Silicone sealer goes mouldy quickly

[Cliffpope]

You know the standard white sealer used round showers, sinks etc?

Why does it discolour and go mouldy so quickly? It's supposed to be waterproof, yet it seems to become impregnated with mould that won't clean off.

I did a nice job round our Belfast sink set in a worktop, but now 3 months later it's blackened and looking tatty.

Is there anything better to use?

Everbuild Forever White.

I've also used BT1. Very good.

Because it is in a warm, high humidity/damp environment.

The problem is where it is, not the sealant.

That's what I'm saying - sealants are not designed for warm high humidity damp environments.

So what is? Is anything?

Mould.

Forever White in our bathroom for 5 years now is still like new.

 

Tbh it's so ****ING cold in there I don't think mould can grow 😂

As I recall there are two families of sealer, think it's acid and non acid? Someone will remember which is better.

Don’t let water sit on the sealant regardless of how good it claims to be. We wipe down and dry the shower every time we use it. Done it for years and never had any mould problems.
