Introduction
European Standards are currently available for
 - resilient, textile and laminated floor coverings
 - classification schemes, which define the characteristics of a location where a floor covering is to be used, and
enable an appropriate product to be selected.
For these products to give satisfactory service, they also need to be installed competently, and to receive
appropriate maintenance in service.
Certain countries have issued guides and/or standards that define good practice for installation and
maintenance.
To date, although there has been substantial trade in floor coverings between different countries in Europe,
these have largely been installed using the methods of the country importing them. Relatively little installation
work has been conducted across European borders, but it is likely that this will increase.
This Technical Specification is not intended to replace the existing national guides or standards on installation.
Its purpose is:
a) to identify a framework of good practice common to the existing national standards,
b) to identify the principal technical differences in approach between them,
and hence
c) to foster good standards of installation across Europe, including countries where there is no national
standard on
d) to enable a specifier to specify a common procedure for installation for work in his country, which may be
conducted by installers from other countries, and
e) to enable an installer to conduct work more easily in another country.

1 Scope
This Technical Specification provides recommendations for the installation of resilient floor coverings. It
covers products composed of polyvinyl chloride, linoleum, cork and rubber. It details suitable methods of
installation and advises on the selection of the materials required for their implementation.
The guidelines in this Technical Specification are intended for use in cases where manufacturer's instructions,
taking account of the national code of practice in the country where the installation is to be made, are not
available. References to the national codes that are currently available are listed in the Bibliography of the
various parts of this Technical Specification.
This Technical Specification is intended for use in conjunction with CEN/TS 14472-1 that deals with general
matters relevant to textile and laminate floor coverings as well as resilient floor coverings. It gives
recommendations for the installation of resilient floor coverings in new or existing buildings. It describes
common procedures which are in use throughout Europe and highlights the major differences that can exist in
different national procedures.
Special measures beyond those described in this Technical Specification may be necessary for the successful
installation of resilient floor coverings for specialist purposes such as electrostatic control or use in special wet
areas. These specialist techniques are not described in this Technical Specification.
2 Normative references
This Technical Specification incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text, and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to
this Technical Specification only when incorporated in it by amendment or revision. For undated references
the latest edition of the publication referred to applies (including amendments).
EN 12466 Resilient floor coverings – Vocabulary.
CEN/TS 14472-1:2003 Resilient, textile and laminate floor coverings – Design, preparation and installation
– Part 1: general.
3 Terms and definitions
For the purposes of this Technical Specification, the terms and definitions given in EN 12466, and CEN/TS
14472-1 apply, together with the following.
Specific national terms may be found in national glossaries or standards (see Bibliography).
3.1
underlayment
thin layer, applied to a screed to provide a smooth and/or flat surface to receive the floor covering.
4 Exchange of information
In order for the correct floor covering to be installed in appropriate conditions, at the right time, etc., it is
essential that all parties have a clear understanding of the requirements of the project, e.g. new build or
refurbishment, and of the implications for all concerned. To ensure that this is achieved, it is essential that
there is wide consultation between all parties involved in the project, including sub-contractors and materials
suppliers. This consultation should start early in the design stage but will be necessary throughout the
contract, especially should requirements or time scales change and as new sub-contract work is initiated. As
each project will be unique it is impossible to give a definitive list of the information to be exchanged, but the

typical examples, applying to textile and laminate floor coverings as well as to resilient floor coverings are
given in CEN/TS 14472-1.
5 Materials
5.1 Smoothing compounds or underlayments.
These materials are used to smooth uneven floors, or to improve the suction to assist the application of primers
or adhesives. The traffic and loads expected in service should be considered and an underlayment with
appropriate properties and classification should be selected for use in that area.
5.2 Underlayments
Underlayments may be selected from the following:
a) cementitious underlayment consisting of a specially formulated blend of cement, binder and fine
aggregate. The binder is commonly a natural rubber or synthetic polymer dispersion;
b) powder/water mixes based on casein/cement or polymer/cement and fine aggregate;
c) epoxy or other resin compounds (e.g. primer);
d) compatible underlayments that are available for direct contact with an anhydrite screed.
5.3 Underlays
Examples of products that may be used as underlays are:
- cork underlays (EN 12103)
- corkment (EN 12455)
- rubber-cork (EN 12103)
- studded polyvinyl chloride
5.4 Selection of floor coverings
EN 685 gives details of a classification scheme that relates the intended area of use to the different grades of
floor covering available. The client or specifier is recommended to use this standards to select an appropriate
specification of floor covering for the intended area of use.
Current European Standards for resilient floor coverings, and work currently in progress to prepare European
Standards are listed in the Bibliography.
Some of the standards under development are for floor coverings with a different composition to those covered
by current standards. The procedures described in this Technical Specification may not necessarily be
appropriate for these materials, and the recommendations of the manufacturer should be followed.
6 Subfloors
6.1 General
New subfloors should be constructed in accordance with the recommendations given in the relevant national
or European standards. Those responsible for the design and construction of the subfloor should ensure that it
meets the necessary requirements, i.e. should ensure that it has the characteristics to allow the floor covering

to be installed successfully before the installer of the floor covering is asked to commence work. These
characteristics include:
a) regularity of concrete floors and screeds;
b) moisture content of concrete floors and screeds;
c) integrity of screeds;
d) making-good of cracks;
e) treatment of construction joints;
f) gaps and changes of level;
g) moisture content of wooden subfloors;
h) presence of asbestos in an existing floor covering.
General information and guidance on subfloors is given in CEN/TS 14472-1 under the following headings:
  - materials;
 - details concerning concrete and screed bases;
 - moisture content of the subfloor;
 - timber bases;
 - levelling layer and underlayments;
 - existing floor covering.
A typical subfloor construction for a screed on a concrete base is shown in but not all levels represented will
be present in all installations. The damp proof membrane may be present either above or below the concrete.

Figure 1 — Layers of subfloor beneath floor coverings
New floor bases should be built in accordance with the appropriate national standards and codes, which are
listed in Bibliography.
The information on moisture content of the subfloor together with guidance on damp-proofing and eliminating
construction moisture is particularly important. New work in accordance with national codes can be expected to
be protected against rising damp by a damp-proof membrane, but the residual damp present in new concrete or
screeds can prevent satisfactory installation of resilient floor coverings.

NOTE Resilient floor coverings to current European Standards do not contain asbestos, but asbestos has been used in
some resilient floor coverings in the past, and may be present in the existing floor covering. In these circumstances, the
product should be handled and disposed of in accordance with the appropriate national requirements.
The following subclauses provide additional information and guidance on subfloors of particular relevance to
resilient floor coverings.
6.2  Board and strip floors
Where plain edged boards or tongued and grooved boards have been nailed to joists or battens, the use of
one of the fabricated substrates listed in 6.6 is essential. This will act as a buffer and thereby help to minimize
movement in the boards which might affect the appearance of the floor covering.
Uneven timber floors should be levelled by sanding, planing or by patch-filling with a suitable cement
underlayment before fabricated underlays are laid. Boarded floors nailed into joists secured by clips set in
concrete or dovetailed battens set in concrete, or boards nailed direct into concrete at ground level should be
adequately ventilated and protected by a damp-proof membrane.
6.3  Wood blocks
The laying of resilient floor coverings over bases of wood blocks can lead to problems. Any installation should
not be attempted unless the wood blocks conform to the following :
• the surface of the wood blocks is clean and free from wax;
• the condition of the floor is such that the blocks are sound and firmly bonded;
• the wood blocks are adequately protected against moisture.
If the resilient floor covering is to be totally adhered, consideration should be given to the possibility that the
blocks could lift from the subfloor during the life of the floor covering and also when the floor covering is lifted
for renewal.
The fixing of fabricated substrates listed in CEN/TS 14472-1:2003, 5.2.1 may help to provide a smooth level
surface. However, it is often found that the action of installing the underlay causes the blocks to fracture, or
the wood block adhesive to fail, particularly if it is embrittled by age. Because of the pr
