. Obligatory testing and exercise of due care

EGGER laminate flooring is manufactured in precise stages in highly-advanced and modern production facilities. Both finished and
ongoing products are subjected to regular stringent checks. Yet, despite quality controls, damage to individual boards, for example
during transport, cannot always be completely prevented. Therefore, it is a requirement to visually double-check each flooring
element before and during the installation job. Damaged or otherwise unsuitable flooring elements (products) must not be installed
and should be returned to the retailer and exchanged.

. Sub-floors

2.1

All sub-floors must be prepared for installation in accordance with regular sub-floor preparation procedures and accepted
tolerances within the flooring industry. Please consider the following points before beginning installation of laminate flooring
manufactured by EGGER. In case of failure to comply, all guarantee and warranty claims will become void.

Check the moisture level in the sub-floor:

Use a CM device to make sure the following levels are not exceeded:

 For cement-based screed ≤ 2 CM % – heated screed ≤ 1.8 CM %
 For calcium sulphate screed /calcium sulphate floating screed ≤ 0.5 CM % – heated screed ≤ 0.3 CM %
 These values apply to screeds without additives. With the use of additives and in case of fast-setting screed, the measurements

and limitis specified by the respective manufacturer shall apply.

 The test material must be obtained from the lower one-third of the screed. During this process, the thickness of the screed must

be measured and documented.

Check if the sub-floor is level:

The evenness test is based on common standards and takes place by placing a yardstick/straight-edge on the high points of the
surface and determining the gauge at the deepest location in relation to the bearing surfaces (measuring point intervals).
Use a max. 2 mm gauge (vertical deviation) at 100 cm intervals. Larger deviations should be addressed by suitable measures (e.g.,
with self-levelling compounds).

Check the load-bearing capacity of the sub-floor:

The sub-floor must be a sealed, self-supporting layer.

Check if the sub-floor is clean:

The sub-floor must be vacuum cleaned.

Check atmospheric conditions:

The following conditions should be met before, during and after installation:

 an air temperature of at least 18° C
 a floor surface temperature of at least 15° C
 a relative air humidity of between 40 % and 70 %

2.2

Laminate flooring from EGGER installed as a floating flooring configuration can be installed on all sub-floors which meet the above
described requirements. This includes in particular:

 all types of screed including hot water-heated screed
 chipboard constructions
 fibreboards
 existing floor coatings such as PVC, linoleum, natural stone slabs and ceramic tiles

Unsuitable sub-floors:

 EGGER laminate flooring may never be installed on textile floor coverings (e.g., carpeting) or sub-floors that are not properly

prepared for installation. In case of failure to comply, all guarantee and warranty claims will become void.

Sub-floors of limited suitability include:

 electrically operated underfloor heating (controlling the surface temperature)

Electrical underfloor heating systems are classified as sub-floors with limited suitability given that a range of film-based,
electrical heating systems are able to generate surface temperatures that significantly exceed 28° C. EGGER approves use of an
electrically operated underfloor heating system if it can be controlled digitally and the surface temperature can never exceed 28° C.
Furthermore, the heating system manufacturer must approve the use of the system in combination with laminate flooring.

Screed
If the laminate flooring system is installed floating on screed, you have to consider that possible residual moisture in the sub-floor
will seep to its surface. Consequently, all types of screed (with the exception of mastic asphalt) require, prior to the installation of
a system-specific insulating layer (see section: Attention! Underlay materials), a moisture protection film with an SD value ≥ 75 m to
be installed as vapour barrier over the entire surface & extend up the wall. When properly and professionally installed, the strips of
the moisture protection film must overlap 5 - 20 cm in the joining areas depending on the design.

Screeds with hot water floor heating
When building a heated flooring structure, all participants (builder, architect, heating specialist, heating technician, installer and
flooring manufacturer) must work together in a coordinated manner. All surface-heated flooring requires appropriate planning
and co-ordination for the heating system and screed in order to ensure maximum long-term performance without causing any
damage. The standard checks of the installation sub-floor must include inspecting the function of the floor heating / cooling system
(functional heating / cooling). Proof of the proper raising and lowering of the temperature of the heated screed structure in any
season must be provided and documented according to a protocol.

When heating the load and heat distribution layer, a distinction is made between functional heating and floor curing heating.

 Functional heating is the proof of the heating installer that a proper structure has been built and is used to verify the functionality

of heated flooring structures.

 Floor curing heating is the expelling of the residual moisture in the screed until installation suitability is reached.

Attention: Functional heating does not guarantee that the screed has reached the residual moisture required for installation
suitability. Therefore, installation curing is generally necessary.

Attention! The surface temperature of a heated floor structure may not exceed 28° C (83° F). EGGER laminate flooring is generally

installed floating. When installing on mineral sub-floors, it is absolutely necessary to install a moisture protection film with an
SD value ≥ 75 m as vapour barrier prior to the insulation underlay, on the entire surface and extending up the wall. During floating
installation, the heat conductivity of the laminate flooring and of the insulation underlay must be taken into account. The sum of the
heat conductivity values of all components must be ≤ 0.15m² K/W in line with EC requirements. When using insulating layers which
are not part of the EGGER accessories range, floating installation on heated screed voids all warranties in regards to compliance
with the effective, maximum allowable thermal transfer resistance of the overall structure.

Natural stone and ceramic tiles

Possible residual moisture in the sub-floor may rise to the surface (see section: Attention! Underlay materials), a moisture
protection film with an SD value ≥ 75 m must be installed as vapour barrier over the entire surface & extending up the wall.

Woodchip and fibreboard

A specially designed insulating underlay is recommended (see section: Attention! Underlay materials) should be installed. A
moisture protection film (vapour barrier) is not necessary.
