Ardex A 35 Ultra Rapid Drying Cement for Internal Screeds 25kg

ARDEX A 35 produces ultra-rapid drying floor screed 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.

• 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
• 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

USE
ARDEX A 35 is 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.

THICKNESS
ARDEX A 35 should be applied to the following thicknesses:

• Bonded screeds: 15mm - 40mm
• Unbonded screeds: 50mm+
• Floating screeds: 75mm+ or 65mm+ in lightly loaded/ domestic locations

When used for screed repairs, ARDEX A 35 can be applied to the full thickness of the existing cement/sand screed.

COVERAGE
Using a 1:4 mix, by weight material requirement is approximately 0.37kg of ARDEX A 35 per m2 per millimetre of screed thickness i.e. approximately 2.7m2 at 25mm thick or 4.5m2 at 15mm thick per bag.

Using a 1:5 mix, material requirement is approximately 0.31kg of ARDEX A 35 per m2 per millimetre of screed thickness i.e. approximately 3.2m2 at 25mm thick or 5.4m2 at 15mm thick per bag.

For slurry bonding, allow an extra 2 x 25kg ARDEX A 35 cement and 3 x 5kg of ARDEX P 51 bonding agent or 9 x 25kg ARDEX A 18 per 100m2.

Working time at 20°C: approx. 60 minutes

Walkability at 20°C: approx. 3 hours

MOISTURE TESTING: The Speedy Moisture Tester (Carbide Method) must be used to test moisture. Please consult ARDEX Technical Services for further advice.
