How best to remove mould in shower room?

adamt11 · 1 Feb 2018

I have a mould problem in my shower room. I can wipe it off where it appears but it always comes back. There's mould along the bottom of tiles in the lining.

What would be the best way of 1) removing the lining that has the mould infiltration and 2) replacing it? I have some inexpensive bathroom silicone in a tube and wonder if this would be good to use and if so what would be the best way of applying it evenly along the edges.

Thanks

Looks a mess , remove all and replace, you can only prevent mold buy providing adequate ventilation.

Drying after every shower will certainly minimize it. It sounds like a hassle but its really not, once its in the mindset.
But it needs completely replacing first, once its moldy its moldy.

Yeah it's bad, the mould gets everywhere. I don't know what else I can do about ventilation. I keep the window open and there's an extractor fan. It's a council property and I've told them numerous times but they don't listen. Never had this problem anywhere else I've lived.

It grows on the walls and even on the shower curtain. I do wipe the floor after showering but it has not improved things.

You need to wipe the floor, wall and tiles. The shower curtain will need to be washed/replaced periodically.

Does the extractor actually extract, and where does it go to - if you do some investigating you can present the council with an exact problem, ie. fan not functioning . It should be enough on it's own without the window.

Is the house double glazed? How effective are the seals?
Whilst an extractor fan will remove humid air that air does need replacing… If there is no way fresh air can get into the room/house then the extractor fan will have little impact. When the fan is on it is worthwhile opening a window (possibly in another room).

Total house ventilation is good but can affect keeping the house warm. Heat exchangers help encourage use of the fan - e.g. https://www.amazon.co.uk/KAIR-RECOVERY-SILENT-EXTRACTOR-ANTI-CONDENSATION/dp/B004VW3RGW
but the council may not want to know or help.

We get a little mould. Bleach the walls when cleaning. We have a fan heater high on the wall by the door - this really helps to get the steam out fast, and reduces the amount the can condense (warmer air can hold more moisture). The difference is amazing really, probably more effective than a more powerful extractor fan. Although, a more powerful fan is also good. Does your fan stay on for a while after you leave the room? One with a timer is a good idea - we don't have that yet. I just leave it on and try not to forget to turn it off!

All the above plus: never use cheap silicone, the manufacturers save cost by reducing the amount of fungicide in the formulation.

Bleach, sold as mould remover, will almost make the mildew disappear.

Many small shower room fans are woefully inadequate needs to be powerful, you also need to avoid leaving bottles and contains on the floor of the shower as they impede air movement.

Temporary fix. Roll up some toilet paper like a very thin sausage. Lay it across the silicone, shower tray etc. Pour some bleach on to toilet paper and make sure it is nicely rolled up and squashed into corners.
Leave a few hours and mold free..

Although it will come back if silicone seal is broke and water/moisture getting behind silicone
