Principles of assembly and use

SWISS KRONO laminated floor panels are intended for use as a finishing material for floors in residential and public premises characterized by a stable climate. Optimal conditions are temperature: 16 – 22ºC, relative humidity: 40 - 65%. 

1. Laminated floor panels should not be installed in areas where the level of humidity exceeds 65%, i.e. bathrooms, saunas, laundry rooms, etc.

2. SWISS KRONO laminated panels can be installed in rooms with an underfloor water heating system.

3. Floor panels of AC3 abrasibility class can be installed in residential premises with medium traffic loads.
Floor panels of AC4 abrasibility class can be installed in residential premises with high traffic loads and in public premises with low traffic loads.
Floor panels of AC5 abrasibility class can be installed in residential premises with high traffic loads and in public premises with medium traffic loads (excluding dance halls, sport halls, etc.).

4. Floor panels must be installed in compliance with the assembly instructions, in closed rooms which will be heated to room temperature in the winter (an assembly manual is provided on the label attached to the package of floor panels or on the bottom of the carton). 

5. Assembly of laminate floor panels requires the following tools and materials:

  • an approved PE vapour barrier film ≥ 0.2 mm
  • a levelling board designed for use under floating floors, e.g. levelling foam (with thickness up to 3 mm), underlayment boards,  
  • assembly kit (pull-bar, spacers),
  • fine-toothed saw,
  • level with a minimum length of 1.5m,
  • pencil, ruler, measuring tape, adhesive tape resistant to moisture,
  • MDF baseboards and accessories for assembly and finishing.

6. The base for laminated floor panels must be flat, dry, stable, clean and flush (unevenness may not exceed 2 mm per 1 meter of base). Always cover the prepared base with an approved PE vapour barrier film with a minimum thickness of 0.2 mm and an overlap (approx. 15 cm). Joints must be fixed with a moisture-resistant adhesive tape. Vapour barrier film should also be used when mounting the panels on an underfloor heating system. The film must be placed on the walls up to the height of the top edge of the baseboard. Now the levelling underpad can be laid. During assembly, please follow the instructions of the underpads’ manufacturer.

7. Original packed panels before assembly should be subjected to 48 hours of acclimatization in the conditions of use (min. 16ºC, humidity 40 - 65%).

8. Before and during assembly each floor panel should be checked for damage and/or visible faults. Ensure sufficient lighting. 

9. The assembled panels form a so-called floating floor. They cannot be glued, nailed or fixed to a base and/or walls (except for stairs) in any other way.

10. For best visual effect, the floor panels should be placed in line with the primary source of light (perpendicularly to a window). 

11. Ensure a space of 10 mm (extension gaps) between the floor and all stationary elements (pillars, thresholds, doors, pipes, walls, doorposts, etc.). Spacers should be used as the floor panels will expand or contract due to changes of temperature and humidity. 

12. Prior to assembly it is necessary to calculate the width of the last row of panels. The width should not be less than 50 mm. If this width is smaller, the first row of panels should be cut appropriately.

13. While installing floor panels with a thickness of 6 to 10 mm in a room with a length greater than 8 m or with a width greater than 6 m, extra expansion gaps (1 - 2 cm wide) should be made in proportional sections of the floor. The gaps are masked with special strips. The strips should not be nailed, screwed or glued to the panels.

Floor panels with a thickness of 12mm can be installed without additional expansion gaps on a surface of 10m to 12m.

14. Maintenance: dirt should be removed with a brush or vacuum cleaner with a brush end. The floor may be cleaned with a damp (not wet) cloth (flat mop) with use of a care product for laminated panels recommended by the manufacturer. In no case should water be poured on the panels, nor should they be cleaned with wax, steam, polishes, concentrated detergents or cleaning powders.

15. After the floor has been laid, it must be protected at the entrance to the room against the harmful effects of sand or humidity with the use of appropriate doormats or carpets.

16. The floor panels are resistant to abrasion caused by furniture castors only in respect of rubber lined castors. The use of furniture with plastic or metal castors (rolls) without suitable protection mats will lead to floor damage and voiding of the warranty. 

17. Felt pads should be placed under the legs of chairs, tables and other furniture. The pads should be cleaned regularly. Unprotected furniture must not be moved across the surface of the panels.

18. NOTE. Water spilled on the panels must be removed immediately.

19. Please remember that the laminated floor panels show an image of natural wood and, like wood, they may differ from one another by the irregular pattern of the rings, their shades and occurrence or absence of knots of various shapes and colours. Such differences are not a defect of laminated panels.  

20. Allowable discrepancies in height between panels - max. 0.15 mm - and gaps between panels - max. 0.20 mm – as provided for by the EN 13329 norm are allowed.

21. The milled technological profile which may be present on the underside of a floor panel does not affect the strength and functional characteristics of the product.
