  • USDA/FDA/LEED acceptable

  • Should not be used in active or moving joints unless a relief joint is formed or saw cut

  • For deep repairs at warm temperatures, install in maximum 1” layers to avoid shrinkage due to exotherm

  • Surface preparation may be accomplished by grinding, sawing, chipping, sandblasting, etc. Prevent featheredging by creating a vertical edge (1/2” minimum, 3/4” preferred) at outer point of defect to be repaired. Mix with Jiffy mixer @ slow speed, install immediately, spread with trowel (use Xylene on trowel if it creates drag)

  • Promptly install mortar into defect, spread evenly using clean steel trowel. Finish installing each unit before mixing the next. Trowel mortar to desired density and finish texture. If mortar starts to stiffen and creates trowel drag, wipe trowel with solvent such as denatured alcohol, toulene, xylene or MEK. The final material density and appearance will reflect trowel pressure and intensity
