Floor leveling for laminate, parquet or floor tiles.
Modern floor coverings are so simple inapplication, that any house master is able to independently make their packing. At the same time, a considerable part of the time is spent on the process of preliminary preparation, while the basic work takes quite a few hours. It should be noted that leveling the floor for a laminate, tile or parquet is an obligatory stage of repair. Especially if there are significant unevennesses, differences in height. Otherwise, the new floor covering will simply rise, and all work will have to be remade.
We lay the laminate. Leveling the floor in wet mode
Technology of adjusting the concrete foundation atThe help of the screed refers to the classic repair and construction works. Ready-made dry mixtures greatly facilitate the process. Note that the leveling of the floor under the laminate does not differ from the preparation of the base for laying parquet or ceramic tiles. Therefore, these recommendations can be safely used in any of these cases.
Before starting work, be sure to checkserviceability of all adjacent communications, since after flooring, access to them will be difficult. All cracks in the floor must be sealed with putty. It is also necessary to remove traces of rust, grease, paint and other impurities from the concrete surface. In addition, clean the concrete base with a vacuum cleaner.
The next step is priming. For this purpose, compositions with a PVA or acrylate base are used. It is most convenient to treat the surface from the spray gun. However, the paint roller is also quite fit.
To separate the screed and walls, along the perimeter of the building, lay strips of expanded polystyrene or slats wrapped in film.
The room, a width of more than five meters, break into small areas, laying in between the expansion joints.
In the presence of significant defects, the flooring under the laminate is made by beacons. Since there are some nuances here, I would like to talk about this in some detail.
To install the guide, use thea building level of at least 1.5 meters in size. The first beacon is installed at the highest point of the floor, at a distance of 20 cm from the wall. All the subsequent establish using the level, focusing only on it. The distance between the beacons depends on the length of the rule. For example, with its size of 1.5 meters, from the first to the second set aside 1.30 cm, for all subsequent - 1.45 cm, for the latter, the distance is taken up to 1.30 cm. The beacons are attached to the floor, most often , with the help of a rotband.
After the landmarks are established, it's time to start preparing the mixture for pouring. To achieve maximum uniformity, use a drill with a whisk attachment.
Ready solution is poured between the beacons anddistributed by rule. If necessary, individual places can be adjusted with a wide spatula (construction trowel). Before the complete setting of the solution, it is necessary to wait about two days.
As you can see, leveling the floor for a laminate is a simple process, but quite lengthy. It is most convenient to work in pairs. One prepares the mortar, the other aligns the screed.
Aligning a wooden floor for a laminate
Wet screed is good for new buildings, wherethe coating is completely missing. If there is a wooden floor in the room, it is more convenient to use another option. Dry screed allows in some cases to do without dismantling the coating. A slight height difference (no more than 1.5 mm per square meter) compensates the substrate for the laminate.
If the wood floor is in good condition, it isyou can confine yourself to cycling, with the subsequent adjustment and spreading of the gaps with the acrylic mixture. Old boards, too, do not rush to throw. Re-scraping and rebuilding the floor, you get a quality coating for a laminate or parquet.
Differences up to 10 mm are leveled with glue compositions based on PVA and sawdust.
Of course, a ramshackle as a "rough floor" is completely useless, so these elements need to be replaced with new ones.
There is another option for training,which uses only the lag between which the expanded clay is filled. Overlay sheets of chipboard or OSB of suitable thickness. Mounting is made on self-tapping screws designed to work with wood.
As you can see, the leveling of the floor under the laminate is quite easy. Saving money, time and nerves with this will be quite significant.
