Which sealant?

[Lemut]

Hi,
Could anyone advise me of a good sealant to run around an external roof mounted aerial base which is around 8" x 6". Currently there is a sponge sealing gasket under the aerial which would be a complete pain to remove/replace. As the leak is very small, I hope to use a bead of suitable sealant to stop it.
An appropriate Sika Sikaflex product would be my choice but I'm baffled by which one.
Can you help please?

If you speak to Sika they will advise the correct product to use.

Worth another punt Rob, if they will speak to me. I've tried in the past and my calls were never returned. That said, it was during Covid. Thank you your help.

Puraflex 40.

The Puraflex 40 PU in white looks like it would do nicely and I can buy a tube from a very local Tool Station. Double win? Thank you for your help.
