Black Mould In Your Shower? Here Are Some Tips

March 7, 2017

Mouldy grout and silicone in the bathroom is a very common problem. Your lovely new shower won’t always stay new-looking! The tell-tale black marks can start to appear, making the shower area look unsightly.

What’s the best way to deal with black mould? Well, there’s treatment and prevention, and TBS can help you with both.

Prevent mould

Black mould forms because of condensation. This obviously increases in a hot, wet environment like a shower / bathroom. So check your ventilation. Opening a window a small amount when you use the shower or bath is a good move. But a more efficient answer is an extractor fan. TBS has a range of these, from a basic wall-mounted or window-mounted axial fans.

Treat mould

Search the internet and you’ll find various ‘folk remedies’ involving household chemicals (here is one example). Alternatively, you can buy a shower spray and use it on the tiled area after showering. Make sure you choose one which claims to kill fungal spores. Whatever you use, the important thing is to scrub the mould off after treatment, using very hot water and an old toothbrush. The point is that mould spores thrive in warm, damp conditions but are killed by real heat.

Here is a video clip on how to attempt a clean using only household bleach.

No treatment is foolproof, however, and the time may come when you will need to replace the silicone and the tile grout in your bath / shower area.  There are plenty of products on the market, but how about considering one which claims to guarantee against regrowth?



TBS stocks the FOREVER WHITE range of products from Everbuild.  These contain Microban, a leading fungicidal additive, so they don’t just repair, they protect.

Forever White Silicone (and its partner, Forever Clear) carries a Ten Year Guarantee against mould regrowth. It is permanently waterproof and flexible and ideal for sealing shower bases and cubicles, wet rooms, and around baths, sinks and basins. It is also ideal for use in kitchens and utility rooms and for sealing around window and door frames.
