- Before installing the floor covering, always read and follow installation instructions.
- Wooden flooring is not installed in unheated areas, damp areas or external surfaces. The exceptions are specifically manufactured wooden flooring for external surfaces and thermally treated wood for damp areas.
Consult your flooring salesman regarding the installation of wooden floor covering into damp areas.
- Wood is a natural material, so the boards may vary in colour. Before the installation the boards must be checked and a nice pattern must be formed.
- We recommend mixing the boards (plates) from different packages when placing them. (This applies to all types of flooring.)
- Every board or plate must be visually checked and controlled before placing. The boards that are unsuitable must be separated, discarded or used on less visually exposed areas. The package may have a specific share of shorter boards.
- The flooring is usually placed in the direction of the main source of light.
- After the flooring has been placed, it will eventually expand and shrink, so appropriate space must be provided near the walls and other objects or obstacles; the distance from the wall should be at least 10 mm, whereas in bigger areas and rooms with unstable climate this interval must be bigger. Expansion joints must be particularly big when dealing with massive parquet.
- In larger areas (see the flooring manufacturer instructions, usually stating the width > 7m and length l > 8m) and near the passages the expansion should be anticipated, particularly with the floating installation.
- Before the installation the floor covering should be stored in its original packaging for at least 48 hours so that it adapts to the area, in which it shall be placed.
- The packages are opened directly before the installation and the ones that will not be used should be repacked.
- Massive and 2-layer parquet must be placed and glued across the entire surface; 3-layer parquet is intended for the floating installation and can also be glued onto the floor. Laminate and vinyl flooring, cork and linoleum on a HDF board must be used for the floating installation. Vinyl flooring plates LVT are used for the floating installation or they are glued (depends on the type).
- During the installation the air temperature must be between 15 in 18°C. Relative air humidity before, during and after the installation should be between 50 in 65 %.
Subfloor – general
- The subfloor for flooring installation must be flat, hard and compact. If it is not appropriate, it must be corrected. The subfloor onto which vinyl, PVC and linoleum floor coverings are glued must be preliminary treated with a levelling compound.
- The screed must be cleaned before the installation.
- Resilient (old) flooring is not a suitable base. Old PVC coverings, linoleum or cork may be suitable for the floating installation, but only if they are glued to the subfloor across the entire surface.
- Old ceramic tiles are a suitable base only if hydroinsulation is ensured. In order to glue across the old ceramic, the ceramic must be well cleaned and roughened and an old adhesive or a leveling compound should be used.
- The humidity must not exceed the following values:
- cement screed (CM method) 2,0% (1,8% – underfloor heating)
- anyhdrate screed (CM method) 0,5% (0,3% – underfloor heating)
- wooden subfloor 8,0%
Humidity content must be taken into consideration, particularly in new constructions.
These are the general instructions; always follow the instructions of the flooring manufacturer.
