ARDEX Americas is pleased to announce that ARDEX K 521 Self-Leveling Concrete Topping with Aggregate Surface is now available. Like ARDEX K 520, launched earlier this year, ARDEX K 521 is a self-leveling topping used for fast track resurfacing, smoothing or leveling of various indoor concrete and certain non-porous surfaces.
- ARDEX K 521 can be installed from 3/8” up to 2”, walked on in 2-3 hours, and polishing can begin in as little as 24 hours.
- It is easy to install and typically requires less steps to polish when compared to other toppings.
- ARDEX K 521 has a distinctive “aggregate-exposed” surface when polished.
- It is an extremely durable wear surface with very high compressive strength, and increased scratch and dent resistance.
