ARDEX A 35 produces ultra-rapid drying floor screeds which can be walked on after just 3 hours and floorcoverings installed in as little as 4 hours, regardless of thickness. Use ARDEX A 35 for bonded, unbonded and floating screeds in internal locations.

Features and benefits:

  • Walk on after 3 hours.
  • Receives ceramic and natural stone tiles directly after only 24 hours.
  • Install carpet, wood and vinyl floorcoverings after 24 hours, or just 4 hours for carpet and vinyl when smoothed with ARDEX A 55.
  • Passes BRE Screed (ISCR) Testing after 6 hours.
  • After just one day, achieves the acceptable minimum compressive and tensile bending strengths attained by an ordinary cement screed after 28 days.
  • For bonded screeds apply at 15 to 40 mm.
  • For unbonded screeds apply at 50 mm +.
  • For floating screeds apply at 75 mm + or 65 mm in lightly loaded/domestic locations.
