"I used this to seal around a bath where there was a little movement, and ordinary acrylic sealant wouldn't dry due to humid conditions. It's not water-based, so won't dissolve if it gets splashed before curing.
This sealant is very viscous & quite hard to expel from the cartridge. It is also very sticky (as the name suggests).
Even when cured, it remains slightly tacky, but is very tough but also very flexible. It can be painted, unlike silicone. It claims to be very resistant to mould growth-I can't comment as I've only just started using it.
I was pleased to see it came with a resealable nozzle when so many manufacturers seem to have gone over to the disposable type."
