Ardex A35 Rapid Drying Cement
Rapid Setting and Ultra Rapid Drying Cement for Internal Floor Screeds
ARDEX A 35
Walkable in 3 hours
Receives floorcoverings after 24 hours, regardless of thickness
Passes BRE Screed Test after 6 hours
Information ARDEX A 35
Traditional sand/cement screeds can take months to dry, but an ARDEX A 35 screed can receive floorcoverings after only 24 hours, regardless of thickness. After only 1 day the compressive strength and tensile bending strength of an ARDEX A 35 screed exceeds the acceptable minimum attained by an ordinary cement screed after 28 days. ARDEX A 35 can be used to produce a bonded screed, unbonded floor screed laid onto a membrane, or floating floor screed laid onto a compressive quilt/insulating material.
- Walk on after 3 hours
- Receives floorcoverings, including ceramic tiles, after 24 hours regardless of thickness
- Receives resilient and textile floorcoverings after 4 hours when smoothed with ARDEX A 55
- Test with a BRE Screed Tester after only 6 hours
- Can be used with underfloor heating systems
