This European Standard 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 European Standard gives the terminology concerning the products and specifies the test methods
and the values of performance requirements for liquid-applied water impermeable products associated
with tile adhesives.
This European Standard specifies the assessment and verification of constancy of performance, and the
classification and marking of liquid-applied water impermeable products beneath ceramic tiling.
This European Standard 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 may also be used beneath other types of tiles (natural and
agglomerated stones, etc.), where they do not adversely affect these materials.
