Although it' s highly unlikely, the mortar might blow out from the filled holes violently if the following instructions have not been followed correctly:
  Using right type of STONE-TECH^® according to the worksite temperature.
  Too large hole diameter may result in blowout shoots.
  Too shallow holes may result in blowout shoots. Depth must be 4 times longer than its diameter
    or more.
  Lots of dry dust in holes will absorb water from mortar and result in blowout shoots.
  Cooling STONE-TECH^® powder, water, mixing tools before mixing while the temperature is higher
    than the requirements.
  Using enough water and mixing thoroughly to avoid lump formation for at least 2~3 minutes.
  Do not mix manually more than 10 kg (2 bags) for each lot.
  Pour the mixture into holes within 10 minutes after mixing.
  If the mortar becomes lightly stiff, add a little more water to achieve the right fluidity
  Do not overfill the holes.
  Do not plug filled holes with bars or similar tools.
  Dispose of non used mortar only after substantial dilution with water on an open surface.
