King® 2-1-9

Masonry mortar for laying applications

The King® 2-1-9 is a premixed, factory-bagged Type S mortar specially designed for laying bricks, natural stones, concrete blocks and other masonry products, when a higher compressive strength is required. King® 2-1-9 is formulated with Portland Cement, Type S hydrated lime, an air-entraining admixture, and masonry sand with controlled grain size.    

  • Factory calibrated mix
  • High compressive strength
  • Superior adhesion
  • Superior workability
  • Good resistance to freeze-thaw cycles
  • Self-healing property

Application steps

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® 2-1-9 is required, dry mix - without water – the total content of the bag in a clean mixing container, take the required amount, and then add water to the amount withdrawn from the mixture.

   

Large batch

Always mix the entire content of the bag. Mix the King® 2-1-9 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® 2-1-9. 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.

CLEANING

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.

Brick or Stone Concrete

Concrete brick units often have a low absorption rate. Therefore in order to reflect this characteristic, it is not uncommon for the mason to adjust the required amount of water.

Granite Stone Facing

Installation of any exterior facing is particularly important, since the facing is the first defence against water infiltration. One of the roles of mortar is to effectively manage rainwater flowing over the facing.

Concrete Blocks Indoor

The type of mortar to be used for installing concrete blocks indoors depends on the type of application. Since there will be no rainwater to manage, lime mortars are not necessary.

Exterior Chimney

The elements that make up an exterior chimney are subject to a high level of saturation. Furthermore, installation of any exterior facing is particularly important, since the facing is the first defence against water infiltration.

Concrete Block Foundation

Concrete block elements, which make up a buried foundation wall, are generally exposed to a high level of saturation. For this type of application, standard CSA A 179-14 recommends using a Type S Mortar, at a minimum.

Natural Stone Foundations

The natural stone elements that make up a buried foundation wall are generally exposed to a high level of saturation. For this type of application, standard CSA A 179-14 recommends using a Type S Mortar, at a minimum.

Parapet

Elements that compose an outdoor parapet are subject to a high level of saturation since the front, back and top are exposed to the elements.

Construction of a Retaining Wall

Since it takes less energy to manufacture lime than Portland Cement, it is always preferred from an environmental standpoint to use a lime mortar.

Retaining Walls

In addition to usually being exposed to de-icing salts, retaining walls, just like chimneys and parapets, are often exposed to elements such as wind and rain. Furthermore, they are exposed to a large number for freeze-thaw cycles without much protection.

Walls Built From 1975 to Today

Walls built between 1975 and today are generally constructed from a steel or wooden structure to which a masonry facade is attached. These walls are often built using a mortar containing masonry cement or a pure lime and Portland cement based mortar.

Repointing Stairs

Stairs are generally made from granite stone. Granite is a very dense material which makes it difficult to absorb water contained in fresh mortar. Because of this, the bond between mortar and masonry could be affected.
