Bathroom Sealant

Question

Looking to remove the old silicone and reseal for a fresher look. What do you advise as the best bathroom sealant for around the shower tray, window and vanity/ sink unit. Looking into CT1, BT1 and Dowsil 785, struggling to separate them. 
Any comment or recommendations would be appreciated. Thanks

I personally use Downsil. CT1 is used more like a glue rather than a silicone that you put on your baths like Downsil or No Nonsense, etc.

Of the 3 you've mentioned I would purchase the dowsil, I use this more often than not

Rupert · Answer

CT 1 is very strong but it will go mouldy after five years. That’s why they brought out BT 1 to stop the mould. BT 1 is very strong and top quality. It’s difficult to get straight lines. How about masking tape?

I personally would use dow. CT1 is good stuff but but much for sealant. Tend to use that for sticking down toilets or anything i dont want to remove

Alyn · Answer

Screwfix do a good one for baths in there no nonsense rainge

Dean · Answer

We always use Dow Corning or mapei brands. I’m not sure the others your considering are flexible enough and you need a sanitary to avoid bacteria build up.

Doug · Answer

Use any make of sealant so long as it’s for sanitary use and has anti fungal in it
