Exterior self-levelling concrete resurfacing compound. 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.
Features:
- Flowable Cementitious Levelling and Repair Mortar – for the repair and levelling of rough or damaged concrete
- Suitable for internal and external applications onto concrete and bonded cement/sand screeds
- For smoothing and resurfacing paths, drives, parking areas, courtyards, etc.
- Fast setting – walkable after 2-3 hours
- Rapid hardening – can withstand light vehicular traffic after 48 hours
- Easy to mix and apply – can be pumped
- Apply from 2mm to 20mm thick in a single application
- Can be sealed, painted or used with suitable resin coatings
Uses:
ARDEX K 301 will smooth and level concrete surfaces such as balconies, patios, domestic driveways, garages, walkways and other concrete surfaces exposed to normal foot and rubber wheeled traffic.
ARDEX K 301 can also be used for filling holes and resurfacing damaged floors, such as concrete or a bonded cement/sand screed (>30N/mm2 compressive and 1.5N/mm2 pull off), as well as pre-smoothing concrete floors prior to the application of a suitable damp proof membrane.
NOTE: ARDEX K 301 is not recommended for heavy duty industrial floors, public highways or traffic with solid or metal wheels. ARDEX K 301 is suitable for permanently wet areas and may be used in swimming pools where it can be tiled onto directly.
ARDEX K 301 is not recommended for areas of intensive abrasive use in wet areas. Do not apply ARDEX K 301 over asphalt or tarmacadam surfaces. The hardened ARDEX K 301 should be protected from spillages and materials which damage concrete surfaces. If required, the dried ARDEX K 301 can receive suitable sealers, paints or coatings.
