How long after Danish Oil can worktop be sealed with silicone?

[Tim Brennan]

I am installing an Iroko worktop in my kitchen. This morning I applied a 3rd coat of Danish Oil (having applied a coat yesterday, and another the day before) - this is the brand I am using Colron Refined Danish Oil | Screwfix.com

The next thing I'd like to do is fit the undermount sink, which needs to be sealed with silicone.

How long do I leave the Danish Oil before attaching the sink and sealing it with silicone?

Welcome to the forum Tim.

I'm not familiar with that product but have used a range of DO's and all but one had driers in them so after even just a few hours they were dry to the touch.

Have also used a range of silicone sealants and in wet areas the damn things have all grown mould. Haven't used the ones claimed to be anti-mould that said.

When the plumber fitted my kitchen sink he used some other product; wish now I'd asked him what it was cos there's been little trace of mould at the edges.

Anyway, that ramble aside, my 2c worth would be to give the finish a few days to harden. Scratch with your fingernail on the surface. Then just provide a 'key' for a sealant by lightly sanding the edge to be covered.

HTH.

The kitchen sinks that I've installed at home all came with a seal attached to the sink. I just peeled of the protective covering and installed the sink, no further silicone required and no mould or leakage between the sink and bench top.

I have found those seals under the sink do not give a full waterproof seal.

With th danish oil it needs about 3 weeks before it is fully dry. If you use the sealent any earlier it may not stick properly and give a full waterproof seal.

Yep! you might get away with a bit earlier with high ambient temps, but.... if you get it wrong. It little longer maybe frustrating but as much as a seal failure.

Boys, he is in London and brought the Do from Screwfix, which is Pommy, so we can guess the ambient temps will be nothing like over here atm.

Tim, give it a month at least, given that you are in the middle of your winter and the average temps are in the low teens.
