Ardex A70 GYPFLO Calcium Sulphate Screed (see Options)

DESCRIPTION:
ARDEX A 70 GYPFLO is a quick drying 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. 

USE:
ARDEX A 70 is used to produce unbonded and floating screeds for internal locations. It can also be used for repairs to existing calcium sulphate screeds. It is ideal for situations where early foot traffic and rapid hardening is required. ARDEX A 70 is suitable for use over underfloor heating systems. ARDEX A 70 must only be used on floors with a functioning damp proof system. ARDEX A 70 is not suitable for use in locations with prolonged exposure to moisture. 

THICKNESS:

Floating screeds -35mm domestic / 45mm commercial

Unbonded screeds 30mm domestic / 40mm commercial

Note: The minimum thickness of cover over underfloor heating elements (e.g. Pipes) is 25mm.

Unbonded Screeds:
For unbonded screeds, ensure that the concrete slab surface is reasonably true and flat prior to applying a proprietary damp proof/slip membrane.
