After learning a thing or two about working with beech block worktops i've decided to take apart my kitchen and refinish the worktops. This kitchen is around 4 years old and was installed before we bought this place. The worktops were finished in a shitty water based "oil" finish which doesn't seal the worktops properly nor was it applied with great care as the cut edges at the sink or the cooker top were never sealed and therefore were allowed to dry out and soak up moisture quicker than the rest of it. This has caused them to warp and crack quite a bit.
There are 2 worktops joined with a masons mitre: one contains the sink area and the other the cooking area. Im going to tackle the cooking one first to keep the sink in use for as long as possible.
First step was to quickly sand with 60 grit to remove the tile grout and silicone before i think about putting my nice planes near it. Scrubbing across the grain to level the whole thing out. This section wasn't actually too bad.
There was a section at the end that needed looked at, to me it looks like damage done during installation, probably tear out that wasn't glued down properly and this allowed water in.
I dimensioned a block of beech in such a way that it was a tight fit that wedged itself in harder the further in it was driven. This meant as soon as it was in I could cut it to fit and plane it. No need to wait for the glue to dry.
Now that the repair is complete I can get on with the next step.
