Application

ARDEX A 29 is used to produce bonded, unbonded and floating screeds in internal or external locations. A 1:7 mix is suitable for most normal screeding situations. An ARDEX A 29 Screed passes the BRE Screed (ISCR) after 24 hours (tested on 50 mm unbonded at 20°C).

Description

Cement for screeds that has been developed to perform in real-site conditions, and combines excellent workability, speed and performance. The Rapid Hardening formula allows it to be walkable from just 8 hours, and tiled over in as little as 24 hours, while resilient floor finishes can be installed in just 7 days compared to over 30 with standard sand and cement screeds.


The working time of the mixed screed offers a large 90 minutes at 20°C, meaning the flooring contractors can mix and apply more screed at once with plenty of time for compacting and levelling, giving the perfect subfloor.


A very economical 1:7 mix (cement:sand) is suitable for most normal screeding situations, and can be applied at the conventional thicknesses for normal cement/sand screeds:


Minimum 20 mm at 1:5 ratio and minimum 25 mm at 1:7 ratio, (design thickness up to 40 mm) for bonded screeds.


Minimum 50 mm for unbonded screeds.


Minimum 75 mm for floating screeds. 65 mm in lightly loaded (domestic) locations.


Features and benefits:

  • 90-minute working time (at 20°C).
  • Walkable after eight hours (at 20°C).
  • Install ceramic tiles after 24 hours and natural stone after seven days.
  • Install resilient and wood floor finishes after seven days.
  • Apply as a bonded, unbonded or floating screed.
  • BRE Screed (ISCR) Test: Pass in 24 hours.
  • Rapid hardening.
