The main cause of water leaks in shower trays is due to a lack of care when applying silicone to seal it. We have created this guide to teach you how to properly shower resealing tray.


  • Quality silicone sealant – make sure it is suitable for use in bathrooms as it contains anti-mold technology and resists water and humidity, waterproofing the area. Select a type of silicone that is suitable for use on walls and floors.
  • Silicone Sealant Gun – to ensure even application of sealant.
  • Scraper for existing silicone
  • Paper towel – to clean up any excess silicone.


The best method to remove existing silicone is to use a silicone scraper, a utility knife, or a sharp knife. Use the remover or spatula to remove the old silicone, as they will make the process easier and faster at the time of doing it. In case of using a cutter, a knife must be careful not to scratch or damage the surfaces. If you are using the utility knife to remove spoiled silicone, select the correct opening as this will ensure a completely flat coating between the shower resealing tray and the tiles.

Don’t forget to wear protective gloves for any unforeseen events.


1. Make sure the area is completely clean and dry.

  • After removing the silicone, make sure you have cleaned and dried the walls and the shower tray before starting the process. This way you guarantee a better adherence.

2. Cut off the Tip of the Silicone Cartridge.

  • Once you have mounted the cartridge inside the glue gun, cut the tip at a 45 ° angle to ensure the hole is not too large.
  • The nozzle of the silicone cartridge is usually marked to help you cut the angle in the correct position. It is usually a 5mm hole, but you can enlarge it if necessary.

3. Apply the Silicone.

  • Optionally shower resealing, you can place a masking tape to help you when applying the silicone, although it is not necessary since there are spatulas to remove the excess. Remember that before starting the surfaces must be very dry and clean. We apply the silicone evenly as if you apply too much silicone it will be difficult to remove it once it has dried.

4. Verify There Are No Cracks or Holes in the Silicone

  • The silicone layer must be dense enough to completely occupy the space between the shower tray and the tiles.
  • Make sure in shower resealing, there are no visible gaps and in the event that any sections remain that have not been fully covered, apply more silicone to fully cover.

5. lean up any excess silicone.

  • Wipe off any excess silicone before it dries. You can use a specially designed spatula to do this.
  • Once you have applied the silicone to all the edges of the shower tray, remove the silicone cartridge so that no further silicone comes out of the cartridge (due to pressure).

6. Smooth the Silicone

  • Use a tool such as a scraper to smooth the silicone or use your fingers with a smooth cloth soaked in water before the silicone dries.

7. Let the Silicone Dry

  • Finally, allow at least 24 hours for the silicone to dry and you can use it correctly without any chance of leakage.
