Application steps

MIXING

Pour the required quantity of water into a suitable mixing vessel. Slowly add the powder to the water whilst continuously mixing. Mechanical mixing is recommended. Suitable mixers include a slow speed high torque drill with a Mortar Stirrer or a forced action mixer such as Creteangle or Mixal. Mixing should be continued to form a mortar of consistency suitable for ramming into place.

 

APPLICATION

Place Parex Bedding Mortar SF firmly into the prepared gap. Use a suitable ramming tool to ensure complete filling of the gap and compaction of the mortar. Allow the mortar to stiffen then finish the exposed surface with a dampened steel trowel.

CURING TREATMENT

Curing of exposed surfaces should be undertaken in accordance with good concrete practice. Suitable methods of curing include water spray, polythene sheeting and spray applied concrete curing membrane such as Sikafloor® ProSeal W.

CLEANING OF TOOLS

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