A Guide to the Best Methods for Sealing a Shower Tray

We go over how to properly seal a shower tray in this easy, step-by-step tutorial so you can get the perfect shine.

You’ll also learn how to remove the old sealant and prepare the area for the new silicone sealant. A quick and easy option to update the look of your bathroom is to replace the sealant surrounding your shower tray.

How to remove an old silicone sealant in the shower tray

The easiest way to remove old silicone sealant is to use a sharp knife, chisel, or Stanley knife while wearing heavy safety gloves to gently slice away as much sealant as possible. Be careful when doing this to avoid scratching or harming the surface.

After removing most of the sealant from the surface, you should be left with a few thin strands. rub it off with your finger or thumb, or use white spirit – simply put some on an old cloth and massage over the remaining strands until they come off or dissolve.

The most critical aspect of applying silicone sealant is preparation; follow these top guidelines to achieve the best possible outcomes.

  • Always read the directions provided by the manufacturer before using silicone sealant to ensure proper application and avoid leaks. Before the sealant is exposed to water, it needs to be cured completely.
  • Vacuum away any dust and tiny deposits, and then wipe the shower tray surface and tiles with a damp cloth soaked in warm water and mild soap before applying the new sealant.
  • After cleaning, use a moist cloth to get rid of any detergent and a paper towel to dry the area.
  • If there is any moisture remaining, the silicone sealant may not fully bond to the surface, so let the shower tray dry for a few hours before applying the sealant.

How to properly seal a shower tray

Below are some tools and things you need:

  • Sealant application gun
  • Paper towels
  • Use a premium silicone sealant
  • Use the correct sealant

Step 1. Make sure the area is completely dry

Make sure the shower tray and walls are fully dry and free of dust and dirt before applying the new sealant.

Step 2. Choose the right aperture size

If you use a tool to smooth the sealant, use the right aperture size so that the completed bead entirely covers the gap between the tiles and tray for a waterproof finish.

Step 3. Remove the application nozzle

Remove the application nozzle on the sealant tube at a 45-degree angle, ensuring that the hole is not too large. The nozzle will include marks that show where and how to trim it. A 5mm hole is standard for most applications, however it can be extended if a larger bead is required.

Step 4. Spread an even bead of silicone sealant

Start at the shower tray’s inner corner, apply gentle pressure to the application gun’s trigger, and work your way to the front of the tray in one continuous movement. Make sure you apply an even bead of silicone. Don’t apply too much because it will be hard to remove.

Step 5. Ensure there are no obvious gaps

The silicone sealant bead should be thick enough to completely cover the gap between the tray and the tiles. Ensure that there are no obvious gaps; if there are, gently apply extra sealant to the area.

Step 6. Wipe away the excess

When you’ve finished each line of sealant, reduce the pressure from the application gun, or the sealant will continue to pour from the nozzle. Wipe away the excess and replace the cap.

Step 7. Smoothing out the sealant

Put the smoothing tool against the tray and tiles, starting at the area where you originally applied the sealant, and apply mild yet constant pressure, moving the tool along the length of the tray to remove excess sealant and leave an even bead.

Once you’ve made a smooth bead, stop smoothing the sealant since it may tear, become messy, and may not stick properly.

Step 9. Allow to completely dry

Let the newly applied silicone sealant dry for at least 24 hours to ensure a waterproof barrier against potential leaks.

Following the methods given, from removing old sealant and properly cleaning the area to choosing the right silicone sealant and applying it precisely, offers a professional finish that improves the appearance and durability of your shower. Proper drying time is essential for the sealant to cure properly and form a water-tight seal. With these methods, updating your shower tray may be a simple DIY project that adds a professional appearance and long-lasting performance to your bathroom minimising the risk of water damage when you use the shower.
