King® HLM-500 C Series

Natural hydraulic lime-based masonry mortar with coarse sand for laying and repointing applications

King® HLM-500 C Series is a premixed, factory-bagged mortar made from 100 % natural binders and specially designed to be used when laying masonry units in historic preservation or new construction projects. This product is formulated with natural hydraulic lime, natural Type S hydrated lime, masonry sand containing particles variant from 0 mm to 5 mm (0 in to 0.2 in) (coarser than usual masonry sand), and an air-entraining admixture.

  • Factory calibrated mix
  • Formulated without cement
  • Formula similar to historic mortars
  • Excellent water vapour transmission properties
  • Ideal for joints larger than 10 mm (0.4 in)
  • Better resistance to freeze-thaw cycles than hydrated lime lime
  • Better resistance to de-icing salts than hydrated lime lime

Application steps

SURFACE PREPARATION

Repointing

Prepare the surface to be repaired in order to remove loose particles and faulty mortar on a thickness corresponding at least to twice the thickness of the joint to be repaired or up to obtaining a healthy mortar. Moisten the area to be repaired without leaving standing water in the cavities to be filled.

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® HLM-500 C Series 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water – the total content of the bag in a clean container, take the required amount, and then add water to the amount withdrawn from the mixture.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 batch for Laying Masonry Units

Always mix the entire content of the bag. Mix the King® HLM-500 C Series with a maximum of 5.5 L (1.45 US gal) of water per 30 kg (66 lb) bag in a clean mortar mixer. Pour 5 L (1.3 US gal) of water into the mixer and add 30 kg (66 lb) of King® HLM-500 C Series. 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.

   

Large batch for Repointing Application

Always mix the entire content of the bag. Mix the King® HLM-500 C Series with a maximum of 4.4 L (1.16 US gal) of water per 30 kg (66 lb) bag in a clean mortar mixer. Pour 3.9 L (1.03 US gal) of water into the mixer and add 30 kg (66 lb) of King® HLM-500 C Series. 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. Once well mixed, the consistency of the mortar should be firm enough to allow you to shape a ball with your hands. 

APPLICATION

The application of the mortar must comply with the requirements of Section 6 of CSA-A371-14.

CURING TREATMENT

Curing is essential for optimizing the physical properties of the mortar. Curing is carried out using a moist cure process which must begin as soon as the initial setting of the mortar and for a period of 3 to 7 days. To learn more about the moist cure, refer to the guide: How to perform a moist cure for masonry, published by Sika Canada and available on the company’s website.

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 hydraulic 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.
