Ultra Rapid Drying Cement for Internal Screeds can be walked on in as little as 3 hours and receive resilient floor coverings in as little 24.
ARDEX A 35 is a special cement used in place of Portland Cement in cement:sand screeds for producing a rapid setting and drying floor screed that can be used as a bonded screed, an unbonded floor screed laid onto a membrane, or a floating screed laid onto compressive quilt or insulation material. It will be dry after 24 hours at 20°C to receive floor finishes, regardless of thickness.
The following thicknesses are recommended for screeds using ARDEX A 35:
Walkable in 3 hours; Receives ceramic and natural stone tiles directly after 24 hours; Install carpet, wood and vinyl floorcoverings after 24 hours, or just, 4 hours for carpet and vinyl when smoothed with ARDEX A 55; 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; For bonded, unbonded and floating screeds; Can be used with underfloor heating systems; Can be pumped for fast application
