ARDEX A38 MIX is a blend incorporating ARDEX A38 cement and graded sands, and has been specially formulated to produce ultra-rapid drying floor screeds for internal and external locations.  With ‘RAPIDRY PLUS FORMULA’ Technology, an ARDEX A 38 MIX screed can be walked on just 3 hours after application and ceramic and natural stone tiles can be installed after just 4 hours irrespective of thickness, making it ideal for fast track tiling projects. Resilient floorcoverings such as carpet, vinyl and wood can be installed after 48 hours irrespective of thickness. ARDEX A38 MIX achieves rapid strengthening and will pass a BRE Screed (ISCR) Test after just 6 hours. After a day, it will also exceed the acceptable minimum compressive and tensile bending strengths attained by ordinary cement screeds after 28 days.

USE

ARDEX A38 MIX is used to produce bonded, unbonded and floating screeds for internal and external locations, including wet areas such as swimming pools. It can also be used for large repairs to existing cement/sand screeds. It is ideal for situations where early foot traffic and rapid hardening is required.
