Applications:
Preparatory Work
Surfaces to receive Blended Mason Mix should
be dry, clean and free of dirt, loose debris,
grease, oil, etc., for the best possible bond.
Mixing
• For each 80 lb. (36.3 Kg) bag, add 9 pt
(4.3L) of fresh water to the mixer
• Turn the mixer on and begin adding bags of
Blended 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 9-14
pt (4.3-6.6L) for each 80 lb. (36.3Kg) bag.
Installation
• Apply a full bed of mortar onto the base,
approximately 1/2”-3/4” (12.7-19.1 mm)
thick.
• Push downward into the mortar bed and
sideways against the previously laid block
with a slight twisting motion
• Tool the mortar joints when they become
thumbprint hard. This will make the mortar
joint watertight and provide a neat
appearance.
Curing:
Curing of masonry mortars is required only if
conditions are very hot, dry or windy. In such
cases, a gentle mist of water applied to the
surface will prevent premature drying and
improve the strength of the mortar.
NOTE: Variations in mix water amount, mixing
time, curing conditions and finishing will cause
color variations.
