Glass blocks - mould

[Mosaic]

I have a small bathroom - very dry with radiator and air extractor operated from lightswitch - it has a small section of glass blocks allowing outside light in. Is there anything other than regular scrubbing with bleach that will inhibit the mould growth on the cement between the blocks?

Reduce the humidity, mould requires a humidity above about 85% to grow.

Thanks Jomifl

if you can scrape some of the cement out and replace it ... but mix some bleach into the cement first, then re-apply

i do this with wall paper paste and some paints

use the thin stuff though, not the thick stuff as that can cause a slight yellowing.

A cunning ruse Joko - I'll give it a whirl
