I plan to fit a new stainless steel kitchen sink in the new year. The
current sink is an Astracast-type sink (composite) which is 90cm long.
The new ss sink will probably be a Franke Ascona ASX 651 1.5 Kitchen
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:
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
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
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.
