As you know, the floorboard is mounted on the fiberboard sheets laid on joists. For any violations in such places there is drawdown, the fragility of the coating. It is possible and the decrease in the strength of the sand backfill and thermal insulation. After strengthening these elements, the defect disappears.
In order to avoid spoilage it is impossible to cover the parquet with waterproof materials for more than five days. Parquet made of pine and larch is only valid in areas with эксплуа1ации which will not be intensive wear of the sexes. In the room you should lay flooring only from one wood species and one figure; the use of different color and size is only possible to create a special pattern.
Repair wooden floor
The characteristic lesions of floors from shpuntovannyh boards are abrasion, cracks, warpage. deflections and decay.
The increase in gaps between the blades, their warping and rotting often due to the use of unseasoned wood, and the creaking and camber from the wrong distribution of load-bearing lag, the poor performance of ties. It is also recommended to conduct a visual examination of: severing one Board, it is necessary to determine the distance between joists. When laying the floorboards with a thickness of 29 mm it should be equal to 400 mm, and the use of boards in the thickness 37 mm – 600 mm Quality ties you can check incised awl several parallel furrows and then across them at a 45° angle just a few more lines. If the angles at the intersections are not crumbled, the coupler is of high quality. In the presence of small gaps between the blades, you can do a slight facelift. To do this, the length of the cracks take a thin rail, a little wider the gap, the lower part stesyvajut at an angle (reducing the cone), then cover the sides of the carpenter’s glue and hammered with a wooden mallet or a hammer wrapped in a cloth to the floor level (Fig.3). After the operation, when the glue dries, you should shave the protruding part of the rail and paint the color of the coating.
Worse, if the boards have shrunk so much that between them over the entire area of the room formed (purpose. In this case, you will have to work hard: you must perform the bonding. Start the process with tidy remove nails. You need to flip the boards in the bottom margin of the surface of a log, and then the butt of the hammer to return them to their place, making the nails come out. Then the usual nail puller remove nails through a wooden substrate (it will prevent dents from the metal of the tool). It is recommended to remove the warped floorboards and replace them with the new extreme at the walls — can not touch, if the gap does not look out from under the baseboards, Then it is necessary to unite the parts by means of two wedges (Fig.4). Do not have to salvage all the coverage — enough to release four boards.
After rallying the floorboards need to nail up a length of 60 to 70 mm with a slope to the surface lat, zaglubit the hats dobojnikom or core. In the interval where the wedges, it is necessary to insert a Board slightly larger width (so that it is firmly sat down in her place) and just to nail her. If bonding is carried out from the wall, you can use several wedges with the substrate. The clearance from the edge of the Board to the wall should be 10 — 15 mm (Fig.5).
If the damage is only a small part of the fabric, the defective area can be carefully drill a small drill bit on the marked strictly across the Board lines, and then knock him out with a chisel. Then the same with a chisel need to make a saddle, beveled from two sides under an angle of 45°. The segment should fit down to the period of coverage. After brushing the edges of the bar carpenter’s glue, it is nailed to the saddle perpendicular to the bevel (Fig.6). The surface of the insert protruding above the floor level, you should shave.

Work on strengthening the sexes will be performed more efficiently if instead of nails use screws, however, as we know, they are much more expensive.
If the damaged area is large, you will have to change the whole Board or do the insert so that it relied on two joists. All rotten parts are necessarily removed, otherwise they will become! cause further destruction of the coating. In the presence of the floorboards of the lower ledge from the groove insert must be cut, and the top will fall on the crest of the adjacent boards (Fig.7).
You should pay attention to the logs. All damaged areas were removed and in their place a beat or fill with fresh inserts. In the process of dismantling the floor do not forget about processing the bottom of the cover with antiseptics. In the process of laying the boards need to thoroughly clean the surface of the screed from sawdust and shavings, as this debris can cause decay of wood.
The deflection of the floorboards indicates insufficient amount of lag or mismatch of the thickness of the boards standard. To solve the problem, you can put additional logs or to beat them across the support bars.
The creaking of the floor caused by friction of the side walls of planks or loose. The nails connecting the boards with the joists, it is necessary to bury with the help dobojnika or core. In the gap between boards can be filled with talcum powder, graphite powder or to hammer in wooden wedges, and if that does not work — tighten the screws, sinking their heads.
Diagonally, in the corners of the room, you should install special ventilation grids for ventilation of the space under the boards. Fencing of the gratings should be over floor level on 10 mm. so they do not spill water during washing of the coating (Fig.8).
After the panels are sealed, proceed to install the baseboards. Krepit them it is necessary not to the floor and to the wall. Previously along it for a distance of 1 m from each other at the attachment height of the plinth, drill a hole and hammer in wooden plugs. You can use dowels with plastic plugs-spacers.
For high-quality color the surface of the wooden floor you must protsiklevat. This is done with the help of special elektroshlifovalnaya machine or manual cycle. Tool pass through all places where the old paint was peeling like fruit or covered with cracks, and always along the grain of the wood. The treated area, polishing cloth, while grabbing and edges durable old color. They were then primed two coats of paint thinned with 10% white spirit of the Old coating prior to painting must be thoroughly cleaned of dirt, washed with 5% solution of soda ash (0.5 kg per 10 liters of water) or a solution of detergent, rinse with warm water and dry well. After the primer has dried the entire floor is covered with undiluted paint.
