Yield
Approx. 0.018 m3 (0.65 ft3) of fresh mortar per 30 kg (66 lb) bag
MIXING
Small batch
Important: In order to avoid segregation issues, always mix the total content of one bag. If less than a 30 kg (66 lb) of King® MasonMix 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water – the total contents of the bag in a clean container, take the required amount, and then add water to the amount withdrawn from the mixture.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 batch
Always mix the entire contents of the bag. Mix the King® MasonMix with a maximum of 5 L (1.3 US gal) of water per 30 kg (66 lb) bag in a clean mortar mixer. Pour 4.5 L (1.2 US gal) of water into the mixer and add 30 kg (66 lb) of King® MasonMix. Mix for 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.
APPLICATION
The application of the mortar must comply with the requirements of Sections 6 and 7 of CSA-A371-14.
CLEAN UP
In order to avoid the use of chemicals, it is always recommended to remove as much mortar splashes or stains as possible before the material hardens. Use water, a piece of burlap or wood. If the use of cleaning products is necessary, be sure to contact the manufacturer of the product to validate the compatibility and the procedure to follow. It is important to mention to the manufacturer that it is a hydrated lime-based mortar with the addition of iron and titanium oxides pigments when coloured.
Regardless of the technique or product selected, it is essential to preserve the integrity of the mortar.
Be sure to clean a test area before proceeding with the work.
Clean all tools and equipment after use with water. Once hardened, the product can only be removed mechanically.
