There's a very small long gap between the base of the kitchen mixer tap and the benchtop which allows water to leak into the cabinet below.
I am thinking to just silicone seal around the base of the tap on the benchtop, i.e. literally plugging the hole from where I can see it.
9" Caulking Gun - $2.30
Selleys 300g Wet Area Waterproof Silicone Sealant - Clear - $11.49
I am afraid if I loosen the screw down below and adjust the base to close the gap, I might make worse the already brittle/rotten wood because it looks like it's been happening for a long time. At least it's holding up with its current structure if I don't disturb it.
Need other opinions on a quick and easy fix.
