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 one bag. If less than a 30 kg of King® MasonBond 400® is required, dry mix - without water – the total content of the bag in a clean container, take the required amount, and then add water to the amount withdrawn from the mixture.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 content of the bag. Mix the King® MasonBond 400® with a maximum of 4.5 L (1.2 US gal) of water per 30 kg (66 lb) of mortar in a clean mortar mixer. Pour 4.0 L (1.0 US gal) of water into the mixer and add 30 kg (66 lb) of King® MasonBond 400®. Mix for three (3) to five (5) minutes. 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
This product contains a polymer in powder form. Avoid contact with the surface of the elements to be installed.
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. Uses 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.
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.
