Coverage:
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.
Application:
Repairs – Apply the mortar with a trowel to holes, cracks, and 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, stair tread 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 the direct application of floor coverings. High aggregate content mixes may require a second application of ‘neat’ ARDEX ARDURAPID A45 or ARDEX FEATHER FINISH. Apply at temperatures above 5°C.
Precautions:
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.
