Filler for chipboard floor?

Ant555

What can I use as filler on a chipboard floor?

Floor upstairs is chipboard - I had to take up a board in the centre and unfortunately I made a real mess of it.
All back down now but there are hollows and areas that need 'filling' where the edges came apart when I pulled it up. Not gaps or holes that go all the way through to the void but areas/strips that are not now level.

As its a floor and an area that will be walked on - what do people suggest might be best as a filler to being the troughs up to the same height as the main floor?

A picture of my handiwork here - I should have taken a pic when the panel was back down but you can see its the bit on the edge that will need filling

Try a joiners shop to get some sawdust & mix it with pva/wood glue to fill in

The two part fillers are like a plastic resin and the ones I've used set really hard, so I'd go for them over the PVA ones.

One thing I'd check because you can't see from the photos easily, is that its just surface damage and that it hasn't gone deep enough to weaken the boards.

Thanks for all the replies.

The suggestions about sawdust and pva glue seemed like what I needed but had no idea where I would easily get a load of sawdust from until watching that video - pet supplies!
