SURFACE PREPARATION :

Joints to receive the mortar must be sound and free of all dust, dirt, grease and other bond inhibiting materials from surface. Preparation work should be done using manual or pneumatic cutting techniques without disturbing the stone or brick. Unsound mortar should be cut out to a depth of 1cm (½") – preferably 2 cm (¾").

MIXING :

The mixing ratio is approximately 5 parts powder to 1 part water. Use clean container. Pour water into mixing container. The mixing may be done by hand or using a slow speed drill (300-450 rpm) with a mixing paddle. The mortar should be the consistency of damp sand. Do not over water. Do not over-mix. Working time is approximately 2 hours.

APPLICATION & FINISHING :

Wet the cleaned joints just before applying the mortar, just enough to dampen the surface. Use appropriate pointing tools so that it matches the original joint profile. The mortar should be firmly pressed to form a packed joint without voids.

CURING :

Use mist spray of clean water periodically for 3 days after installation.

CLEAN UP :

Remove the mortar from tools and mixing equipment with water. Cured material can only be removed mechanically.

CAUTION :

Avoid eye-contact and prolonged contact with skin. May cause irritation to sensitive skin. In case of skin or eye contact, wash thoroughly with water. If eye contact, consult nearest doctor.
