MIXING
Parex Dry Pack C can be mixed with a low speed (<500 rpm) hand drill mixer or for machine application, using a force action mixer 2 to 3 bags or more at once depending the type and size of mixer.
Pour the recommended water in a suitable mixing container. While stirring slowly, add the powder to the water and mix thoroughly until the mortar has formed a consistency suitable for ramming in to place.
APPLICATION
Place the Parex Dry Pack C mortar firmly into the prepared gap in layers. Use a suitable ramming tool to ensure complete filling of the gap and compaction of the mortar. Repeat this operation until the void is completely filled and compacted. Allow the mortar to stiffen then finish the exposed surface with a dampened steel trowel.
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.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use.
Hardened/cured material can only be mechanically removed.
