Overview:
Restore your weather-exposed masonry with our PHL 5.0 Lime Repointing Mortar.
This premium concentrate, available in convenient quart and gallon sizes, is formulated with no Portland cement to replicate the performance, breathability, and historic characteristics of NHL 5.0 eminently hydraulic lime mortars.
By blending this concentrate with locally sourced sand, you can effortlessly create a historically accurate and exceptionally durable mortar, ensuring a long-lasting repair for masonry exposed to harsh weather conditions.
Key Features:
- Authentic PHL 5.0 Formulation: Our PHL 5.0 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 eminently hydraulic lime mortar.
- 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.
- Enhanced Weather Resistance: The eminently hydraulic nature of PHL 5.0 provides superior resistance to weathering, making it ideal for exposed masonry like chimneys, parapets, and facades.
- 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 eminently hydraulic lime mortar
- Repairing cracks, gaps, and deteriorated mortar joints in exposed masonry
- Matching historic mortar colors and textures in challenging environments
- Restoring the structural integrity and aesthetic appeal of heritage buildings in harsh climates
Why Choose PHL 5.0 Lime Mortar?
Unlike modern cement-based mortars, which can be too rigid and trap moisture, our PHL 5.0 lime mortar offers the strength and durability of eminently hydraulic lime while still allowing your masonry to breathe. This makes it ideal for use in exposed locations where resistance to weathering is crucial. By using a historically accurate mortar with the appropriate hydraulic properties, you ensure the longevity and beauty of your restoration work, even in challenging conditions.
Important Note: PHL 5.0 is specifically designed for masonry exposed to high weathering conditions. For masonry in sheltered locations or requiring less strength, consider our PHL 2.0 or PHL 3.5 mortars.
Mixing Instructions:
- Combine one part PHL 5.0 concentrate with 2.5 to 3 parts clean masonry 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 exposed masonry with our PHL 5.0 Lime-Based Repointing Mortar. Order your quart or gallon concentrate today and experience the difference that quality, authenticity, and exceptional weather resistance can make.

Let customers speak for us
from 43 reviewsThe website was easy to order from and I really appreciate the sample sizes. Very fast delivery also and I’m pleased with the product even though I still don’t have a perfect match.
This is really turning out great very satisfied not done yet and haven’t sealed but definitely a better option than replacing the stones scine it in good shape just ugly color used 3 color dark buff brown tone and stone gray
The product came quickly and was as advertised. This is the correct product for old bricks! If I had to do it over again, I would but I would probably order a little more than I did.
Purchased mortar stain from Pro Mason Supply. The website was easy to navigate, view product descriptions and place an order. My package arrived in excellent condition thanks to great packaging.
I was very happy with the stain, it was easy to apply and looks amazing..
I’ve placed two orders for brick stain samples. I paid extra for rush shipping both times and I appreciate their ability to rush the order processing as well.
Very pleased with the quality/coverage of the stain samples. Will be placing an order for full-size shortly.
Great product! It tinted bricks and mortar exactly as stated on their website. I highly recommend this product to color match and/or color correct bricks and mortar.
Absolutely love this stain! Easy to use and came with easy to follow instructions, information and tips. I ordered multiple colors and blend them to look like natural stone on a solid concrete block.
Easy to blend and apply resulting in a beautified entryway.
Simple... Product delivered quickly and it did what it was supposed to do.
I havent used it yet but i just ordered 2 more quarts so i know there will be enough for my project

We were very hesistant to try a "stain" because they were only sold by the gallon in other stores and reviews said it was actually paint. The LAST thing I wanted was painted brick. This fireplace had faded and terrible brick from the propane damage. Pro Mason have sample sizes that shipped immediately. The left was dark buff. Right is brown. We loved the dark buff and purchased a quart. Ill have to update with another picture when its complete.
