can be covered with tiles and slabs early on
for indoor and outdoor use
Can be heated after 3 days according to aRdT
Areas of application:
ASO-EZ4 is a fiber-reinforced special cement for producing water-repellent, low-shrinkage cement screeds
and mortars with early readiness for covering. Screeds and mortars made with ASO-EZ4 offer water-repellent properties
Properties provide increased protection against frost damage and efflorescence. As a water-repellent, faster-hardening
Mortar bed when laying natural stones, tiles and slabs in outdoor and wet areas such as balconies, terraces, loggias,
Stairs, swimming pools, wet rooms, washrooms and water tanks.
A screed made with ASO-EZ4 is suitable as a composite rapid screed, floating rapid screed
Insulation or separating layer and heated screed, which is suitable as a wear layer or substrate for tiles, slabs and natural stone.
The general guidelines for cement screeds according to din 18560 and. apply to the execution
din 18353. The subsurface must correspond to the load-carrying capacity according to din 1991-1-1.
Furthermore, the ASO-EZ4 binder can be used to produce drainage mortars which, thanks to their porous,
A structure rich in cavities can drain away water. At the same time, the ASO-EZ4 drains mortar to a certain extent
its hydrophobic setting does not absorb any moisture and thus prevents capillarity.
In areas exposed to moisture, such as swimming pools, swimming pool surrounds and public showers or in the
Water impact class W1-I to W3-I according to din 18534, dindin 18535 is
a screed made with ASO-EZ4 must be sealed with a suitable composite seal.
ASO-EZ4 is a special cement without trace components. Some regulations, such as VOB din 18332,
DNV information sheets from the German Natural Stone Association, BIV information sheets from the Federal Association of German Stonemasons, ZDBM information sheets published by the German trade association
Tiling trade[1*], describe the use of mortars with a high level for outdoor/natural stone applications
route share. ASO-EZ4 uses a more advanced technology that, due to its special properties, has significantly lower “lime efflorescence” than trass mortar.
For screeds, laying and drainage mortars made from ASO-EZ4
It is therefore a special design. We therefore recommend that this be agreed contractually!
