UniBond Triple Protection Stop Mould Silicone Sealant For Kitchens and Bathrooms, Clear, Repels, Kills and Prevents Mould Growth, Long-Lasting Shower Sealant, 1 x 291 g Cartridge

I have used this to replace a bath seal that had started to develop black mould spots. How long it will last only time will tell. But if the reports I've read are accurate, this sealant is probably the best on the market.

on the expensive side but seems like a good product, time will tell, doe not smell of vinegar like most silicone sealants do, goes on well will minimal tooling, I used masking tape and got a very neat seal on my glass shower enclosure

Good and better sealant

Works well in our hard water .area. Brilliant white fits into the Amazon recommended gun

I won't buy any other sealants for use in bathrooms. Great adhesion. Great mould resistance. Easy to apply. Great stuff!
