What adhesive to use around replaced piece of floorboard?

[Littlelumley]

We had a section of floorboard removed to check for pipes etc prior to attempting to rid some squeaks… the cuts were luckily on joists at each each, but now obviously we have gaps where the saw went around… what is the best glue/filler for this please?

Providing you have properly supported and screwed the board back down adequately it generally isn't necessary, and in any case it won't achieve much because you presumably have some 3mm gaps around the replaced part - and wood adhesives are not fillers. If you wanted to use glue you should have used it to glue down the replaced piece(s) onto the joists or bearers, where it will make a difference

If you do want to seal the gaps I'd suggest some foam underlay, Fossa Caulk Saver, etc pushed into the gaps might be a more sensible approach than a permanent filler - you never know, you may need to lift that floor again in the future...

The flooring didn’t even get lifted as it was found to be stuck to the joists anyway. But we were able to see where the joists were (thankfully where it was cut was actually half way over the joists). I just wanted to make it look a little prettier haha

Floor repairs never look pretty IMHO (or maybe it's what plumbers and sparkies do to my lovely floors which isn't pretty ), unless that is an OCD joiner has taken the time to do the cut out really neatly (plunging saw and saw guide) and replace the same way. If it really needs to be good replacement I cut out, but replace with a new piece of flooring trimmed to be a near perfect fit in the 'ole. That does benefit from glue on the edges, but it takes a bit of skill and patience (based on how few site guys I've worked with who can do it right). Anything else is really bit of a bodge

I would point out that if an in any way competent diy’er or pro did this, it wasn’t “lucky” that the cuts were on a joist. It should have been PLANNED that way

Against that, there is the problem that where you want to run the saw cut is often exactly where the row of screws (or nails) happen to be - and of course the so and so's never want to unscrew!
