    Laying a laminate floor over osb. There is depression on the floor that is 8mm deep at the worst spot. It forms a channel near where two boards join. How do you recommend I fill it? It’s about 30cm long 20cm wide. See attachment.

    Wood filler, levelling compound, perhaps even tile adhesive if you have time to let it dry before flooring.

    I’ve plenty of time. I’d like to do it right. I have tile adhesive, would you recommend that? I even have primer for it.

    I'd lift the OSB, andmget the joists underneath level with a strip of wood, and put the OSB back down. Use glue and a few tacks to attach the strip of wood do it doesn't squeak. Is you have a track saw/table saw it's an easy job.
