European foreword
This document (prEN 12004-3:2021) has been prepared by Technical Committee CEN/TC 67 “Ceramic
tiles”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document with FprEN 12004-1:2021 will supersede EN 12004-1:2017.
In comparison with the previous edition, the following technical modifications have been made.
Splitting the former document into two parts:
— Part 1: Adhesives for ceramic tiles – Essential characteristics and AVCP;
— Part 3: Adhesives for ceramic tiles – Terminology, specifications, designations and marking.
The series of EN 12004 consists of the following parts, under the general title of Adhesives for
ceramic tiles:
— Part 1: Adhesives for ceramic tiles – Essential characteristics and AVCP
— Part 2: Adhesives for ceramic tiles – Test methods
— Part 3: Adhesives for ceramic tiles – Terminology, specifications, designations and marking

Introduction
It is essential that the characteristics of the construction products defined in this document consider that
the normal stresses due to the works for which they are intended, assembled or installed, can be properly
accommodated. Some special characteristics will take into account the type of substrate and that the
adhesives should resist the degrading actions of climate, etc.
Many properties of adhesives for tiling are mainly determined by the type of binders used. Different types
of tile adhesives are defined according to the chemical nature of their binders.
The different types of adhesives for ceramic tiles have specific characteristics in terms of their application
properties and final performance.
The relationship between characteristics and the working conditions (dry or humid conditions, hot
climate, fast setting, etc.) is not given in this document.
The manufacturer should give information about the use of the product and the correct conditions of use.
The specifier should evaluate the state of the job site (mechanical and thermal influences) and choose the
appropriate product considering all the possible risks.

1 Scope
This document specifies the additional characteristics for the adhesives for ceramic tiles, i.e. cementitious
ones for internal and external tile installations, dispersion and reaction resin ones for internal tile
installations, on walls and floors.
This document provides the terminology concerning the products, working methods, application
properties, etc., for ceramic tile adhesives.
This document does not provide criteria or recommendations for the design and installation of ceramic
tiles.
NOTE Ceramic tile adhesives are also used for other types of tiles (natural and agglomerated stones, etc.), if
they do not adversely affect these materials.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at https://www.electropedia.org/
• ISO Online browsing platform: available at https://www.iso.org/obp
3.1 General
3.1.1
thin bed method
method used for installing tiles onto a plane surface with an adhesive
Note 1 to entry: The adhesive is usually applied with a trowel to obtain a layer and then combed with a notched
trowel to achieve the right thickness and planarity.
3.1.2
fixing surface
plane rigid surface upon which the tile is fixed
3.1.3
wall and floor tiles
tiles made out of ceramic or natural and agglomerated stones
3.2 Products
3.2.1
cementitious adhesive
mixture of hydraulic binding agents, aggregates, and organic additives, mixed with water or liquid admix
just before use
3.2.2
dispersion adhesive
ready to use mixture of organic binding agent(s) in the form of an aqueous polymer dispersion, organic
additives and mineral fillers

reaction resin adhesive
one or more component mixture of synthetic resin, mineral fillers and organic additives in which
hardening occurs by chemical reaction
3.3 Tools and working methods

notched trowel
toothed tool, which makes it possible to apply the adhesive as a series of ribs of a uniform thickness onto
the fixing surface and/or the reverse face of the tile
3.3.2
floating method
adhesive applied only to the fixing surface, usually with a trowel to obtain a uniform layer and then
combed with a notched trowel

floating and buttering method
adhesive applied to the fixing surface and to the reverse of the tiles

time of storage under stated conditions during which an adhesive is expected to maintain its working
properties
3.4.2
maturing time
interval between the time when the cementitious adhesive is mixed and the time when it is ready for use
3.4.3
pot-life
maximum time interval during which the adhesive can be used after mixing
3.4.4
open time
maximum interval after application at which tiles can be embedded in the applied adhesive and meet the
specified tensile adhesion strength requirement
3.4.5
wetting capability
ability of a combed adhesive layer to wet the tile
3.4.6
slip
downward movement of a tile applied to a combed adhesive layer on a vertical or inclined surface

maximum time interval after which the tile’s position in the adhesive layer can be adjusted without
significant loss of adhesion strength
3.5 Final properties
3.5.1
adhesion strength
maximum strength per unit surface area which can be measured by shear or tensile testing
3.5.2
deformability
capacity of a hardened adhesive to be deformed by stresses between the tile and the fixing surface
without damage to the installed surface
3.5.3
transverse deformation
deflection recorded at the centre when a beam of hardened adhesive is subjected to three point loading
