Ardex A38 Rapid Hardening and Drying Cement is for Internal or External Locations.
Ardex A38 uses a Rapid Plus Formula. Able to totally bind water used for mixing within the mortar, ensures rapid drying and hardening properties.
The rapid drying time of Ardex A38 sees installation of floor coverings, such as ceramic or natural stone tile in 4 hours. Installation in just 48 hours for resilient and textile coverings, regardless of thickness!
Resilient floorcoverings such as carpet, vinyl and wood can be installed after 48 hours irrespective of thickness.
Ardex A38 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 is used to produce bonded, unbonded and floating screeds for internal and external locations
Can also be used in 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. THICKNESS Ardex A38 should be applied to the following thicknesses as recommended by BS 8204: Part 1 or BS 5385: Part 3: Bonded screeds: 15mm - 40mm.
Unbonded screeds: 50mm+. Floating screeds: 75mm+ or 65mm+ in lightly loaded/domestic locations. When used for screed repair
Ardex A38 can be applied to the full thickness of the existing cement/sand screed.
COVERAGE Using the recommended 1:5 mix, material requirement is approximately 0.31kg of ARDEX A 38 cement per m2 per millimetre of screed thickness i.e. approximately 3.2m2 at 25mm thick or 5.4m2 at 15mm thick per bag.
