Application steps

MIXING

Parex Dry Pack C can be mixed with a low speed (<500 rpm) hand drill mixer. For larger volumes (i.e. 2 to 3 bags, or more) mixed at once, a forced action mixer shall be used. The amount that can be satisfactorily mixed at a time will depend on the type and size of mixer used. 
Pour the recommended amount of water into a suitable mixing container. Whilst stirring slowly, gradually add the powder to the water and mix thoroughly until homogeneous and the mortar has formed a consistency suitable for ramming into 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 EQUIPMENT

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