Ardex - Arditex CL Powder & Latex (24.5kg) Latex Levelling and Smoothing Compound

ARDITEX CL is a latex levelling and smoothing compound with excellent flow and application properties. ARDITEX CL receives foot traffic after as little as 2 hours and most floorcoverings can be applied 12 hours after application. 

For smoothing and levelling most common internal subfloors such as concrete, cement/ sand and Gypsum (anhydrite) screeds. ARDITEX CL can be laid from a feathered edge to 10mm in a single application, or up to 30mm by incorporating ARDEX Coarse Aggregate.

Technical Information:

  • Appearance: ARDITEX CL: Polyethylene Lined Paper Sack 20kg; ARDITEX CL liquid is in a white polyethylene container 4.5kg
  • Bulk density of fresh mortar approx. 1.9Kg/litre
  • Compressive Strength Greater than 20N/mm² at 28 days
  • Tensile Strength Flexural Strength Greater than 7N/mm² at 28 days


Approximately 5m² per unit when applied as a typical smoothing application of between 2mm – 3mm. Note: Coverage rates will depend on the condition and absorbency of the subfloor


Pour the mixed material onto the prepared and primed subfloor. Spread with a trowel or suitable applicator to the required thickness in one operation. Apply at temperatures above 5°C and rising. The use of a spiked roller will improve the surface finish and performance of the ARDITEX CL mortar while it is still wet and workable.

Application Over Underfloor Heating - The cement/sand screed, concrete or calcium sulphate subfloor should be installed in accordance with BS 8204 Part 1. The under floor heating system should be commissioned in accordance with the manufacturer’s instructions and in accordance with the guidance given in BS 8204 Part 1. Once thermally cycled and commissioned, the underfloor heating should be turned down to 15°C before the application of the ARDITEX CL and the final floor covering. After 48 hours the under floor heating system should be gradually re-commissioned, in accordance with BS 8204 Part 1 and BS 8203 to avoid rapid thermal change and local variations in temperature.

Drying and Hardening:

Under good conditions a 3mm layer of ARDITEX CL is walkable after as little as 2 hours, and thin applications are ready to receive most floorcoverings after only 12 hours at 20°C. Setting, hardening and drying times will be extended at lower temperatures, and shortened at higher temperatures/humidity levels. Thicker applications will require longer to dry. The optimum site conditions required in BS 8203: 2001 for flooring installations is a minimum of 18°C and a maximum of 27°C and should remain constant before, during and after application of flooring products.


ARDITEX CL can be applied from a feathered edge up to 10mm in one application. To fully utilise its free flowing properties the product should be applied from 2mm. A minimum application of 3mm should be applied on an impervious subfloor where the floorcovering adhesive requires an absorbent layer. NOTE:  For thicknesses greater than 10mm, and up to a maximum of 30mm, incorporate up to an equal volume of ARDEX Coarse Aggregate.


ARDITEX CL contains more than 3% Portland cement and, therefore, in line with current legislation, is classified as irritating to eyes and skin. For this reason the following precautions should be observed: Avoid contact with skin and eyes; in case of contact with the eyes, rinse immediately with plenty of water and seek medical advice; wear suitable gloves and keep the product out of the reach of children. Avoid the generation of airborne dust during mixing. 

Storage and Shelf Life:

ARDITEX CL powder has a storage life of not less than 12 months if stored in dry conditions. ARDITEX CL latex has a storage life of 6 months in a sealed container if stored in frost free conditions, out of direct sunlight.
