Foreword
This document (prEN 13888:2008) 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 Unique Acceptance Procedure.
This document will supersede EN 13888:2002

Introduction
The characteristics of the construction products defined in this European Standard have to 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 grouts
should resist the degrading actions of climate, environment, etc.
Many properties of grouts for tiles are mainly determined by the type of binders used.
Tile grouts are defined in different types depending on the chemical nature of their binders.
The different types have specific characteristics in terms of 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 standard.
The manufacturer gives information about the use of the product and the correct conditions of use.
The specifier evaluates the state of the job site (mechanical, thermal and chemical influences) and chooses
the appropriate product considering all the possible risks.
1 Scope
This European Standard applies to ceramic tile grouts for internal and external tile installations on walls and
floors.
This standard gives the terminology concerning the products, working methods, application properties, etc.,
for ceramic tile grouts.
This European Standard specifies the performance requirements for cementitious and reaction resin grouts for
ceramic tiles.
This European Standard does not contain criteria or recommendations for the design and installation of
ceramic tiles.
NOTE Ceramic tile grouts can also be used for other types of tiles (natural and agglomerated stones, etc.), where
these do not adversely affect these materials.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 General
3.1.1
wall and floor tiles
tiles made out of ceramic or natural and agglomerated stones
3.1.2
grouting a tile surface
process of filling the joints between all types of tiles, with the exception of movement joints
3.2 Products
3.2.1
ceramic tile grout
any suitable product to be used to fill the joints between all types of ceramic tile
3.2.2
cementitious grout (CG)
mixture of hydraulic binding agents, aggregates, inorganic and organic additives
NOTE The grout has only to be mixed with water or liquid admix just before use.
3.2.3
reaction resin grout (RG)
mixture of synthetic resin, aggregates, inorganic and organic additives in which hardening occurs by chemical
reaction
NOTE They are available in one or more component forms.
3.2.4
liquid admix or latex additive
special aqueous polymer dispersion to be mixed with a cementitious grout on site
3.3 Tools and working methods
There are three possible working methods for filling the joints between tiles:
1) manually with a rubber float or suitable tool;
2) with an air pressurized- or handgun from a cartridge or an appropriate container (often done with
reaction resin grouts);
3) mechanically with a suitable machinery.
The cleaning of tiles after the application of the grout can be performed manually or mechanically with
appropriate tools.
