scope:

NEN-EN 16566 defines coating materials designed to cover all backgrounds and substrates in traditional materials or compliant with the standards in force, whether new or existing, bare or coated, absorbent or non-absorbent, smooth or rough, in order to prepare them to receive a paint or related system, or a bonded cover, whether specific or not. More generally intended to improve the surface appearance, they can also: - not be over-coated; - create a textured appearance or not; - be treated/coloured or not (pigments, wax, etc.). Exterior fillers are not intended as top coat. Interior coating materials with grain size over 1 mm are not covered by this European Standard. Fillers specifically intended for wooden and metal substrates are not covered by this European Standard. This European Standard complies with the general system for classification of water-borne coating materials and coating systems for interior walls and ceilings described in EN 13300. This European Standard complies with the general system for the description of coating materials and coating systems for exterior masonry and concrete described in EN 1062-1. The essential function of fillers covered by this European Standard is therefore a decorative function. Therefore, these fillers are considered here as preparatory and/or decorative fillers, of smooth or textured appearance.
