Used this to seal around a new shower enclosure. Left for the recommended 24hrs to cure. Leaked in serveral places, had to pull it all out & use other brand which was very easy as it didn’t seem to be fully cured. I won’t use again, as it was quite embarrassing having to go back & completely renew silicone after only couple of showers. If you want good sanitary silicone get Dow 785+, it worked perfectly as it should.

Fantastic silicone

I'm very impressed by this silicone. It applies really smoothly and gives a good finish when cured. Other reviews complained about the smell as it was curing but it didn't seem particularly strong to me and there's no odour once cured. I will be buying this brand again.

Absolutely brilliant product we used to seal our shower cubicle and whilst it took 12 to 18 hours to cure, the results have been excellent 👍

Used this to reseal a 15 year old shower. It was a real good thick product and solved the leaky problem. I would recommend this to you.

Goes on easy and leaves a lovely smooth finish. Always use bostik never had any mould growth issues with this sealant. Only gripe would be I wish they came with one of those screw on head tips which help to keep it fresh in between u

Perfect for it's applications.
