Restore the timeless beauty and structural integrity of your historic masonry with our PHL 3.5 Lime-Based Repointing Mortar. This premium concentrate, available in convenient quart and gallon sizes, is formulated with no Portland cement.
This mortar provides similar performance, breathability, and historic characteristics of NHL 3.5 moderately hydraulic lime mortars. By blending this concentrate with locally sourced sand, you can effortlessly create a historically accurate and durable mortar, ensuring a seamless and long-lasting repair for your cherished structures.
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). It is free of Portland cement, making it ideal for repairs on historic masonry originally built with lime mortar. Our 3.5 formulation is between the 2.0 and 5.0 mortar strengths. It is ideal for moderate weathering environments. Typically choose 2.0 for very soft and fragile masonry repairs and 5.0 for high-weathering-exposure environments.,
- 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 help match the original mortar color of your historic structure.
- 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 historic brick and stone masonry built with lime mortar
- Repairing cracks, gaps, and deteriorated mortar joints in older structures
- Matching historic mortar colors and textures
- Restoring the structural integrity and aesthetic appeal of heritage buildings
Why Choose PHL 3.5 Lime Mortar?
Unlike modern cement-based mortars, which can be too rigid and trap moisture, our PHL 3.5 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:
- Combine one part PHL 3.5 concentrate with 2.5 to 3 parts clean sand.
- Gradually add water until the desired consistency is achieved.
- 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.
Invest in the preservation of your historic masonry with our PHL 3.5 Lime Repointing Mortar. Order your quart or gallon concentrate today and experience the difference that quality, authenticity, and breathability can make.

Let customers speak for us
from 76 reviewsI bought from them a few different times, the product comes quick, high quality, definitely recommend
I bought 5 gallons of PHL 3.5 Lime Mortar to repair the old stone walls of my basement. I am about halfway done the job. I will soon order another 5 gallons because this product is perfect for the job.
Great product. My order was filled quickly. We had some mortor joints we repaired and the color samples were ordered were a great match.
Great products and fast shipping, provided exactly what I needed. Highly recommend!
I couldn’t get the Type O mortar locally and Pro Mason Supply got it to me fast
Got their type O for my 1940's house. Works great, amazing product. Their support staff was also very helpful at editing my order. Highly recommend
Great customer service. Emails were responded to in a timely manner, answering all questions in detail. Product was easy to work with and the job finished off beautifully
Ordered masonry stain to change the color of my stone grout. Love that I don't have to re-grout in order to get the look I'm going for. Keep up the good work!
Took me a year (due to pauses in the project) but I’m finally finished! Stripped thick white paint off of my fireplace and all the scrubbing and scraping left the brick with a grey wash. I used the burgundy stain and it’s like it was never painted!
Will need help with the proper dilution level of your stone gray color
Loved how this turned out. Before and after. I used the charcoal gray and added randomly. I LOVE the way it turned out!!!
Fantastic experience. Ordering is so easy, shipping is fast, and the plaster has been easy to use.
