ARDEX K 301 is a Fast Setting Resurfacing and Levelling Compound for Concrete. ARDEX K 301 is a grey powder consisting of special cements, graded aggregates and high quality synthetic resins.
When mixed with water, a fluid mortar is produced which sets after approximately 1 hour and can normally be walked on after 2-3 hours at 20°C. ARDEX K 301 can be applied from 2mm to 20mm in a single application. The set and hardened ARDEX K 301 is usually ready to receive light rubber wheeled traffic after 48 hours at 20°C.
