INSTALLATION
SURFACE PREPARATION
Surfaces to receive Mortar Mix should be 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 (4.3 L) of fresh water to mixer
• Turn the mixer on and begin adding bags of Mortar 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 - 6.6 L) for each 80
lb (36.3 kg) bag and 7 - 10 pt (3.3 - 4.7 L) for each 60 lb (27.2 kg)
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.
