Specification for mortar for masonry - Part 1: Rendering and plastering mortar

This European Standard is applicable to factory-made rendering/plastering mortars based on inorganic binders for external (rendering) and internal (plastering) use on walls, ceilings, columns and partitions. It contains definitions and final performance requirements.
This European Standard provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard. The marking requirement for products covered by this European Standard is included.
It does not cover mortars where calcium sulphate binder is the principal active binding agent.
Calcium sulphate binder can be used as an additional binder together with air lime. If air lime is the principal active binding component, the rendering/plastering mortar is covered by this European Standard. If the calcium sulphate binder is the principal active binding component, the mortar is covered by EN 13279.
Special fire resistant- and acoustical mortars, mortars for structural repair and surface treatments of building elements such as materials for smoothing or trueing, paints, coatings, thin-layer organic renders/plasters and prefabricated units (e.g. plasterboards) are not dealt with in this European Standard.
This European Standard covers rendering/plastering mortars defined in Clause 3 with the exception of site-made rendering/plastering mortars. However, this European Standard or part of this European Standard may be used in conjunction with codes of application and national specifications covering site-made mortar.

Introduction
The characteristics of rendering and plastering mortars depend essentially on the type or types of
binders used and their respective proportions. Special properties can be achieved by the type of
aggregates, admixtures and/or additions used.
Rendering/plastering mortars are defined:
a) according to the concept as either:
1) designed mortar; or
2) prescribed mortar.
b) according to the mode of manufacture as either:
1) factory-made mortar;
2) semi-finished factory mortar; or
3) site-made mortar.
c) according to the properties and/or use, as either:
1) general purpose rendering/plastering mortars;
2) lightweight rendering/plastering mortars;
3) coloured rendering mortar;
4) one-coat rendering mortar;
5) renovation rendering/plastering mortars;
6) thermal rendering/plastering insulating mortars.
Rendering/plastering mortars do not attain their final characteristics until properly hardened after
application. The functions performed by a rendering/plastering mortar depend on the characteristics of
the types of material used, on the thickness of the coats and the type of application. In addition,
rendering/plastering mortars determine the surface of the construction.
Regional differences in construction practices and climate, and different constituents for
rendering/plastering mortars do not allow for the establishment of standard mix proportions for
prescribed mortar that would be applicable in all of Europe. Therefore, the specification of such mix
proportions (recipes) and fields of application should be based on practice and experience available in
the place of use.
1 Scope
This European Standard is applicable to factory-made rendering/plastering mortars based on inorganic
binders for external (rendering) and internal (plastering) use on walls, ceilings, columns and partitions.
It contains definitions and final performance requirements.
This European Standard provides for the assessment and verification of constancy of performance
(AVCP) of the product to this European Standard. The marking requirement for products covered by
this European Standard is included.
It does not cover mortars where calcium sulphate binder is the principal active binding agent.
Calcium sulphate binder can be used as an additional binder together with air lime. If air lime is the
principal active binding component, the rendering/plastering mortar is covered by this European
Standard. If the calcium sulphate binder is the principal active binding component, the mortar is
covered by EN 13279.
Special fire resistant- and acoustical mortars, mortars for structural repair and surface treatments of
building elements such as materials for smoothing or trueing, paints, coatings, thin-layer organic
renders/plasters and prefabricated units (e.g. plasterboards) are not dealt with in this European
Standard.
This European Standard covers rendering/plastering mortars defined in Clause 3 with the exception of
site-made rendering/plastering mortars. However, this European Standard or part of this European
Standard may be used in conjunction with codes of application and national specifications covering site-
made mortar.

requirements of this European Standard. The manufacturer shall keep records of how suitability of
materials is established.
5 Product characteristics
5.1 General
The requirements on characteristics for fresh and hardened mortar specified in this European Standard
shall be defined in terms of the test methods and other procedures referred to in this European
Standard. For these tests, the mortar shall be sampled in accordance with EN 1015-2.
The conformity criteria given in 5.2 for fresh mortar and in Table 2 for hardened mortar relate to
product-type determination (see 8.2) and consignment testing (see Annex A). For production
evaluation purposes the conformity criteria shall be defined in the factory production control
documentation (see 8.3).
NOTE The characteristics of mortar are specified under laboratory conditions and cannot always be directly
compared with the characteristics obtained under site conditions.
5.2 Characteristics of fresh mortar
5.2.1 Workable life
The workable life shall be declared by the manufacturer. When the rendering/plastering mortar is
sampled in accordance with EN 1015-2 and tested in accordance with EN 1015-9 the workable life shall
not be less than the declared value.
The workable life shall be tested only in the case of rendering/plastering mortars which contain
admixtures for controlling the setting, e.g. factory-made 'wet' mortar.
5.2.2 Air content
When relevant for the use for which the rendering/plastering mortar is placed on the market the range
in which the air content will fall shall be declared by the manufacturer. When sampled in accordance
with EN 1015-2 and tested in accordance with EN 1015-7 the air content shall fall within the declared
range.
For rendering/plastering mortar where porous aggregates are used the air content may alternatively be
determined by testing the fresh mortar density according to EN 1015-6.
5.3 Characteristics of hardened mortar
5.3.1 General
Different fields of use and exposure conditions require mortars with different characteristics and
performance levels. For this purpose, compressive strength, water absorption and thermal conductivity
shall be classified according to Table 1. The characteristics relevant to the intended use and/or type of
product shall be declared according to Table 2. The declared values and/or classes shall meet the
requirements specified in Table 2.
When relevant for the use for which the rendering/plastering mortar is placed on the market,
additional characteristics to those specified in Table 2 may be declared for each type of mortar where a
dash indicates 'no requirement’.
