The addition of E 25 Mortar Admixture to ARDEX sub-floor smoothing compounds is recommended where high abrasion or point load resistance is required, when used as a temporary wearing surface, where a floor paint or paint thickness coating is to be subsequently applied as a finish (check compatibility, suitability, and carry out a trial application before proceeding) or where the floor has underfloor heating. In the latter case, the heating must be turned off for 48 hours before screeding, left off for a further 48 hours afterwards and gradually brought up to temperature.
