18、Switzerland and the United Kingdom. BS EN 15824:2009EN 15824:2009 (E) 4 Introduction The properties of external renders and internal plasters based on organic binders are primarily determined by the type or types of binders used and their respective proportions. Organic renders and plasters can be d
19、efined according to the: chemical and physical nature of the main active binder(s) and its state of dissolution, dispersion, or powder, which is decisive for the final characteristics of the surface covering with one or several coats; finishes determined by the aggregate distribution and application
20、 technique; properties and/or type of use. They are factory-made products produced in paste form, ready to use or in powder form. Renders and plasters do not attain their final characteristics until properly dried and hardened after application. The functions performed by renders and plasters depend
21、 on the properties of the type of raw materials used, on the thickness of the coats and the type of application. In addition, renders and plasters determine the final surface of the construction before eventually receiving a finish if required. The manufacturer designates the appropriate properties
22、and characteristics for end use and appearance and should give information about the use of the renders or plasters and the relevant conditions of use. BS EN 15824:2009EN 15824:2009 (E) 5 1 Scope This European Standard is applicable to factory-made renders and plasters based on organic binders used
23、for external or internal covering on walls, columns, partitions and ceilings. This European Standard is also applicable to renders and plasters with inorganic binders such as silicates, silanes, siloxanes and silicones. This European Standard contains definitions and final performance requirements.
24、It includes relevant characteristic categories to designate renders and plasters. This European Standard is not applicable to coating materials and coating systems according to EN 1062-1 and EN 13300. This European Standard does not contain recommendations for the design and application of renders a
25、nd plasters. However, this European Standard may be used for definition of renders and plasters in conjunction with codes of application and national specifications for execution of works. 2 Normative references The following referenced documents are indispensable for the application of this documen
