How to remove and replace bathroom sealant with BT1

The sealant around your bathtub, shower, or tiles can get very discoloured and even mouldy over time. Mould sets in when the water has seeped behind the sealant. Once this happens, there’s really no going back. Even if you keep cleaning and removing the mould from the surface of the sealant, you’re still going to end up returning to the same job in a few weeks or months down the line. However, it’s relatively easy to remove and replace bathroom sealant as long as you have the right materials to help you out.

In this short guide, we’re going to walk you through the basic steps required to remove and replace bathroom sealant with the latest development in bathroom sealant technology, BT1.

 

What you’ll need to get started

Before you get started, you need to make sure you’ve got the right products and tools for the job. Here’s what we suggest:

  • Multisolve (sealant remover)
  • A Stanley knife or chisel
  • Mastic gun
  • Sanitary sealant (BT1)

 

Remove the old sealant

Before you ask, yes, you will need to remove the old sealant. It’s never a good idea to apply a new sealant over an old sealant, it’s just not going to work. Your best option is to remove the old sealant using a professional sealant remover such as Multisolve (you can buy this directly from our Online Shop if needed – the link to the shop is at the bottom of this article!). Multisolve is a multi-purpose solvent and is an excellent product to use for the safe removal of adhesives and sealants.

All you have to do is spray Multisolve onto the old sealant. Give it a few minutes to get to work. Within seconds, you’ll see the old sealant has lifted from the base surface. Once it’s ready for treatment, grab a Stanley knife or a chisel and get to work! Multisolve will make this process so much easier for you and the task becomes almost effortless.

 

Replace with BT1 Bathroom Sealant

Once all of the old sealant has been removed, you’re ready to apply the new bathroom sealant. We advise using BT1 because it is specifically designed for bathroom applications. It is made up of a unique formula that’s not only water resistant but is also mould-resistant. Microbes and bacteria cannot survive on the surface of BT1, which makes it a revolutionary sanitary sealant that delivers long-lasting results. On top of all this, BT1 is ETAG approved for bonding shower Panels without mechanical fixings.

You can use a regular mastic or skeleton gun for this step. Cut around 1cm from the end of the tube of the BT1 cartridge. You might need to cut more than that depending on the required diameter you’re after. Once that is done, you’re ready to re-seal where the old sealant was. Try your best to keep the application as neat as possible to avoid unnecessary clean up later.

So, whether you need to seal your shower panels, seal around a bathtub, or seal tiles in your bathroom, BT1 is the ultimate bathroom sealant for any bathroom application.
