Best Sealants / Caulk For Glass Shower Stalls. Anti-Mould? Hard Glossy Type?

Recommended Posts

This is because silicones have slight porosity that allows water, micro-organisms and spores etc to attach itself to the surface of the sealant

Silicone is already water resistant so how can mould attach to it?

The thing with silicone is that the water resistance breaks down after few years, causing mold to seep in

Correct its just due to normal wear and tear for the silicone

Silicones have slight porosity, ie tiny holes which allow the spores to attach itself to the silicon. If it is not cleaned, it will turn mouldly after some time. The silicon itself is still water resistant, but the bonding to the surface that it is attached to may be worn out.

Anti mould silicone can help as these contains some fungicide to kill the mould but not sure how long it can last. My personal experience is 1-2 years, but there are people who claimed to last 5-10 years. My guess is depending on how humid the surface is (?)

Cheers

Thats so true and those spaces when added with moisture and our humid weather its just the best environment for molds

Currently it is sealed with silicon

But before you seal it make sure the mould spores are killed first else the mould will start to infect the silicon too
