Repointing Coverage
Coverage depends on your wall: brick size, stone pattern, joint width and depth all change how much mortar you need. Coverage is based on concentrate. 1 gallon of concentrate mixed with sand makes about 3.5-4 gallons of mortar. Use the Mortar Estimator below the video on this page to estimate what to order.

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 breathability of 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
- Made to Breathe: Unlike Portland cement, this pozzolanic lime blend lets your masonry "breathe" and flex, so moisture can move out through the joints instead of being trapped against your brick or stone.
- A Balanced, Moderate Lime: This formula is a balanced middle ground in our lime mortar lineup. It's designed to stay softer and more breathable than the brick around it, which makes it a great fit for many older homes.
- 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.
- Joint Repair: Filling cracks and gaps in worn mortar joints.
- 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.

Let customers speak for us
The masonry sealer worked great. It was easy to apply and dried perfectly.
So far, so good. It will take time.
I just tried the mortar out. Need to learn a little more about using it as what I applies turned white. Yes it was sunny and hot. I tried keeping it spritzed and ended up shading the work with tarps, but too late. I’ll try again next week since I see a cloudy day in the forecast. Marie
We took down the Wood pan line in our old home. Built in 1880. All the room is red brick. Except for this one spot that it looks like they ran out. Using pro Mason stains, I was able to make coordinate better with the rest of the room. Very happy with the results! It would have been impossible to achieve without being able to dilute and combine the stains to make multiple colors to match the variants in the original bricks.
Working out great so far
This was awesome. It mixed very well, and even though its still curing, it is very hard now. It was also fun to mix up a mortar by hand the same way they used to do back in the day.
I had my steps repointed but they were way to light and slot of cement left on the brick. These stains worked amazing. Darkened the mortar and made the bricks look new!! Love this product! I used dark buff for the mortar and mixed burgundy and dark red for my brick.
Excellent experience with all questions answered!
I purchased a type-o mortar concentrate and am very satisfied with the speed of receipt and overall quality of the final product. I particularly appreciated the clear instructions that came with the product that took any guess work out of the picture. I am a homeowner and not a professional mason but this company has allowed me to make reasonable repairs to my chimney brick work with confidence.
A very nice product, really looks great to brighten up older bricks. AAA+++
Excellent product, and helpful tips from ProMason Supply! Thank you, the lime Morter works perfectly for our historic 130 year old home, we have some major tuck pointing and repairs to the masonry to do. your company and product is very appreciated!
arrived quickly, great product
Product worked well.
My tile/mason guy convinced me to not add any color to my mortar and it drove me insane that I let him talk me out of my vision. I just put the Cream stain on my grout for my bricked floor in my mudroom and I can't begin to tell you how happy I was with the result. We ended up using it strait and didn't water it down. There were some areas that absorbed super quickly and needed a second coat. I can't wait to seal it in to protect it.
Ordered type O mortar for a historic stone foundation repair. Product was just what we needed and this is one of the only places it is available. Thanks !
