Whether you have used bathroom sealant around the bath, sink or tiles, it will eventually need to be renewed after a few years. As you can see in the above photo, the sealant can begin to discolour and become mouldy. It may also simply begin to wear away due to the fact that water is getting in behind it.

Removing bathroom sealant is a relatively easy task but only with the right tools. Simply using a screwdriver or pair of scissors is a recipe for disaster because you can end up scratching the tiles, bath or sink. To ensure that the removal of bathroom sealant goes to plan, we have created the below guide to give you a helping hand.

What You’ll Need To Remove & Renew

  • Sealant remover gel (optional)
  • Sealant remover/smoother tool (separate or combined tools)
  • Mould remover
  • Bathroom sealant (for renewing)
  • Cartridge gun

How To Remove Bathroom Sealant

  1. Apply the sealant remover gel to the old bathroom sealant and allow it to get to work.
  2. Use the removal tool with the pointed tip aimed at the old sealant.
  3. Gently run the tool along the sealant (little pressure required).
  4. Pull away any loose sealant from the surface.

It really is that simple to remove bathroom sealant and step 1 can be optional. The removal gel is used to break down the sealant for easier removal and you may even be able to pull the sealant off without the need for a scraper or knife. Some people even use WD40 to loosen up the old bathroom sealant if you can’t find any dedicated removal gels.

Regarding the removal tool, if you can’t get your hands on one, you can run a knife through the sealant instead and attempt to pull it off in strips. However, if you go down this route, take your time and remove small portions rather than one long strip.

If you notice that there are chunks of sealant left behind, use an old cloth and dab it in some white spirit. This helps to make the sealant less sticky and much easier to remove ready for the next step of renewing the sealant.

How To Renew The Sealant

When you are ready to renew it using a high quality bathroom sealant, you will want to prepare the area beforehand. For example, mould is very common when replacing sealant and you will want to spray a mould remover upon the surface and rinse it away after the manufacturer’s dwell time. You can then begin to renew the sealant as shown below:

  1. Ensure the surface is completely dry.
  2. Attach the sealant into the cartridge gun.
  3. Work from one end to the other without stopping.
  4. Apply consistent pressure and speed.
  5. Smooth down the sealant with a tool or your finger.


Removing bathroom sealant is relatively straightforward and although it can be achieved without any specialist tools or materials, it’s advised that you do. The saying “work smarter, not harder” is very much true when it comes to removing sealant. It’s also safer to use a dedicated tool that costs very little because it avoids any potentially costly damage too.
