King® Block
Masonry mortar for laying applications
King® Block is a premixed, factory-bagged type S mortar specially designed for laying bricks, natural stone, concrete blocks and other masonry products where higher compressive strength is required. King® Block is formulated with cementitious materials, an air-entraining admixture and masonry sand with controlled grain size.

Yield
Approx. 0.018 m3 (0.65 ft3) of fresh mortar per 30 kg (66 lb) bag
MIXING
Small quantity
Important: In order to avoid segregation issues, always mix the total content of a bag. If less than a 30 kg (66 lb) of King® Block is required, dry mix - without water – the total contents of the bag in a clean container, take the required amount, and then add water to the amount withdrawn from the mixture.
Large quantity
Always mix the entire contents of the bag. Mix the King® Block with a maximum 4.5 L (1.2 US gal) of water per 30 kg (66 lb) bag in a clean mortar mixer. Pour 4 L (1 US gal) of water into the mixer and add 30 kg (66 lb) of King® Block. Mix for three (3) to five (5) minutes, or five (5) to ten (10) minutes when using a coloured mortar or when a colourant is added at the job site. Allow the mortar to stand for a short period of time. Using the remaining water, adjust the mortar to obtain the desired consistency.
Once the desired consistency is achieved, it is not recommended to add water to the coloured mortars in order to compensate for water loss caused by evaporation. Adding water may affect the final colour of the product.
APPLICATION
The application of the mortar must comply with the requirements of Sections 6 and 7 of CSA-A371-14.
