How to Seal a Bath


Replacing the sealant around your bath is the perfect way to freshen up your bathroom without having to spend excessive amount of money in doing so, as well as ensuring that mould is removed and reduced also. Daunting as sealing a bath yourself may sound, it is very possible and with help from these easy steps and guidelines, can be done with fast efficiency and little stress.

What Will I Need?

  • Sealant
  • Sealant Remover
  • Cartridge Gun
  • Plastic Scraper
  • Rounded Edge Tool

Getting Started

Removing Old Sealant

The first step in sealing your bath is removing the old worn sealant. You must first apply sealant remover to the seal and let it dry for 10-15 minutes. After this time period, you should take a plastic scraper and remove the sealant from around the bath. Following this, scrub the space with warm soapy water and dry.

TIP: Ensure you use the plastic scraper with care as you could scratch or damage your bath.

Preparation

Now, lay a strip of masking tape on both sides of each join you want to seal around the bath, making sure each piece is about 3mm back from the join so there is space to apply the silicone. Next you must fill your bathtub with water before you apply any fresh sealant. This prevents the new sealant cracking when you next take a bath. Now, attach the sealant cartridge into the sealant gun and cut off the end of the nozzle, making sure it is the same size as the gap you are filling.

TIP: Cut the tip at a 45-degree angle for easier application.

Applying New Sealant

Next, press the trigger on the cartridge gun and fill the gap with the fresh sealant, starting in the furthest corner so you don’t touch new silicone when you lean over the bath. Then, using the rounded edge tool, carefully smooth the sealant ensuring it is at an angle, which helps in shedding the water.

TIP: If you can’t find an appropriate edge tool to use, try the handle of a wooden spoon!

Leaving to Dry

Now, peel off the masking tape before the silicone dries and following the drying instructions on your sealant, leave to dry for the appropriate time period.

TIP: Any excess sealant on the bath can be easily removed with white spirit.

You Are Finished!

Your bath has now been sealed and is ready to use. A simple job can make such a difference to the overall fresh look of your bathroom.
