EN 14891 Liquid Applied Waterproof Products for Use Under Ceramic Tiles Bonded with Adhesives

In the European standard EN 14891, requirements, test methods, stability of performance for all liquid applied waterproofing products based on polymer modified cementitious mortars, dispersions and reaction resin coatings used under ceramic tiles for outdoor tile installations on walls and floors and in swimming pools. evaluation and verification, classification and marking principles.

This standard gives product terminology and describes test methods and performance requirements values ​​for liquid applied waterproof products associated with tile adhesives.

This standard also covers the conformity assessment, classification and naming of waterproof products with liquid applied under the ceramic coating. However, it does not contain recommendations for the design and installation of ceramic tiles and grouting together with waterproof products.

Liquid-applied waterproof products are also used under natural stones and other similar types of tiles, so as not to adversely affect these materials.

This standard does not purport to address all relevant safety problems for use. It is the user's responsibility to establish appropriate health and safety practices and to ensure compliance with any legal regulations.

For the purposes of this standard, a liquid-applied waterproofing product is a single or multi-component waterproofing material applied in a uniform layer under the ceramic coating. The polymer modified cement based liquid applied waterproof product is a mixture of hydraulic binders, aggregates and organic additives that only need to be mixed with water or liquid additive just before use. If the reaction resin is a liquid-applied waterproof product, it is a mixture of one or more components of synthetic resin, mineral fillers and organic additives in which hardening occurs by chemical reaction.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for liquid-applied waterproof products for use under ceramic tiles bonded with adhesives within the scope of EN 14891 standard, with its trained and expert staff and advanced technological equipment. .
