sealant for shower face plate

[aboleth]

The taps in my shower have an oval face plate around them. To prevent water getting behind it, there is a line of black high-density foam (about 8mm thick). I think the idea is that it should sit proud of the rim so that when the faceplate is screwed in place it gets compressed and makes a seal. Over time it has lost some of its thickness and started to let water in (which makes its way via a light fitting into the kitchen below).

Anyone know where I can get this sort of foam tape, or suggest an alternative? I don't really want to use silicone as I might need to remove the faceplate and redoing silicone is a right pain.

THanks,

use silicone, but place a sheet of polythene behind it.

Once set, remove polythene.

One fairly perfect seal.

Oherwise see if you can find some foam selaing strip as used for draughtproofing.

Thanks. I found a supplier of neoprene tape, but it was 30 quid a roll!
