scope:

This document applies to all liquid-applied water impermeable products, based on polymer modified cementitious mortars, dispersions and reaction resin coatings, used beneath ceramic tiling, for external tile installations on walls and floors and in swimming pools.

This document specifies the test methods and the requirements for the non-harmonized characteristic and the designation and marking of liquid-applied water impermeable products beneath ceramic tiling.

This document does not contain recommendations for the design and installation of ceramic tiles and grouts in combination with water impermeable products.

NOTE Liquid-applied water impermeable products are also used beneath other types of tiles (natural and agglomerated stones, etc.), where they do not adversely affect these materials.
