When the walls are ready and the roofing works are finished, there is the question is, it is often necessary to lay the floor on the logs with your own hands in living room. This simple technical process consists of several stages.

  • Installation lag.
  • Laying insulation (this step is necessary if the room is used in the cold season).
  • Mounting the finishing board.

How lags are attached

Logs of the floorLags of the floor

Logs are the boards on which the material of the finished ready is mounted. gender. What should be these bars? It will depend on what’s under the lags. The basis may be a different type of soil, concrete and wooden beams. The design is also affected by whether insulation and vapor barrier are used.

Regardless of the base, lags should always be processed antiseptic, that is, a solution that protects from insect pests and decay.

If the installation of the lag will be carried out on the ground, it is necessary create concrete posts for fastening. For this in the earth 50-60 cm deep holes are dug, at a distance of 80 cm from each friend. For convenience, marking can be done with a tense fishing line. or kapron cord in places where the logs lie.

Here’s how to make the pillars:

  1. At the bottom of the pit, which has a square appearance of 50 by 50 cm, pour a pillow of sand 10 cm thick, and then 10 cm of crushed stone.
  2. Then a wooden formwork is made of the required height, usually not less than 20 cm above ground level. If the soil is loose, it is better to additionally use reinforcement for strength.
  3. Finished formwork with recesses can be poured with concrete mortar with a ratio of cement, sand and gravel 1: 3: 5 or 1: 2: 4. IN top of columns after pouring concrete before setting it is necessary to implant threaded rods for fixing the lag.

The supporting upper part of the columns must coincide with horizontal line of the measuring level.

After the concrete has set, a layer is placed on top of each column. roofing material for waterproofing. Making sure the studs are solid in concrete, you can use them to fix the lags that will put on these studs through pre-made holes. The diameter of the holes should be such that they freely pass into it. studs but not dangling. Also need to do at the top of the lag “sweat” for a nut with a washer. Then on the logs worn on the studs, it is possible to wind nuts with washers, while simultaneously pressing the lags to the upper plane of the columns.

Draft floorRough floor

If you need to do insulation and a vapor barrier, then to the lower side part of the lag is mounted supporting block. A rough draft is mounted on it. board for laying a vapor barrier and insulation.

For a vapor barrier it is necessary to use special material, but not simple film. It should be a diffuse membrane that displays accumulated condensate, or other similar building material.

Thermal insulation is placed on top of the vapor barrier. It could be mineral wool, basalt cotton wool or something similar in property (Rockwool building materials and more). From top level insulation to a clean floor should be an air gap of 1-2 cm for ventilation.

Flooring

Grooved boardTongue and groove board

For a clean floor, use a grooved board, which has a spike-groove system, that is, on one side it is located spike, and on another narrow recess or groove into which it will be tight enter the spike of the next board.

All wood flooring materials must be pre-installed. well dried.

Wood flooring always starts from the far side premises. After the board has been laid across the lag, it is necessary push it close to the wall. Then necessary between the wall and place a gasket 2 cm thick on the board, after which fix the board with screws. Screw one into the edge near the wall a self-tapping screw on top of the board, which will hide under the baseboard. With side the open side of the board should be screwed directly into the groove at an angle 45º.

Then, the spike of the next board is inserted into this groove. Knocking down with a mallet a board (mallet – a hammer with a rubber or wooden knob), you can continue to twist the screws into the groove, observing the step between them. Then the gaskets between the wall and the board are removed. As a result around the entire perimeter there is a gap of about 2 cm between the floor plane and an adjacent wall – it is needed so that the tree can breathe freely. During the year, air humidity will change, and clearance will prevent deformation of the floor plane.

An alternative to a grooved board can be sheets of chipboard, plywood and OSB. Their advantage is greater speed due to space overlap. In addition, as a result, fewer joints remain. Therefore these materials are good if it is later planned to lay a laminate or linoleum.

Such chipboards are screwed to the lags from above. For the self-tapping screw, a depression is made, “sweat” so that the head of the self-tapping screw protruded above the plane of the finishing floor. Then all these recesses must putty. You should also do with the joints of the plates. However joints must be puttied with acrylic sealant, otherwise, if applied non-ductile putties, subsequently they crack and crumble. And over time, all these grooves and seams will appear in the form scuffs on linoleum, because of which decorativeness will be impaired general view.

When choosing material for the floor, do not forget about one important aspect: the thinner it is, the narrower the gap between the lags. TO for example, if the thickness of the laying material is 20 mm, then the space between the lags should be no more than 30 cm. From this the strength of the floor will depend.

Using these tips, you can confidently take on styling work gender. Successful work!
