Secret Nailing / secret nailed
------
Secret Nailing
This is the most common method of fixing a solid wooden floor.
It is suitable where a new plank floor is being fixed to an existing wooden floor, joists or softwood batons fixed to concrete and can be used as the sole method of fixing for traditional boards up to 150mm and Strata boards up to 200mm .
It involves driving a nail at an angle through the tongue of the floorboard into the wooden sub-floor, joist or softwood baton below ( Fig. 1).
