How To Reseal A Leaking Shower Or Bath?


The most effective way to counter the effects of leaking shower, including water damage and high bills, is to repair the leak as soon as possible. If you are a DIY enthusiast, this is a possibility that will take you a short time as long as the leak is not extensive.

The silicone sealant is the best way to easily seal a leak in your shower. Poor application will not give you the best result. So here is a quick step by step rundown of what to do to achieve the best results.


What You Will Need

  • High-quality silicone sealant
  • Application tool
  • Sealant application gun
  • Paper towels or old clothes


Begin by reading the instructions from the manufacturer so that you use the sealant as indicated. Using a vacuum cleaner to remove any loose debris or dust in the area and clean the shower surface and let it dry completely. A couple of hours should do it.

Remove the old sealant by gently slicing it away using a sharp knife or chisel. Take care to avoid scratching or damaging the area where the sealant is supposed to go. To remove the remaining old sealant that may have refused to come off use some white spirit to dissolve it. Just place a little on a piece of cloth, rub it on until the sealant dissolves and sloughs off.

Step 1

Once the area is properly dried, apply the sealant to along the gap and ensure that the gap is completely covered. Using a stick, scrape off the excess sealant and use it to also push the sealant deeper into the gap.

Step 2

For a neat finish, use sugar soap to wipe off the excess sealant. Spray it onto a clean cloth and run it along the sealed joint wiping gently as you go. Make the wipe a single fluid motion and place consistent pressure as you go down.

Leave the fresh silicone sealant to dry for 24 hours or more depending on the magnitude of the sealing used.

Ensure that you use the right sealant for the building material in your bathroom so that the sealant works at optimum. For example, natural stone has a sealant that is compatible with it as does solid surface and tiles.

Safety Guidelines when Resealing your Shower Leaks

This is a project that must be undertaken with the best safety practices in mind. During the removal of the old sealant, ensure that you wear gloves to keep your hands safe. In addition, ensure that the knife or chisel you use is sharp in order to make your work easy and effective

When handling the white spirit, have a face mask to prevent too much inhalation during the process. Keep the gloves on during this period to prevent the solvent from touching your hands.

Apply the sealant using an application gun and when you are done, wipe any excess away from the nozzle before replacing the cap. Failure to do so will leave a messy nozzle with the sealant oozing out.
