ARDEX A 70 GYPFLO is a quick drying, flowable Calcium Sulphate screed that is specially formulated to receive floorcoverings in as little as 14 days – twice as fast as standard Calcium Sulphate screeds. ARDEX A 70 GYPFLO is pre-blended and only requires the addition of water. ARDEX A 70 is used to produce unbonded and floating screeds for internal locations.
• Walkable in as little as 6 hours
• Ready to receive floorcoverings in as little as 14 days
• Pre-blended for consistency and convenience – just add water
• Pump or hand apply – ideal for areas with restricted access
• Excellent flow properties
• Low shrinkage minimises cracking and curling
• High early and final strength development (CA-C40-F7)
• Can be used with underfloor heating systems
COVERAGE
A 25kg bag of ARDEX A 70 will cover approximately
