Black mould

[MICK the Tiler]

Mould also needs food, usually dust or something!?! Not sure how you would phrase that to a customer though... 😳:lol:

Food................Normally cellulose Wallboard plasterboard, but other organics will do dead skin cells.............YUUUK!!

I posted a thread similar a couple of months back, eventually tried the HG one (Leatherface mentions it above) it works really well as long as you leave it long enough to weave its magic!

just make sure its cleaned properly and then use an antibacterial Silicon

The trouble with antibacterial Silicon is that it only stops mould growth IN the Silicon. You can still get mould on top of the Silicon or the tiles around it that needs to be cleaned off. Proper ventilation is the real answer, though Microban type stuff does help.
