Installation: Surfaces to receive Mason Mix should be clean and free of dirt, loose debris, grease, oil, etc., for the best possible bond.


  • For each 80lb. bag add 9pt. of fresh water to mixer
  • Turn the mixer on and begin adding bags of Mason Mix

If the material becomes too difficult to mix, add additional water until a workable mix of trowelable consistency is obtained.
Note: Final water content should be 9-14pt. for each 80lb. bag


  • Apply a full bed of mortar onto the base, approximately 1/2"-3/4" thick
  • Push downward into the mortar bed and sideways against the previously laid block witha slight twisting motion

Tool the mortar joints when they become thumbprint hard. This will make the mortar joint watertight and provide neat appearance.
