This pre-blended grout is expertly formulated for injection and compression installation with hydraulic lime and fine sand, harnessing the benefits of lime cement without the use of Portland cement. This unique composition ensures exceptional breathability, allowing moisture to escape and preventing damage caused by trapped water.

- Hydraulic Lime for Strength and Durability: Hydraulic lime provides excellent strength and durability, making this grout ideal for both historic repairs and modern construction projects.
- High Breathability for Optimal Moisture Management: The absence of Portland cement allows the grout to breathe, preventing moisture buildup and promoting the long-term health of your masonry.
- Versatile Quart & Gallon Containers: Choose the size that suits your project needs, whether you're tackling minor repairs or larger restoration efforts. Easy to handle container size.
- Five Classic Colors: Select from white, gray, light buff, dark buff, or dark red to seamlessly match the existing mortar color of your structure. It can also be mixed with cement pigments to create additional colors and can be stained after initial curing.
Ideal Applications:
- Filling hairline cracks and voids in brick, stone, and concrete masonry
- Grouting joints in historic or modern structures
- Repairing deteriorated mortar in older buildings
- Consolidating loose or crumbling masonry
- Creating a seamless and aesthetically pleasing finish for your restoration projects
Why Choose Hydraulic Lime Grout?
Unlike modern cement-based grouts, which can be too rigid and trap moisture, our Hydraulic Lime Grout allows your masonry to breathe, preventing damage caused by freeze-thaw cycles and ensuring a longer lifespan for your repairs. By using a historically accurate and breathable grout, you preserve the authenticity of your building while ensuring its continued preservation for generations to come.
Mixing Instructions:
- Gradually add water to the preblended grout and mix thoroughly.
- Continue adding water until the desired consistency is achieved, similar to that of toothpaste.
- Allow the grout to rest for a few minutes, then remix before application. Plug base of voids if using for injection purposes to avoid runout.
Safety Precautions:
- Always wear appropriate safety gear, including gloves and eye protection, when handling grout.
- Follow the manufacturer's instructions and safety guidelines for proper mixing and application.

from 191 reviewsThe 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 !
