Product Description: Type O Lime Based Repointing Mortar


Restore the beauty and structural integrity of your historic masonry with our Type O Lime Based Repointing Mortar. This premium 1-gallon concentrate is specifically formulated for the meticulous restoration of "transition period" masonry, where traditional lime mortars were beginning to incorporate small amounts of cement. By mixing this concentrate with locally sourced sand, you can easily create the perfect mortar for your project, ensuring a seamless and historically accurate repair.

Key Features:

  • Authentic Transition Period Formula: Our Type O mortar replicates the composition of mortars used during the transition from pure lime to lime-cement blends, ensuring compatibility with your historic masonry.
  • Versatile 1-Gallon Concentrate: Each one gallon container yields approximately 4 gallons of ready-to-use mortar when combined with local sand, providing ample material for many smaller repointing projects.
  • Lime-Based for Breathability: The lime-rich formulation allows your masonry to "breathe," preventing moisture buildup and promoting long-term durability.
  • Five Classic Colors: Choose from white, gray, light buff, dark buff, or dark red to match the original mortar color of your structure. You can blend our mixes together or add additional cement-grade pigments to create custom colors.
  • Easy Mixing and Application: Simply combine the concentrate with sand and water according to the provided instructions for a smooth, workable mortar that is easy to apply.

Ideal Applications:

  • Repointing brick and stone masonry from the transition period (late 19th to early 20th century)
  • Repairing cracks, gaps, and deteriorated mortar joints
  • Matching historic mortar colors and textures
  • Restoring the structural integrity and aesthetic appeal of heritage buildings

Why Choose Type O Lime Mortar?

Unlike modern cement-based mortars, which can be too rigid and trap moisture, our Type O lime mortar allows your masonry to flex and breathe, preventing damage caused by freeze-thaw cycles and ensuring a longer lifespan for your restoration work. By using a historically accurate mortar, you preserve the authenticity of your building while ensuring its continued preservation for generations to come.

Mixing Instructions:

  1. Combine one part Type O concentrate with 2.5 to 3 parts clean, sharp sand.
  1. Gradually add water until the desired consistency is achieved.
  1. Mix thoroughly until the mortar is smooth and homogenous.

Safety Precautions:

  • Always wear appropriate safety gear, including gloves and eye protection, when handling mortar.
  • Follow the manufacturer's instructions and safety guidelines for proper mixing and application.
