Restore and revitalize your masonry with our Hydraulic Lime Grout, a traditionally crafted solution for filling fine cracks, voids, and other imperfections in both historic and modern structures.
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.
Key Features:
- Preblended for Convenience: Our Hydraulic Lime Grout is ready to use with just the addition of water, eliminating the need for complex mixing and ensuring consistent results.
- 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.

Let customers speak for us
from 53 reviewsTook 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!
Been great on helping me with a lime mortar that I couldn't find in my area
Truly loved their Rock Stain! It took our nast colored stone and truly lifted it back to life! Will boast and promote this business every chance I get!
We have an old stone fence that was damaged, and the stone mason just used regular concrete to repair it. It didn't match the hundred years of age. I ordered a couple of different colors, and with a little mixing got it to blend. Pro Mason was extremely prompt, which I greatly appreciated. Definitely would recommend.
Great help with my lime mortar questions. Love that I can get a "sample" size container to test colors.
This absolutely is amazing! It worked beautifully on our home and freshened up the stone! Looks beautiful and clean without being heavy!
Prompt and helpful customer service, exemplary company.
The 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.
