The answer is one. Proper way of gap filling for the original pine floor boards comes with clear resin mixed with the saw dust from the sanding process. Gaps with width of 5 mm can safely go with resin mixed with dust from 40 grit sanding run. Dust collected from finer grits is suitable for smaller gaps and usually used for gap filling parquet flooring with small gaps between the blocks.

There should be no flooring company with self-esteem promissing you the gap filling will be lasting for years on pine floor boards flooring or any planked flooring without tongue & groove system. That all depends on the solidness of the floor boards, how well they are fitted, their thickness and the condition of the joists - parameters all defining how stable the boards feel, as the only reason for the filling to come out could be a movement on the boards.

Strip Filling

Wider gaps are usually filled by pine timber slivers. Due to the number of occasions clients get eventually disappointed by the durability of the standard resin gap filling we get often calls with specific requirements for strip filling.

I always recommend to clients to consider as well the visual impact they will cause by going for strip filling on larger areas, as well as the cost, which may put the final price for your service significantly. In the end, with the restoration of our pine boards we all look at an affordable to bring the beauty and warmth of the planked wood into our home.
