MIXING

Parex Rapid Mortar should be  mixed in quantities that can be used during the workable time of the mortar.
The mixing proportions are:
Rapid Mortar powder 3 parts by volume
Water 1 part by volume
Pour the required volume of clean water into a suitable mixing vessel. Slowly add the powder to the water whilst continuously mixing using a slow speed, high torque drill with mortar stirrer until the required consistency is obtained. Once mixed use immediately to avoid wastage.

 

APPLICATION

Apply Parex Rapid Mortar firmly onto the repair area. It may be necessary to use a gloved hand to compact the mortar behind steel and into narrow corners and edges. Surface finish the applied mortar with a damp steel trowel. Application thickness should be between 5 and 25mm. Thicker sections can be built up after the material has hardened sufficiently if a scored surface is left on the preceding layer.

CURING TREATMENT

Protect the fresh mortar immediately from premature drying for a minimum of 3 days using an appropriate curing method e.g. curing compound, moist geotextile membrane, polythene sheet etc.
Curing compounds shall not be used when they adversely affect subsequently applied products and systems.
Reference shall also be made to BS EN1504-10 for specific requirements.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use.
Hardened/cured material can only be mechanically removed.
