Ardex - Ardurapid A45 (11kg) Rapid Drying and Hardening Internal Repair Mortar

ARDEX ARDURAPID A45 is a rapid drying and hardening, slump free mortar for internal repairs. The mixed mortar sets after 15 minutes and can be trafficked after just 90 minutes regardless of thickness at 20°C. 

ARDEX ARDURAPID A45 is ideal for:

  • Re-profiling, repairing and refacing internal concrete stairtreads and risers, cement and sand screeds and concrete floors
  • Filling and patching cracks in walls, ceilings and soffits.
  • Making good around pipework, door and window frames.
  • Forming ramps from a feather edge to normal screed thicknesses.
  • Forming coves. 

When using ARDEX ARDURAPID A45 as a wearing surface a suitable coating is required.

Technical Information:

  • Appearance: Polyethylene Lined Paper Sack
  • Bulk density of powder approx. 1.4kg/litre
  • Weight of fresh mortar approx. 1.9kg/litre
    *dependant on substrate, application thickness and temperature.


Depending on the flatness of the surface, an 11kg bag will cover approximately 7m2 at 1mm thick (7 litres of mortar). Note: Coverage rates will depend on the condition and absorbency of the subfloor.


Repairs - Apply the mortar with a trowel to holes, cracks, damaged and worn areas, ensuring that the mortar “wets” the surface by trowelling in firmly, leaving the repair proud. After about 15 minutes trim off excess and finish off with a wet trowel, sponge or sponge float to obtain a smooth surface. As soon as the ARDEX ARDURAPID A45 repair has hardened, the surface of the floor, stairtread etc., can be levelled, if necessary, with the appropriate ARDEX levelling and smoothing compound. 

Smoothing and Refacing - Apply the mixed mortar with a trowel to the required thickness. The material may be finished with a wet trowel after 15 to 20 minutes to provide a finish suitable for direct application of floorcoverings. High aggregate content mixes may require a second application of ‘neat’ ARDEX ARDURAPID A45 or ARDEX FEATHER FINISH. Apply at temperatures above 5°C.


ARDEX ARDURAPID A45 is considered non-hazardous in normal usage. The presence of cement in the product gives an alkaline mortar which may cause some local irritation if prolonged contact with the skin takes place. Care should be taken to avoid inhalation or ingestion of dust and prevent contact with the eyes.

Storage and Shelf Life:

ARDEX ARDURAPID A45 must be stored in unopened packaging, clear of the ground in cool dry conditions and be protected from excessive draught. If stored correctly, as detailed above, the shelf life of this product is 12 months from the date shown on the packaging.
