ARDEX K301 Exterior Self-Smoothing Levelling & Resurfacing Compound Grey 25kg – Pallet of 48

ARDEX K 301 is a fast-setting resurfacing and leveling compound designed specifically for concrete surfaces. Here are four key points about ARDEX K 301: Composition and Setting Time: This grey powder is made from a blend of special cements, graded aggregates, and high-quality synthetic resins. When mixed with water, it forms a fluid mortar that begins to set within approximately 1 hour. It can typically be walked on after 2-3 hours at 20°C. Application Thickness: ARDEX K 301 can be applied in thicknesses ranging from 2mm to 20mm in a single coat. This versatility allows it to cover a range of surface imperfections in one application. Traffic Tolerance: Once set and hardened, ARDEX K 301 can generally handle light rubber-wheeled traffic after 48 hours at 20°C. This makes it suitable for areas with regular foot and light vehicle use. Uses: Ideal for smoothing and leveling concrete surfaces such as balconies, patios, driveways, garages, and walkways, ARDEX K 301 is also effective for filling holes and resurfacing damaged floors. It is compatible with concrete or bonded cement/sand screeds with a compressive strength greater than 30 N/mm² and a pull-off strength greater than 1.5 N/mm². Additionally, it can be used to pre-smooth floors before applying a damp-proof membrane like ARDEX DPM 1C/1CR. This compound is highly practical for both new projects and repairs, ensuring a smooth, durable surface ready for various types of traffic and use. Coverage: One 25kg bag of ARDEX K 301 powder covers about 3.0 square meters at a thickness of 5mm. This is based on using approximately 1.6kg of ARDEX K 301 powder per square meter per millimeter of thickness. Storage and Shelf Life: Store ARDEX K 301 in its original, unopened packaging, off the ground, in a cool, dry place, and protect it from drafts. When stored correctly, it has a shelf life of 12 months from the date on the packaging.
