Easy enough to use as silicone sealant goes!
I hate this stuff in general as it’s a pain to use but this wasn’t too bad, as a DIYer it was efficient and easy to apply. It’s all about having the right tools as I have a silicone smoother/shaper and I masked up the edges. Hoping it stays mould free, perhaps I’ll return to this review if it doesn’t.

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.

What a great buy!
This site was much cheaper than B&Q.
The silicone has a pre-cut nozzle and a cap to fit over once opened. No iffy smell (which is a bonus when you're stuck in a small confined space.)
Bright white in colour, it went on really easily with my sealant gun. (Gun for application needs to be purchased separately. Remember to click the release bit to stop the sealant continuing to ooze out of the end while you pause.)
Any mistakes can be easily wiped off and re-applied.
I'm so impressed with this, if it's also as anti-mould as it's supposed to be, it won't need re-doing for years! 😁

3.0 out of 5 stars Expensive but it’s ok.

This product is not clear as described, it is opaque. It was also very hard to squeeze it out of the tube. I used a metal cage, so it wasn’t a flimsy dispenser. This made application difficult and it’s an application you’d like to be done smoothly and consistently. I can see why some customers complained that the silicone burst out of the back of the tube.
