How do I Get This Sink Out?

[paulrockliffe]

I've got a sink that I've taken out of an old kitchen. It's silicone sealed into the worktop and I need to get it out somehow. There isn't enough worktop to get any leverage on the worktop and the worktop is resin over chipboard so can't easily be ground out or cut out I don't think.

The sink is ceramic and overlaps the worktop surface, so I can't easily get at the sealant. I've already knocked one corner off the sink and don't want to wreck it completely.

Is there any clever tricks or chemicals I can use to get the sink out, to save me chucking it in a skip?

I'll give that ago, my only concern is that there's not much access to the silicone for the chemicals to get in.

There's no brackets underneath though, just silicone and gravity.

It's a ceramic inset sink.

I've tried Stanley knives, but there isn't enough of a gap to slide it in. I can't get the blade in to cut all the silicone, the overlap must be 15mm or more. There's also silicone holding it in on the inner edge of the cut-out, which needs a different approach.

Seems a shame to bin it, but I'm not going to spend hours on it.

Come on guys, we get the stanley blade or filling knife, but how does he get it out?

Answer:

Put a car jack under it with some wood on the jack face to spead the weight and apply upwards pressure; whilst cutting with an appropriate edge.

I like this, this could be made to work. Or punch holes through the sink, but it's worth a try.

The worktop is already broken and has warped since it was removed, so that's scrap already.
