PRODUCT DESCRIPTION
greencoreusa
®
Super High Yield Mortar is an ecologically friendly,
high performance blend of mortar cement, dried sand, and other
engineered ingredients. The greencoreusa® Super High Yield Mortar
meets ASTM C270, C1714, and ICC requirements for masonry
mortars when properly mixed in the field. The superior bond of the
greencoreusa® Super High Yield Mortar helps to reduce waste.
PRODUCT USE
greencoreusa
®
Super High Yield Mortar is recommended for interior
or exterior construction application, above and below grade, load
bearing and non-load bearing. greencoreusa® Mortars can be used
to lay block, brick, natural or manufactured stone, or as an
underlayment for tile, marble, and slate.
COLORS
greencoreusa
®
Super High Yield Mortar is available in gray and
additional colors by special order.
SIZES
65 lb (29.4 kg) bags
80 lb (36.2 kg) bags
YIELD
One 80 lb (36.2 kg) bag with no waste will lay up to 32
standard concrete blocks (8 in x 8 in x 16 in (200 mm x 200 mm x 400
mm) with 3/8 in (9.5 mm) mortar joints when applied to face shells
and head joints only. One 65 lb (29.4 kg) bag with no waste will lay
up to 26 standard concrete blocks (8 in x 8 in x 16 in (200 mm x 200
mm x 400 mm) with 3/8 in (9.5 mm) mortar joints when applied to face
shells and head joints only. Yield depends on added water, workers’
skill, and job site conditions, and therefore, cannot be guaranteed.

INSTALLATION
SURFACE PREPARATION
Surfaces to receive Super High Yield Mortar should be clean and
free of dirt, loose debris, grease, oil, etc., for the best possible
bond.
MIXING
Use clean water, approximately 10.5 pt (5 L) per 80 lb (36.2 kg)
bag or 9 pt (4.2 L) per 65 lb (29.4 kg) bag. Pour 3/4 of the water
into the mixer. With the mixer running, add bags of dry mortar
and mix thoroughly. At least five minutes of mixing time is
recommended. Add additional water in small amounts as
necessary to achieve optimum workable consistency. Caution:
Adding too much water will reduce strength. Let mix stand for 2
minutes to enable absorption of water and re-mix.
INSTALLATION
Apply a full bed of mortar onto the base, approximately 1/2 - 3/4
in (13 - 19 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
Loss of surface water occurs rapidly under conditions of high
temperature, low humidity, and wind. Lightly spray water as
needed. Protect from rain for 24 hours. In cold weather,
adequately cover and keep from freezing for a minimum of 24
hours.
RECOMMENDATIONS AND PRECAUTIONS
Always follow traditional industry best practices appropriate for
the application and weather conditions. See
www.greencoreusa.com for additional information.
Setting time may be adjusted by using cold water at high
temperatures or warm water at low temperatures.
Do not apply when air or substrate temperatures are below or
expected to fall below 40°F (4°C) within 48 hours of placement.
Do not use as a grout.
Water with a high mineral salt content can cause efflorescence.
Efflorescence occurs naturally and is beyond manufacturer’s
control.
