SAKRETE mason-craft is a pre-blended, pre-packaged,
Type O Mortar, specifically designed for use in repointing
and non-load-bearing wall applications. This mortar is a
blend of Portland cement, Type S hydrated lime, masonry
sand and other carefully selected components. SAKRETE
mason-craft conforms to ASTM C 270 for Type O Mortar,
with the addition of water. It is grey in colour, but can also be
blended with a variety of colouring agents.
FEATURES & BENEFITS
• High bond strength
• Breathability allows mortar to shed water
• Superior workability
• Self-healing capabilities for small movements or cracks
in masonry applications
• Pre-blended, ensuring consistency from the first batch
to the last
• All KING products are manufactured using
ISO 9001:2015 Certified Processes
USES
• Repointing
• Indoors or outdoors, for any other masonry application
where low strength and superior workability is required
READ ALL DIRECTIONS BEFORE STARTING WORK.
ATTENTION: WEAR GLOVES, SAFETY GLASSES AND
PROTECTIVE CLOTHING!
PROCEDURES
Mixing: For best results, add a maximum of 145 mL (5.0 oz)
of clean water per 1 KG (2.2 lb) of SAKRETE mason-craft,
into the mixer. Gradually add SAKRETE mason-craft to
water and mix with either a paddle-mixer or drill-mixer.
Operate until the mix is heavy-bodied enough to retain
its shape when fashioned, by hand, into a ball. Wait
approximately 30 minutes before the application. It is
important to mix the entire contents of the pail.
Placing: Clean the area to be repaired, removing all
loose material, at a thickness corresponding to 2 times the
thickness of the joint. Moisten the area to be repaired with
potable water, leaving the old masonry unit saturated but
free of standing water (SSD). Place SAKRETE mason-craft
into the joint in successive layers, to a maximum depth of
6 mm (¼ inch). Compact well and let dry slightly before
adding additional layers. Tool the joints prior to the final settime, in order to optimize carbonation.
CURING
Curing is essential to optimize the physical properties of the
mortar. Curing is performed by using a wet-cure that must
start from the initial set of the mortar, and continue for a
period of 3 days.
TECHNICAL DATA
The following data is representative of typical values
achievable under laboratory conditions, according to
ASTM C 270 for Type O Mortar. Results in the field may
vary.
COMPRESSIVE STRENGTH
28 Day 2.4 MPa (350 psi)
OPTIMUM PERFORMANCE
• SAKRETE mason-craft should not be used where Type
N Mortar or Type S Mortar is specified
• For applications requiring conventional Type N Mortar,
please refer to SAKRETE Mortar Mix, Type N; for
applications requiring conventional Type S Mortar,
please refer to SAKRETE Mortar Mix, Type S
• The substrate and mortar temperature should be
between 5 °C (40 °F) and 38°C (100°F) and maintained
in this range for 72 hours after mortar application
• SAKRETE mason-craft should be moist-cured for a
period of 3 days
• Never use on-site admixtures to modify setting time,
workability, or any other properties of plastic or hardened
mortar
• Use only the recommended water content to achieve
the desired plastic and hardened mortar properties
YIELD
2 KG (4.4 lb) pail contains approximately 0.0012 m3
(0.04 ft3)
of fresh mortar, or enough to repoint approximately 3 linear
metres (10 ft).
