If you live in an older house with solid walls, you may well have a problem with damp appearing on your interior walls. This is almost certainly caused by condensation. There are things you can do about this, and TBS can help you.

First, check that your home is properly ventilated. One very practical answer is to fit extractor fans. TBS stocks axial fans and centrifugal fans from Manrose, some with a built-in humidistat, together with a range of grilles and ducting that should meet your requirements, .

Another thing to consider is dry lining the walls. It’s a bigger job but can make a serious difference. Click here for an overview of what’s involved – very handy if you’re considering the DIY option.

Batten frame with insulation being added

Dry lining involves fitting battens to the walls, adding insulation, then fixing a plasterboard wall. The frame can be made using 25 x 38mm battens. Insulation could be either 25mm polystyrene or Knauf Dritherm cavity wall insulating batts.

Now you have two options. Either tack a polythene vapour barrier to the battens, then fix 9.5mm plasterboard. Or you can opt for Knauf Vapourshield plasterboard, which is already backed with silver foil.

TBS stocks all the products you would require for dry lining. So call our Sales team at any TBS depot for information, advice and some good prices.


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.
