Resin & Sanding Dust
The conventional way of filling very fine gaps or small nail holes.
This filling is used especially in very fine gaps in parquet flooring.
The resin is mixed with the sanding dust that comes off the floor. The sanding dust colours the resin to make a filling paste the same colour as the floor.
The professional way to fill the gaps in pine floorboards.
Although with Pine floors the gaps often help retain their character, and in rooms upstairs, allow heat to pass through.
Draughtex is a black or grey rubber strip that can sit in and just beneath the gap of the floor, or level
with the floor.
