SURFACE PREPARATION :

Remove all impurities, dirt, grease, other bond inhibiting materials from surface. Preparation work should be done using manual or pneumatic cutting techniques. Dampen surface to be repaired with clean water.

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 15 minutes.

APPLICATION & FINISHING :

Mortar must be scrubbed into substrate, filling all pores and voids. Use a steel trowel. Force material against edge of repair, working toward center. When the mortar is the consistency of dry sand screed to desired finish.

CURING :

Curing is not necessary.

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.
