Ardex Arditex NA Powder & Latex (24.5kg) Ultra Rapid Setting Latex Subfloor Levelling and Smoothing Compound

ARDITEX NA is a self-smoothing, protein-free, latex levelling compound with improved flow and excellent adhesion, flexibility and moisture resistance. These unique properties ensure that ARDITEX NA can be used with confidence over almost all subfloors without priming, including ceramic tiles, bitumen and flooring-grade plywood. Resilient floor coverings can be installed after just 4 hours and ceramic tiles in as little as 3 hours.

To level uneven internal subfloors to provide a smooth surface. ARDITEX NA can be applied on all common subfloors such as concrete and cement/sand screeds, prepared terrazzo, flooring grade asphalt, quarry tiles, internal steel floors, ARDEX Damp Proof Membranes, porcelain tiles, flooring grade plywood etc. It is ideal for use where low-odour products are required. ARDITEX NA can also be used to encapsulate under-tile heating cables/mats onto concrete/ screed/tile backing boards, prior to fixing ceramic floor tiles. ARDITEX NA can be laid from a feather edge up to at least 12mm in a single application or up to 30mm incorporating ARDEX Coarse Aggregate. NOTE: ARDITEX NA should not be used on top of the rubber, linoleum, cork or moisture-sensitive floor coverings.

Product Specifications & Key Features:

  • Appearance: ARDITEX NA: Polyethylene Lined Paper Sack 20kg; ARDITEX NA latex is in black polyethylene containers 4.85kg
  • Bulk density of powder approx. 1.3kg/litre
  • Initial Set (Vicat) approx. 1 hour
  • Final Set (Vicat) approx. 11/2 hours


Coverage is dependent upon the application thickness and texture of the substrate. A rough textured surface, or slightly thicker application, will decrease coverage, whereas a smooth substrate, or slightly thinner application, will improve coverage. Therefore the actual coverage achieved on-site may vary. For example, 5m² will be achieved per unit at approximately 3mm thick on a smooth surface. For other application thicknesses see the technical data section. When a unit is mixed with either an equal volume of 3mm to 8mm aggregate or ARDEX Coarse Aggregate (25kg) this will cover approximately 1m² at 20mm thick.

NOTE:  The excellent flow and wet edge time of ARDITEX NA means that, in practice, thinner applications are possible which can dramatically improve coverage.


The mixed material is poured onto the prepared floor surface and spread with a trowel to the required thickness in one operation. Apply at floor temperatures above 5°C. The use of a spiked roller will improve the surface and performance of the applied mortar whilst still wet.

Drying and Hardening:

At normal temperatures, the working time is approximately 20 minutes. ARDITEX NA can be walked on approximately 2 hours after application, depending on thickness and site conditions. A 3mm layer of ARDITEX NA is typically suitable to receive ceramic tiles in as little as 3 hours and most other floorcoverings after 4 hours under good conditions. The setting, hardening and drying times will be extended at lower temperatures and shortened at higher temperatures. Thicker applications will require a longer time to dry, however, even at thicknesses up to 10mm, floorcoverings can be installed after 24 hours.


The standard mix is suitable for applications from a feather edge up to 12mm, however for thicknesses above 8mm the incorporation of up to an equal volume of ARDEX Coarse Aggregate will prove economic.

Storage & Shelf Life

ARDITEX NA powder has a storage life of not less than 12 months if stored in dry conditions. ARDITEX NA latex has a storage life of 9 months in a sealed container if stored in frost-free conditions, out of direct sunlight.
