Paints and varnishes - Coating materials and coating systems for exterior masonry and concrete - Part 3: Determination of liquid water permeability

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.

Beschichtungsstoffe - Beschichtungsstoffe und Beschichtungssysteme für mineralische Substrate und Beton im Außenbereich - Teil 3: Bestimmung der Wasserdurchlässigkeit

Diese Europäische Norm legt ein Verfahren zum Bestimmen der Durchlässigkeit für Wasser (Wasserdurch¬lässigkeit) von Beschichtungen, Beschichtungssystemen und ähnlichen Produkten für mineralische Untergründe im Außenbereich zur Einteilung in Klassen nach EN 1062-1 fest.
Das Verfahren ist anwendbar auf Beschichtungen und Beschichtungssysteme auf porösen Untergründen wie Mauerstein, Beton und Putzen.
Eine Wasserdurchlässigkeit w von mehr als 0,5 kg/(m2 - h0,5) lässt sich mit dem in dieser Norm beschriebenen Prüfverfahren nicht exakt bestimmen.

Peintures et vernis - Produits de peinture et systèmes de revêtements pour maçonnerie et béton extérieurs - Partie 3 : Détermination de la perméabilité à l'eau liquide

La présente Norme européenne spécifie une méthode de détermination de la perméabilité à l'eau liquide des
produits de peinture, systèmes de revêtement et produits assimilés, appliqués sur maçonnerie et béton
extérieurs et classés conformément à l’EN 1062-1.
Cette méthode est applicable aux produits de peinture et systèmes de revêtement pour supports poreux
comme par exemple la brique, le béton et les enduits.
La méthode décrite dans la présente Norme ne permet pas de quantifier avec exactitude les coefficients de
perméabilité à l'eau liquide w supérieurs à 0,05 kg/(m2 x h0,5).

Overview

EN 1062-3:2008 is a CEN European standard that specifies a laboratory test method for determining the liquid water permeability of paints, varnishes, coating materials and coating systems intended for exterior masonry and concrete. It is designed to support classification under EN 1062-1 and applies to coatings on porous substrates such as brick, concrete and renderings. Note: the method cannot accurately quantify very high permeability values (w > 0,5 kg/(m²·h0,5)).

Key topics and requirements

• Scope and purpose: Measures liquid water transmissibility (w) of coating systems on porous mineral substrates for exterior use and provides data for EN 1062-1 classification.
• Substrates: Typical substrates include calcium silicate bricks, clay bricks or mortar slabs. Test blocks must be ≥ 200 cm² and ≥ 2.5 cm thick and have a substrate water absorption coefficient (EN ISO 15148) > 1 kg/(m²·h0,5).
• Specimens and replication: Minimum of three test specimens (more recommended to detect outliers).
• Preparation:
  • Apply coatings per manufacturer instructions and dry (minimum drying and specific conditioning steps).
  • Seal reverse/edges (e.g., two coats epoxy) leaving test surface exposed with a 5–10 mm overlap.
• Aging / conditioning: Three cycles of 24 h immersion in potable water at (23 ± 2) °C followed by 24 h drying at (50 ± 2) °C to simulate outdoor ageing and leaching, with final conditioning in standard atmosphere (23 ± 2 °C, 50 ± 5 % RH).
• Test apparatus: Water container, oven capable of (50 ± 2) °C, balance (0.1 g resolution up to 2000 g), specimen supports.
• Procedure: Immerse coated face 5–10 mm below water surface; record mass gain at intervals (recommended: 10 min, 30 min, 1 h, 2 h, 3 h, 6 h and 24 h).
• Expression of results: w (kg/m²·h0,5) = mass increase (kg) / area (m²) / sqrt(time). Use arithmetic mean of at least three results for EN 1062-1 classification.
• Precision: Repeatability ~10% (within lab), reproducibility ~15% (between labs).
• Reporting: Include reference to EN 1062-3:2008, product ID, specimen count, coating system details, substrate type/dimensions, individual and mean results, classification, deviations and observations.

Applications and users

This standard is essential for:

• Coating and paint manufacturers - product development, quality control and performance claims for exterior masonry coatings.
• Independent testing laboratories - accredited testing and certification to support CE marking or performance declarations.
• Architects, specifiers and contractors - selecting coatings with verified resistance to water ingress for façades, brickwork and concrete repairs.
• Regulatory bodies and certifiers - product classification, compliance checks and comparative performance assessment.

Practical benefits include reliable, repeatable measurement of liquid water permeability to inform specification, durability assessment and selection of exterior coatings that reduce rain-driven moisture ingress.
