Is there a real mould-proof grout available?
|
Am intending to rip out the old grout in a shower and redo. I have
heard that you can get grout that is mould proof. Someone suggested
the stuff they use in swimming pools!
Sounds unlikely to me!
|
I used a waterproofing additive in the grout -- BAL Add-mix GT1,
and that hasn't gone moldy in about 3 years since it was done.
|
Any advice please?

Mould is the product of poor ventilation. If you can improve the
ventilation you won't have a problem with mould.

Bleach. Regular application of diluted bleach.
Keeps grout and silicone sealant looking brand new.
Apply gently with a plant mister set on a coarse spray. Don't breathe
in. Leave until it looks white again. Rinse thoroughly with shower.

Yes you can get epoxy based grouts which are recommended for use with power
showers as immune to being washed away. Bit of a pain to work with as you
have limited time to grout once mixed (hint weigh out say 1/4-1/2 kg at a
time and corresponding amount of hardener) and also any left on tiles, bath,
fixings, hands, faces etc bonds like sh*te (other hint epoxy remover is
available as well and works well).
Found this one, but there are others.
I have regrouted my current shower tiles using a epoxy based white grout,
after the old grout stained (not so much mould but shampoo/soap, came away
with steam cleaner). With the epoxy the staining has not returned.
