How to Silicone over large gaps around a bath or shower - including tips and tools used.

Introduction

In this tutorial, you'll learn how to effectively seal large gaps around a bath or shower using silicone. This process can be challenging, but with the right tools, techniques, and tips, you can achieve a professional-looking result. Whether you're a DIY enthusiast or just looking to improve your bathroom, this guide will walk you through each step.

Step 1: Prepare the Area

• Remove Old Sealant:

  • Use a product like Multisolve to break down the old silicone. Spray it on the sealant and wait approximately 10 minutes until it softens.
  • Scrape off the old sealant with a scraper or a retractable knife.
  • Wipe away any residues with blue roll tissue.

• Clean the Surface:

  • After removing the old sealant, spray a light coat of Multisolve to eliminate any remaining marks or glue.
  • Use blue roll tissue to wipe the surfaces clean.

Step 2: Fill the Bath with Water

• Add Weight:
  • Fill the bath with water to mimic the weight of a person sitting in it. This will help prevent the silicone from pulling away once it cures.

Step 3: Apply New Silicone

• Choose the Right Silicone:

  • Use a sanitary silicone, such as Dow Silicone 785, which is resistant to bacteria and mold.

• Cut the Nozzle:

  • Cut the nozzle of the silicone tube to achieve an 8mm bead size. This size is ideal for most gaps.
  • Use a finishing tool to ensure a clean application.

• Seal Corners First:

  • Before filling the bath, apply silicone to any cracks or gaps in the corners. Stand in the bath to reach these areas easily.

Step 4: Install Trim

• Select Trim Type:

  • Choose a suitable trim to cover larger gaps. Options include quadrant trim or flat trim. For this tutorial, a 19mm quadrant trim is recommended.

• Cut and Fit Trim:

  • Measure and cut the trim to fit around the bath. Ensure it covers all gaps adequately.
  • Test the fit before securing it with silicone.

• Secure the Trim:

  • Apply a bead of silicone along the edge of the trim and press it into place.
  • Smooth the joints with a finishing tool for a neat finish.

Step 5: Finalize the Job

• Wait for Curing:

  • Allow the silicone to cure for at least 24 hours before removing the water from the bath. This ensures it sets properly and adheres well.

• Clean Up:

  • Remove any excess silicone and tidy the work area.

Conclusion

By following these steps, you can successfully silicone over large gaps around your bath or shower, ensuring a watertight seal that will last for years.
