Bathroom Fitting Question

Whats the best white sealant for inside a shower?

I have recently added a little sealant to my shower where after being fitted there had been a little movement. I used CT1 thinking this would be perfect for the job as it says anti fungal on the reverse. 2 months in and i have a little mould. The shower was leaking a little and i put to this as it was always wet and new dried throughout the day.

The leak has been fixed and i want to remove the old mouldy seal and apply some new that wont mould.

Any help or advise and tips would be gratefuly recieved on removing, applying and the best product for such job.

thanks for your time.

I always use mapei sealants and have always been happy with them. You must always remove all the old sealant fully and make sure the gap is completely dry and free of dirt before you reseal. Use a hair dryer to dry inside the gap. You really should have a gap of 2-3mm any more or less then you could run into problems later on. Also to much movement could break the seal so make sure the tray solid on its base. Check for cracks or holes in the grout too as water can get in behind the sealant and cause mould as well.
