This sink is 100cm long. The extra length is on the drainer side.
The problem I have is that the laminate has lifted in an area close to the current sink. This video shows the extent: www.littletyke.myzen.co.uk/bubbled_worktop.avi
It's not that the laminate is loose. Just bubbled up. As the video shows, at worst the bubble is approx 5mm high.
The area of this defect, caused by water ingress swelling the chipboard core, is approx 9cm x 15cm.
However, the new sink should cover over this section, because the new sink is approx 10cm longer
But I'd really like to get rid of the bubble, and therefore propose the following:
When the time comes to do the replacement,
1. Remove existing sink.
2. Undermine the defective section by drilling edge-on into the core. Drill enough smallish holes to weaken the material.
3. The laminate should now be amenable to the application of weight or cramps.
4. So what I would do is fill the holes just drilled with wood hardener, then cramp the worktop to compress down the laminate and leave it for a day or two.
5. I would expect this will flatten out the bubble, at least enough so that the new sink will easily fit snugly against the worktop.
Does anyone foresee problems with this approach?
Or has anyone got any better ideas? I don't want to have to replace the entire worktop, which runs around the kitchen on three sides. The remaining worktop is fine. It's just this one area next to the sink.
