The laying of nailed parquet uses a variety of techniques. You will have to handle the wood but can also be plaster. It is therefore longer and more difficult to achieve. You will also need more equipment.

Laying a nailed parquet

The implementation is carried out in two stages: first the installation of the joists then that of the parquet, nailed on the joists.
The extra thickness compared to your original floor will be about 10 cm; which can be a problem in renovation.
To ensure enhanced sound insulation, it is possible to lay a resilient strip under the joists and to unwind between them a mineral wool.

The joists

Fixing the joists

The joists are pieces of wood, usually coniferous (pine or fir) placed perpendicularly to the direction of the beams and floorboards.
They are spaced 45 cm apart in the case of 23 mm thick blades and 30 cm maximum with 16 mm blades. When laying, you can make up for irregularities in the surface of the support by placing shims under the joists. To fix them, you can:
• pegs (most practical solution),
• nail them (on screed or old parquet),
• seal them with plaster pads (the oldest and most economical technique, but it is necessary to wait for dry plaster before laying the parquet).

The steps of laying parquet

Nail a parquet on a joist

  • Report the location of the joists on the slab with a line.
  • Then fix these pieces of wood every 25/30 cm with dowels to hit.

Laying the first parquet board on the joist

  • Begin laying by sliding wedges against the wall.
  • Always observe a joint about 5 to 8 mm around obstacles and walls.

Nail a parquet on a joist

  • To nail the blades on the joists, use "man-headed" points inserted at an angle into the tongue.

Successfully laying nailed parquet

  • Hunt the heads of the points with a nail punch so as not to interfere with the casing of the next floorboard.

Laying the second blade of nailed parquet

  • Lay the second row of blades.
  • Make sure the ends of the blades are always connected over a joist. Otherwise the floor may collapse under the feet.

Using a martyr wedge for laying parquet

  • Engage the blades with a matyred wedge (blade fall or wedge grooved) and a hammer to avoid damaging the tongues of the blades.

Using a hunt for laying a parquet

  • The last blade is nested and tightened using a metal flush before being nailed over it (the nail will then be concealed by the plinth).
