The advantages of laminate as an outdoor coating consist in practicality, the rapid way of laying, relatively low prices. In addition, laminate is environmentally safe during operation and is represented by a wide color range capable of satisfying any requests. But simplicity of laying and long service life is directly dependent on the quality of the material and the proper training of the floor, the use of the substrate.
The consequences blew the laminate of the unprepared surface
Laying the laminate on the uneven surface will lead to premature coating wear, loss of aesthetic species. Are dangerous areas on which removal, tubercles, height differences are present. In places of attachment of locks, both transverse and longitudinal, the load increases, creaps appear. In the process of operation, the cracks are expanding due to dust and moisture, the edges will swell. The inevitable result becomes loosening, which leads to a breakdown of locks in places of large deflection and continuous load.
The first defects begin to appear in a year, gradually accumulate and become noticeable for the eye . The surface loses aesthetic appeal, troubleshooting is required. Possible problems associated with laying material on an uneven surface:
- short service life, not more than 1-3 years,
- Discrepancy of locks on uneven areas, dipping dirt and moisture in the grooves,
- When walking on the floor, creap appears.
It is important: excluding unpleasant consequences will help not only the leveling of the base, but also the use of substrates that perform sound and thermal insulation protection.
Alignment of irregularities substrate
Minor differences are easily eliminated by a soft substrate, specially manufactured for laminate. The porous structure retains heat, performs the role of sound insulation. Thanks to the use of the substrate, the service life of the floor cover increases, the installation process is faster . The basis for substrates are:
- polyethylene, specially foamed,
- polyurethane fiber,
- cork material
- Combined cork and bitumen composition.

Important: Permissible drops when laying the floor before laying laminate not exceed 2 mm / PM.
If the surface has visible defects or differences are more important, it is required to align.
Concrete floors: how to fix irregularities
Laminate, laid on an uneven concrete base, does not save even the substrate. A couple of years such a coating will serve, but then it will be necessary to replace. For alignment of concrete floors, self-leveling formulations are used, for example, leveling.
Alternative solutions use plywood sheets. Before the flooring plywood exhibit lags using the level for checking, sheets are fixed with self-draws.
Aligning wooden surfaces
Wooden bases necessarily require preparation, otherwise the coating will not last long. In addition to alignment, it is necessary to eliminate surface defects.
- The slots between the floor and cracks are putty,
- The failed floorboards appear as a result of rotten or broken lag. It will be necessary to parsing the floor and replacing the lag to the new, the return of the flooring in place, replacing new,
- Deformed areas, creaky floor. Perhaps it will take a hauling and surface grinding.
Laminate flooring on the uneven floor threatens problems during operation, the costs of re-conducting work. A solid approach to the alignment of sex and eliminate defects guarantees the durability of the use of floor covering.
