Non-corrosive accelerating admixture

K-Set is a non-corrosive accelerating admixture that does not contain calcium chloride. This admixture speeds up the hydration of cement, leading to quicker setting times and significant early strength gains. K-Set enhances workability, helps prevent segregation, and is beneficial in the early stiffening of mortar and stucco mixes. Formulated as an aqueous solution of organic and inorganic compounds, K-Set generates rapid heat development in mortar, which is critical for preventing freezing at low temperatures soon after application. This product is V.O.C. compliant.

  • Accelerates Setting Times: Shortens setting times by one to three hours, crucial for efficient project timelines.
  • Freeze Protection: Accelerates early strength to help safeguard against freezing.
  • Enhanced Workability: Boosts production efficiency by improving mortar workability and reducing set times.
  • Strong Early Development: Generates high early strength, vital for structural integrity.
  • Corrosion Prevention: Ideal for applications where the corrosive effects of calcium chloride are a concern.
  • Environmentally Conscious: Fully compliant with environmental V.O.C. standards.

Tech Sheet
Safety Sheet


Incorporate K-Set into the water used for mixing mortars. It can also be added directly to the sand or the full mix but should never be mixed with dry cement or pre-mixed with other additives. The following dosages are recommended based on the type of cement and environmental conditions:

  • Portland Cement: 18 to 46 oz per 94 lb bag.
  • Masonry Cement: 10 to 25 oz per bag. The specific dosage should be fine-tuned based on the materials and conditions of each project.


  • 55 gallon drums
  • 5 gallon pails
  • 1 gallon jugs (sold in cases of 4)

Shelf Life

Store K-Set in its original sealed container to maintain a shelf life of 1 year from the date of manufacture. Keep the container free from water, dirt, and other contaminants.


K-Set adheres to ASTM C-494 and ASTM C-270 standards, qualifying it as a non-chloride masonry accelerator that meets industry standards.
