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
Unit Size Available: 25kg
Coverage: Approximately 3.2m2 at 25mm thick per 25kg unit using the 1:5 mix
