SAKRETE mason-craft
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.
- 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
Usage
- Repointing
- Indoors or outdoors, for any other masonry application where low strength and superior workability is required

FAQ
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.
Use only the recommended water content to achieve the desired plastic and hardened mortar properties.
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.
300 mL (10.1 oz) tube fills a space approximately 6 mm (1/4 in) x 13 mm (1/2 in) x 3.6 m (12 ft).
SAKRETE mason-craft should not be used where Type N Mortar or Type S Mortar is specified
Place SAKRETE mason-craft into the joint in successive layers, to a maximum depth of 6 mm (¼ in).
SAKRETE mason-craft should be moist-cured for a period of 3 days.
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.
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 in). Compact well and let dry slightly before adding additional layers. Tool the joints prior to the final set time, to optimize carbonation.
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.
Never use on-site admixtures to modify setting time, workability, or any other properties of plastic or hardened mortar.
