Paints and varnishes. Coating materials and coating systems for exterior masonry and concrete. Determination of liquid water permeability | Status: Confirmed, Current

1 Scope This European Standard specifies a method for determining the liquid water permeability of coatings, coating systems and related products, intended for exterior masonry and classification according to EN 1062‑1. The method is applicable to coatings and coating systems on porous substrates such as brick, concrete and renderings. A liquid water permeability w of more than 0,5 kg/(m2 x h0,5) will not be accurately quantified by the test method described in this standard.
