Key Features:

• Authentic PHL 3.5 Formulation: Our PHL 3.5 mortar is a pozzolanic lime mortar, a historically accurate blend of high-calcium lime and reactive clays (pozzolan).

• Versatile Quart & Gallon Concentrates: Choose the size that suits your project needs, with each container yielding approximately 4 times its volume in ready-to-use mortar when combined with local sand.

• Breathable for Optimal Moisture Management: The lime-rich formulation allows your masonry to "breathe," preventing moisture buildup and promoting long-term durability.

• Five Classic Colors: Select from white, gray, light buff, dark buff, or dark red to seamlessly match the original mortar color of your historic structure.
