Wood work top sealing conundrum

[blueST]

Ive bought a cheap Ikea birch kitchen work top. It appears to ready treated with oil, and a small test has proved that silicone won't stick to it. So, how do I go about sealing the joint to the wall and where it butts up to he sink?

Errr.. Any recommendation?

How about a liberal coating of even more oil, and then some wood beading similarly prepared and nailed to the wall at the junction..... Guess you'll say the wall is tiled

Wall isn't tiled, so that's an option. Don't think it would be any good where it butts the ceramic sink though.

sand where you need to seal and buy more oil to apply afterwards.

That might be the best option, but will depend how far the oil has soaked in. I'll do a test rub later.

Let the work top dry for a few days prior to sealing the joins to tile and work top. Using a good quality sanitary sealant such as Dow Corning 785 should work just fine.

It was Dow 785 that failed my test. Just peeled off dead easy.

Thanks all for the suggestions, but I can't see that any of the suggested sealants would adhere to an oily surface, unless I've missed something.

So, I'll see if I can sand back to fresh wood where I need to seal.
