ARDEX K 71 – Rapid-Drying Industrial Topping & Wearing Surface
ARDEX K 71 is a cement-based self-levelling compound designed to resurface concrete floors, delivering a hard, smooth, and flat finish. Powered by the ARDEX ‘Rapidry Formula,’ it binds water chemically for rapid drying and high strength. Apply it via pump or trowel from 3-30mm neat, or up to 50mm with aggregate, over concrete or ARDEX SD-T Base Mix.
With special cements and admixtures, ARDEX K 71 withstands heavy wheeled traffic and abrasion. It’s walkable in 2-3 hours and ready for coatings in 24 hours (thickness-dependent), making it perfect for fast-track projects in warehouses, factories, and commercial spaces.
Flexible at 3-50mm thicknesses, this industrial-grade compound suits areas needing durability and aesthetics, from workshops to showrooms.
Key Benefits:
- Strong & Durable – Resists heavy traffic and abrasion for industrial use.
- Easy to Apply – 3-50mm application over concrete, pumpable or trowelable.
- Versatile – Works with resin coatings, tiles, and natural stone.
- Fast Drying – Walkable in 2 hours, coatings in 24 hours.
- Self-Levelling – Smooth, flat finish for aesthetics and function.
- Low Shrinkage – Minimizes cracking risks.
- Pumpable – Efficient for large areas.
- Underfloor Heating Ready – Modern flooring compatible.
- Fire Rating: A1 – Top safety standard.
Coverage: Approx. 4.7m² at 3mm per 25kg bag (varies with aggregate use—see datasheet).
Compare to BAL Level Max: ARDEX K 71 offers superior strength, rapid drying, and industrial-grade performance for demanding projects.
