Restore the timeless beauty and structural integrity of your historic masonry with our PHL 3.5 Lime Mortar.
Preserving a historic building is a labor of love, whether you’re a professional mason or a homeowner dedicated to doing it right. Standard modern cement is often too rigid for older structures, trapping moisture and causing stone or brick to flake and crack over time.
Our PHL 3.5 Lime Mortar Concentrate is designed to respect the original craftsmanship of your building. It offers the same breathability and durability as traditional hydraulic lime, but in a flexible concentrate that you mix with local sand. This ensures your repair doesn't just look authentic—it functions exactly the way historic masonry was intended to.
Why PHL 3.5 is the Right Choice
- Built for Longevity: Unlike Portland cement, this pozzolanic lime blend allows your masonry to "breathe" and flex. This prevents moisture buildup and protects your walls from the damage caused by freeze-thaw cycles.
- The "Goldilocks" Strength: Rated at a 3.5 (moderate) strength, this formula is the versatile middle ground—stronger than our 2.0 for fragile brick, but more flexible than our 5.0 for high-exposure areas.
- Multiple Sizes Available: Choose from quart, gallon, 5-gallon, and bulk pallet quantities to match the scale of your job, from minor touch-ups to major restorations.
- Visual Accuracy: Choose from White, Gray, Light Buff, Dark Buff, or Dark Red to get a seamless match with your existing joints. Color packs are packaged separately with the mortar so you can add less pigment while mixing to adjust the shade of the mortar.
- User-Friendly: We’ve stripped away the complexity. Just follow the mixing ratios for sand and water to get a smooth, workable consistency that’s ready for the trowel.
Best Uses
- Repointing: Filling in aged or receding joints in historic brick and stone.
- Structural Health: Fixing cracks and gaps to stop water infiltration.
- Heritage Restoration: Maintaining the aesthetic and physical integrity of buildings originally constructed with lime-based mortars.
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. Mortar is ready to use right away.
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
Pro Mason Supply is a dream to work with. I've ordered Brick Stain several times and it has arrived carefully packaged. The Stain works very well and lasts. I will always use Pro Mason products! Highly recommend
This is my second order. My mason liked the stain I ordered and it looks great.
Great paint. It’s nice that you can order in small sizes to be sure you purchase the correct color. Delivery was great.
This brick stain was so easy to apply and looks great! Shipping was fast and customer service was great.
Very responsive to my emails. Speedy delivery. The red mortar worked well. Thanks!
So happy I found ProMason Supply. We have an 1800’s brick farmhouse that needs some love. The lime mortar concentrate works beautifully for it.
Ordered several items to work on the foundation on my historic home. Items were well packaged, delivered quickly and exactly what I had ordered. Recommend this company if you need specialized mortar mixes.
I love this company! I was determined to lighten the mortar on the brick floor in my sunroom. I sampled a stain from a well-known paint store, but what was supposed to be a stain looked too much like ordinary paint. Then, I went on the hunt. I found ProMason Supply on Google. First, I ordered two samples of water-based stain hoping one would be just right, but it was the mixing of the two (Cream and Dark Buff) that got me the color I wanted. ProMason wasted no time getting the quart-size cans to me that I needed to get the job done: simple ordering, fast shipping. I’m an amateur and close inspection shows it😊, but it was a days-long project well worth my time. See the before and after pics. The room looks so much bigger and brighter. Thank you, ProMason!
