Installation preparations
1.1 Acclimatization of the panels; Before starting the installation, the
flooring has to be brought into the room where it will be installed or in a room
with the same climate condition. The acclimatization will be carried out as
following: in sealed unopened boxes for a time period of at least 24 hours flat
laying with at least 50 cm distance to the walls at a room temperature of at
least 18°C at a floor surface temperature of a minimum of 15°C at a relative
humidity between 40% and 65%
1.2 Installation direction; flooring looks its best when the flooring panels
are installed parallel to the light coming in through the windows. The only
required installation direction is if you install flooring over hardwood
flooring boards. In this case you have to install the flooring at a 90 degree
angle to the existing hardwood flooring boards or apply a hardboard or plywood
sub floor.
1.3 Planning the first row; After determining the best layout of the flooring
and the starting wall, measure the width of the room and divide it by the width
of the flooring panels to determine the number of rows and the width of the last
row. If the last row is determined to be less than 60mm wide, it should be
adjusted by cutting the first row lengthwise.
1.4 Planning of expansion gaps; Since laminate flooring is made of organic
materials, it is subject to certain movement behaviors (shrinkage/expansion) due
to changes in climate conditions. It is necessary to leave gaps of 10mm for the
expansion in all parts of the structure i.e. walls, doorframes, stairs, around
pipes.
1.5 Planning of transition moldings; through the shrinkage and expansion
behavior of the flooring you have to install transition moldings in the
following areas: at all door throughways at all passageways single room length
and/or with more than 10 m (33 ft)
Installation Process
Check all panels for possible damages/defects. Ensure you understand the
difference between the tongue and the groove on the panel. Begin installing the
first row from the left-hand corner of the room with both tongue sides of the
panels pointing towards the wall. Place spacers between the edge of the flooring
panels and the wall to provide the correct space for expansion.
Connect the second panel to the first by indirectly tapping using a hammer
and push block, thereby joining the boards’ headers. Mark the last panel in
the first row to the required length (place tongue to tongue) and cut. Start the
second row with the off cut from the last panel of the first row. Always make
sure the off cut is at least 500 mm long, if not then cut another piece which is
greater than 500mm long. Start all subsequent rows with the off cut piece from
the previous row. Connect the second row to the first by placing the
interlocking end of the new panel at an angle to the previously installed panel
and then lower it into a horizontal position to lock then indirectly tapping
using a hammer and push block, thereby joining the boards’ headers.
Attention! A floor is considered level if the deviation height is less than
2mm over a distance of 2.5 linear metres. Deviations above this level must be
levelled out before laying the underlay.
