Before laying the lag, dry all materials at room temperature for 10-14 days.
Clean the concrete base and lay it on the roofing with an overlap of the wall about 10 cm.
If you want to put insulation with a thickness of 10 cm, under logs, you must install the retaining bars. They are installed with a step of 60 cm and fastened to the floor using screws with a length of 80-100 mm and dowels. If you are planning to install insulation or its thickness equal to 5 cm, it is possible to dispense with retaining bars and to lay the joists directly onto the roofing material.
After installation of the retaining bars start lag. Logs stacked reproach the direction of light from Windows at a distance of 350-500 mm from each other. The thinner floor Board, the less distance between the joists.
It is very important to align the joists horizontally, depends on the correct installation of all floor. The first lag puts from the highest point of the subfloor. Then, at a distance slightly less than the length of the level place the second lag and align them horizontally. To adjust the horizontal, you can use the lining of the roofing material.
Then between the two joists, install the following and be sure to align them using a level. Never lay the joists to each other, it may cause errors and incorrect installations in the future.
Stacked all the logs and making sure that they lie horizontally, proceed to the installation of lag. Attach them retaining the bars or roughing the floor with long screws.
Between the joists, lay the strips of insulating material. It will prevent the effect of "drum" when the floor will be laid. In addition, the floor insulation.
Now it is possible to lay the floor finish. If you plan to put in the room is ceramic tile or laminate, lay on the joists wrap or parchment paper. Across the joists, lay the rough floor of the planed boards. Planks are fastened to the joists with screws with a distance of 3-5 mm, in order to avoid the squeak. On top lay sheets water resistant plasterboard. Attach the drywall to the boards with screws vrazbezhku.
The gap between the drywall and fill the walls with foam. When the foam has hardened, cut it with a knife flush with the floor. Now you can lay tile or laminate in accordance with the technology.
Flooring is laid directly on the joists. The first Board laid the groove for a distance of 10 mm from the wall. It must be attached to each lag in two places. From the groove the screw is screwed at a distance of 30 mm from the wall. The bonnet recess, then she will be hidden under the baseboard. On the other hand the screw is screwed into the angle of the ridge at an angle of 45 degrees. Hat should drown.
On the Board are placed on the "tongue and groove" with the obligatory fixing to each lag.
Plank flooring after laying siluetta and processed in paint.
