That's a long title. Basically I have made an outdoor grill/kitchen area, and the timber worktops have holes for stainless steel tureens to drop into. See pic.

I'd like to use something to slow the water ingress, and am visualising a self stick rubber gasket, not unlike draft proofing, for the tureen to sit on unobtrusively, and to be a 'wall' (1/8th" high) around the lip of the hole. I don't want to silicon them, 'cos I bring food back and forth from the indoor kitchen, so need 'em removable.

Any ideas? Ta.

Is this to waterproof the empty hole?
Or waterproof the tureen in use?
Or the tureen when left empty?

1. No, the tureen and lid stay in situ when not in use (but they let water down the sides).
2. No
3. Yes, so when it rains, and water falls on the surface and tries to flow under the flange of the tureen and into the hole, the 'gasket' will stop it.

Ta for the reply
 
You could do a couple of experiments and use silicone sealant but with something like vegetable oil / washing up liquid as a release agent?
Rig something that stops the tureen resting on the timber by about 5mm, oil the tureen and add silicone and dress it smooth. Then allow contact with the tureen- in theory the silicone would mould to leave a profile that does what you want?

Another thought is boat building suppliers and gaskets for skylights?

A place near me has sold rubber for over 100 years and is full of profiles etc. Something like a P profile is what you may need?

Another option would be a sheet of 5-9 mm thick rubber/neoprene bigger than the top of the tureen.
Cut an access hole for the tureen to go through, then cut the outer to match the curve of the outer border.

A strip of the same or thinner could be used on the cut worktop and glued to the top gasket.if you started with the rubber on the edge, and folded it over the top, it would slightly force the rubber up at the edge.
You could even use a (new) bicycle inner tube for that

Use a bloody sharp knife to cut the rubber.

Rains not going to do any more harm thru the holes than across the top .

It can do if the inside surface is end grain and much harder to seal than edge grain.

You could try making a large 'O' ring from o ring cord. Form a circle to the diameter you need and join the two ends with superglue. Both ends of the cord need to be perfectly flat when you cut them to provide a good mating surface.

How about caravan window seals? They work similar to car door seals but they are available to fit board from about 18-35mm and they have a seal surface that works in the same way a car door is sealed. It can be made to go around fairly tight bends but it does need an insert strip too to expand it. You could silicon the edge of the board before you fit it if you want to
