Should edge gaps be filled on new timber floors?
Here's the short answer:
Edge filling is generally not recommended on new solid timber floors except for parquetry, as expansion and contraction will crack rigid fillers at board edges. Nail hole filling with colour-matched filler is standard practice. FSA Network floor sanders know when filling is appropriate and when it will cause problems.
