    How To Install A Mortar Joint On A Flagstone Patio

    17 December, 2010

    The joints between flagstones of a patio allow for movement of the concrete slab beneath the flagstones without causing upheavals or breaks in the stones. However, leaving the joints open would pose a danger to the bond between the slab and the stones by weakening the mortar holding the stones in place. It could also pose a danger to those using the patio, creating a tripping hazard. Filling the joints with mortar solves these issues by keeping water from between the stones, while helping to maintain the stones level with one another. To be effective, you must mix and install the mortar correctly so that it holds in place while providing the joint protection needed.

    Keep mortar from the joints when installing the flagstones by removing it during the installation process with a tuckpointing trowel to the level of the bottom of the stone. Wait 36 hours after placing the stone before mortaring the joints.

    Mix a batch of mortar in a bucket consisting of one part sand to one part cement with enough water added to create a thick, batter-like consistency. Use an electric drill with paddle bit attachment to mix the grout.


    Fill a grout bag with the mixture then close the bag opening.

    • Keep mortar from the joints when installing the flagstones by removing it during the installation process with a tuckpointing trowel to the level of the bottom of the stone.

  • Use plastic edging and string line to layout the size and shape of your patio.
  • Excavate the area, removing the earth until the area is at least 6 deep. The depth will depend on the amount of crushed limestone, the amount of sand and the type of stone used. Ask your Lang Stone sales person how deep the excavation should be. Use fine line screening stone for leveling bed.
  • Tamp the loose earth inside the excavated area.
  • Install a ground stabilization mat to keep the base material from sinking.
  • Place 3-5 of crushed limestone in the area. Keep all material damp and compacted within about 1-3 of the form board, depending on the thickness of your flagstone. Remember: your stone is only as strong as the base below it.
  • Using plastic edging, form the patio by placing the edging along the perimeter and the string line. Drive stakes every 1-2 to secure them in place. If your patio has irregular or curved edges, use a heavy vinyl or steel edging available at Lang Stone. This step is not essential, but the edging makes it easier to set the stone and retain the sand if the patio is built above grass level.
  • Put 1-1½ of sand or limestone screenings over the area for leveling. Note: for mortared joints, DO NOT level the area with sand. See below.
  • Beginning in a corner, lay flagstone in the chosen pattern by wiggling and tamping each piece in place.

    Diy Vs Contractor: It Takes An Artistic Eye

    The naturally occurring irregular shapes and colors of flagstones mean that putting together a patio is more like putting together a jigsaw puzzle. It takes time and an artistic eye to know what pieces should go together and how to shape the stones to match the desired area. If your patio has a lot of border areas, it can take skill and time to shape the stones to fit them correctly.

    One solution is to use a less defined pattern and put more space between the stones. By letting the size and shape of the stones dictate the pattern, you will have less trimming and shaping to do. This will save you time on the installation and give your patio shape a more natural look.

    Breaking stones isnt as difficult as it may sound . A light hammer tap on the edge should break off pieces fairly easily. Or you can try dropping the larger stones on a hard surface and let the pieces fall apart naturally. A chisel and hammer can assist when more precise shaping is required. The key is dont try to take off too much at one time and you should be able to shape the stones to meet your design.


    Flagstone Mortar Mix Secret Recipe

    Replacing 10 to 15% of the total volume of cement with hydrated lime usually produces optimum results. Keep in mind that the Portland cement is the glue that holds the flagstone and brick to the concrete patio.

    Years ago many recipes I looked at suggested a ratio of three parts sand to one part cement for cement mortars. I altered that recipe and always mixed my ingredients 3 parts sand to 1.5 parts cement.

    After surviving twenty-five years of brutal winter freezing temperatures, my patios look like the day they were finished. I’m convinced that my recipe is one that will work for you as well.

    I built this patio using true paver brick. The mortar between each brick is made with a rich recipe of fine sand and Portland cement. I wanted it to flow through a mortar grout bag. Hydrated lime would have been a good thing to add, but I didn’t do it on this job. The mortar, after 30 years, looks like the day it was installed. Copyright Tim Carter 2021

    However, this is not necessary as the pavers can be placed directly on the concrete. To absorb impacts and prevent fine pavers from collapsing, a mortar-free sand cushion can be laid. Patios generally need ledges to hold the pavers in place, but the 1-inch-thick pavers can act as a stabilizing perimeter for the rest of the pavers.

    Hydrated Lime & Cement Recipe

    If you decide to use the hydrated lime, you can use this recipe for the mortar:

    • three 5-gallon buckets of dry sand
    • 6.38 gallons of Portland cement
    • 1.12 gallons of hydrated lime

    I’d use medium sand. It’s available at local gravel pits or businesses that sell brick and concrete block.

    Blend these ingredients together well before adding any water to the mix. Add water slowly until you get a mixture that resembles regular bricklayers mortar.

    The consistency should be like a stiff applesauce, not runny applesauce.


    IMPORTANT TIP: Only mix as much mortar as you can use in one hour or less. If it’s hot, windy and sunny, only mix as much as you can use in 30 minutes. Do not add water to the mortar if it starts to get stiff.

    What Is Hydrated Lime

    The hydrated lime you read about is a dry fluffy powder. It’s an ultra-strong mortar that’s been used for thousands of years and still performs well.

    Lime is made by first taking limestone, a very durable rock, and heating it up in giant kilns. The rock is then crushed and is now chemically unstable.

We built the walls in this project from blue ledge stone and the flagstone patio from cut and squared bluestone.

    Stonework is a big job, so we kept our flagstone patio at a smaller, intimate size, about 300 sq. ft. This size is perfect for a small dining table, a few chairs and a barbecueall in all, a nice space for a family of four and for occasional entertaining.

    The modest size means you can complete this flagstone patio installation on weekends and in evenings without heavy professional equipment. We added the low, curved stone wall to enclose one end of the flagstone patio and provide plenty of informal seating. Thats the perfect place to position an outdoor fireplace to chase the chill on cool spring and summer evenings.

    In this article, well show you how to build handsome, durable stone walls and lay smooth, close-fitting flagstone. If you enjoy building challenges and dont mind heavy work, this projects for you. But give yourself plenty of time. Figure on about 14 full days to complete it, or about a solid month of evenings and weekends. Its an advanced project because it requires meticulous work and patience to choose the stones and fit them together.

    How Is Hydrated Lime Made

    To make the hydrated lime you’ll buy in a bag, the manufacturers add a very specific amount of water to the crushed and cooked lime and mix the two in large mechanical mixing machines. The small amount of water activates the calcium oxide in the lime but does not turn it into a paste or putty.

    Mortars that contained traditional lime were often subject to popping, pitting or disintegration if they were not carefully proportioned and mixed. Hydrated lime takes the guesswork out of mixing mortar and as such is very user-friendly.

    This is excellent hydrated lime. It’s a fine white powder and it’s going to look great on your home. CLICK THE IMAGE TO ORDER SOME RIGHT NOW.
