What Are Wood Slivers?
GJP Floor Sanding uses specially manufactured strips of reclaimed pine, the strips are glued with a D3 PVA glue and hammered into the gaps before being chiselled off and polished back. To give you a more detailed overview of the process:
Re-nail floor, punching all nail heads into the floor 3-4mm deep
Clean joints out carefully, taking care not to catch any electric cables/water pipes, etc
Take the wedges (“Slivers”), place them into the joints (ie. the gaps between the boards) to check that the Sliver ‘seems at home’.
