Step by Step Toilet Gap Sealing Process

Surface Preparation
Thoroughly clean the gap between the toilet and wall with methylated spirits. Remove any existing sealant, dirt, or residue from both surfaces. Ensure the toilet base and wall are completely dry before proceeding.

Application Technique
Apply SS100 Wet Area evenly along the entire gap. Maintain consistent pressure on the caulking gun to create a continuous bead that completely fills the space between the toilet and wall.

Finishing Process
Use a smoothing tool dipped in soapy water to create a neat, concave finish. Remove painter’s tape immediately and clean any excess sealant before it cures.

For toilet installations where cleanliness and appearance are important, the SS100 Wet Area Matte Finish provides an exceptional solution. This specialised formulation creates a non reflective surface that resists dirt buildup and blends discreetly with bathroom fixtures. The matte finish maintains all the performance benefits of superior waterproofing and mould resistance while offering an easy to clean surface that enhances bathroom hygiene.

 

Technical Specifications and Safety

Consult the Technical Data Sheet and Safety Data Sheet for SS100 Wet Area  before beginning your project. The TDS provides performance data including mould resistance and flexibility specifications, while the SDS contains important safety information for bathroom applications.

 

Professional Application Tips

  • Ensure the bathroom is well ventilated during application

  • Work in temperatures between 5°C and 35°C for optimal results

  • Apply sealant in a continuous motion without breaks

  • Tool the sealant immediately after application for a professional finish

  • Avoid toilet use for 24 hours to allow proper curing

 

Maintenance and Hygiene

After sealing the gap, regular cleaning with mild bathroom cleaners will maintain the seal’s appearance and effectiveness. Avoid abrasive cleaners that could damage the silicone surface.
