Description

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.
