Great silicone for sealing around shower trays and baths. Smooths out well. It is considerably more expensive than the standard silicones but it does seem to have good anti fungal properties.

Although this silicone is relatively expensive compare to most brands available, it is well worth the money as a easily applied highly flexible sealant

Solid product, applies well, highly flexible. Everything you would want in a silicone just much more expensive than most other brands on the market.

Used for the first time a few weeks ago,
Really impressed, usually use worth silicones but needed some on short notice.
Payed over the odds for it. But it went on well. Cleaned up and seems to have adhered really well.
