Paints and varnishes - Coating materials and coating systems for exterior masonry and concrete - Part 3: Determination and classification of liquid-water transmission rate (permeability) EN 1062-3:1998

Publication date:   Aug 3, 2001

Scope

This European Standard specifies a method for determining the liquid-water transmission rate of coatings, coating systems and related products, intended for exterior masonry and concrete. The method is applicable to coatings and coating systems on porous substrates such as brick, concrete and renderings. The method is not applicable to coatings and coating systems having a coefficient of liquid-water transmission rate w of less than 0,05 kg/(m2 . h0,5).
