i have an old and much loved wooden chopping board that is constructed with
strips of wood that are glued together. at one place the wood strips are
bending away from each other leaving a thin crack.
since its unhygienic, i want to fill it in with something. I have some PVA
waterproof adhesive which is quite thick and would probably fill the crack
up well, but would this be unadvisable using a chemical adhesive like PVA ?
thanks for any advice.
I know you asked about re-gluing, but I have to second the suggestion to rip
and reglue. Filling a crack does not feel good to me. If the wood is
moving, then the crack may reopen. Strongest method to hold things in place
is rip and re-glue.
I had a cutting board which developed cracks and like JWBH suggested, I
ripped and reglued. A few years later the board still looks good as new for
the glue joints. Lots of knife marks from repeated use.
The best idea is not to fill the crack, but to get rid of it entirely.
I had a built-in cutting board in the kitchen that was doing the same
thing. Last summer, I removed it, cut the separating sections apart
on the tablesaw, then planed everything to a uniform and flat
thickness and reglued it together. You can't see where the cracks
ever were, it's perfectly flat and square and good for another couple
decades of use.
