How To Remove Mould From Silicone Sealant

How To Remove Mould From Silicone Sealant

Whether it’s appearing around the shower tray or growing between the bathtub and tiles, there’s nothing quite as annoying - or as unattractive - as mould on your grout and silicone sealant. Not only does it make bathrooms look dirty, but it also causes silicone sealant to become brittle, rendering it ineffective over time.

Unfortunately, as mould loves warm, damp and humid environments, the bathroom is the one room in the home most likely to experience it, with showers, tiles and silicone sealant being especially vulnerable. Kitchens and utility rooms are also prone to mould issues, so be sure to take a closer look around sinks, drains and washer-dryers.

Causes Of Mould On Silicone Sealant

Mould is a type of fungi that can often be found growing on silicone sealant. While it might not seem like a big deal at first, black mould can actually cause a number of problems. The mould produces spores which can be released into the air and inhaled, leading to respiratory problems. In addition, the spores can also trigger allergies and asthma attacks.

So what causes mould to grow on silicone sealant? There are actually a few different factors that can contribute. One is simply age - over time, silicone sealant can deteriorate and become more susceptible to mould growth. Another factor is moisture - if there's excess moisture in the air, it can lead to mould growth on any surface, including silicone sealant. Finally, poor ventilation can also play a role, as it can create the ideal conditions for mould to thrive.

How To Identify If You Have Mould In The Bathroom

Mould thrives in warm, humid environments and is often found in bathrooms as a result. The spores are released into the air, and when they settle on surfaces they can quickly start to grow. 

As mould has the potential to cause allergic reactions and respiratory problems, it is important to remove it as soon as possible. But how can you tell if you have mould? Look for tell-tale dark patches on walls, ceilings or floors, particularly in corners or around shower heads. If you see mould, it is important to act quickly.

Unfortunately when mould has affected silicone sealants it is near impossible to remove the remnants. DIY cleaning methods may be successful, however staining will likely remain.

When To Remove and Replace Silicone Sealant

Sealants are an important part of any bathroom. They provide a waterproof barrier between your tiles and the rest of the room, and they also help to keep out mould and mildew. However, sealants can also be a breeding ground for mould and mildew if they are not properly maintained. As a result, it is important to know when to remove and replace silicone sealant.

Mould and mildew can start to grow on silicone sealant after just a few days, so it is important to check your sealant regularly for any signs of growth. If you see any black or green patches, this is a sure sign that mould or mildew is present. In addition, the sealant may start to feel slimy or tacky to the touch. If you notice any of these signs, it is time to remove and replace the silicone sealant.

To remove old silicone sealant, use a sharp knife or razor blade to score along the edge of the sealant. This will help to create a clean edge for the new sealant. Next, use a putty knife or similar tool to pry the old sealant away from the surface. Once the old sealant has been removed, clean the area thoroughly with soap and water. 

Finally, apply a new layer of silicone sealant and smooth it into place with your finger. Allow the new sealant to cure for 24 hours before using the shower or bathtub. By following these simple tips, you can ensure that your bathroom stays mould-free and looks brand new for years to come!

How To Prevent Mould From Returning

There are a number of steps that you can take to prevent mould from coming back in the future. Mould loves warm, damp conditions, so it's important to keep your home well-ventilated and dry. In rooms like the bathroom and laundry, use exhaust fans to promote air circulation. If you have an indoor pool, make sure to keep the area well-ventilated to prevent mould growth. 

You should also clean up any mouldy areas immediately and dispose of any materials that have been contaminated with mould spores.
