Application

Used to produce bonded, unbonded and floating screeds for internal locations. It can also be used for large repairs to existing cement/sand screeds. It is ideal for situations where early foot traffic and rapid hardening is required.

Description

Rapid drying pre-blended screeding and screed repair mortar, containing one part ARDEX A 35 quick drying cement and four parts, by weight, of screeding sand, requiring only the addition of water.


Features and benefits:

  • It's pre-blended so just add water.
  • Can be used to produce bonded, unbonded or floating screeds and will be dry after 24 hours at 20°C to receive floor finishes, regardless of thickness.
  • Pre-blended with graded sand for convenience - just add water.
  • Walkable in three hours.
  • Receives ceramic and natural stone tiles directly after 24 hours.
  • Install carpet, wood and vinyl floorcoverings after 24 hours, or just four hours for carpet and vinyl when smoothed with ARDEX A55.
  • Passes BRE Screed (ISCR) Testing after six hours.
  • After just one day, achieves the acceptable minimum compressive and tensile bending strengths attained by an ordinary cement, screed after 28 days.
  • Can be used with underfloor heating systems.
  • Weight of fresh mortar: Approximately 2 kg/L.
  • Walkability 20°C: Approximately three hours.
  • Compressive Strength (DIN 1164): After one day: 25.0 N/mm², After 3 days: 32.0 N/mm², After 28 days: 40.0 N/mm².
  • Tensile Bending Strength (DIN 1164): After one day: 5.0 N/mm², After three days: 6.0 N/mm², After 28 days: 7.0 N/mm².


Thickness:

When used as a repair mortar ARDEX A 35 MIX can be applied to the full thickness of the existing screed. When applied as a new screed, application at the following thicknesses is recommended:

  • Bonded screeds: Minimum 15 mm, (design thickness up to 40 mm).
  • Unbonded screeds: Minimum 40 mm.
  • Floating screeds: Minimum 75 mm (Minimum 65 mm in lightly loaded (domestic) locations).
  • Screed repairs: Can be applied to the full thickness of the existing cement/sand screed.
