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

A special cement used in place of Portland Cement in cement: sand screeds for producing a rapid setting and drying floor screed that can be used as a bonded screed, an unbonded floor screed laid onto a membrane, or a floating screed laid onto compressive quilt or insulation material. It will be dry after 24 hours at 20°C to receive floor finishes, regardless of thickness.

Features and benefits:

• 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 A 55.
• 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.

Screed thickness:

The following thicknesses are recommended for screeds using ARDEX A 35:

• Bonded screeds: Minimum 15 mm (design thickness up to 40 mm).
• Unbonded screeds: Minimum 50 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.

Mix proportions:

• Heavy duty: A 1:4 mix is recommended where a very heavy duty floor is required.
• Standard: A 1:5 mix is recommended for all normal screeding situations.
