
• Avoid using the shower during this period.

Additional Tips for a Successful Reseal

• Use a high-quality silicone sealant specifically designed for showers.
• Ensure the surfaces are completely dry before applying the sealant.
• Allow the sealant to fully cure before using the shower to avoid compromising the seal.
• Inspect the seal regularly and reseal as needed to maintain its effectiveness.
• Consider using a sealant with a mildew-resistant formula to prevent future mold growth.

Troubleshooting Common Problems

• Sealant is peeling or cracking: This could indicate improper surface preparation, insufficient curing time, or using an incompatible sealant.
• Water is still leaking: Check if the seal is broken or if the shower tray has any cracks. Ensure the sealant was applied correctly and has had enough time to cure.
• Sealant is discolored: This can happen due to exposure to harsh chemicals or UV rays. Clean the seal regularly and apply a protective coating to prevent further discoloration.
