Flagstone patios make a unique design statement in your outdoor living space. Flagstone patios are made from 100% natural stone, one of the best materials for creating an amazing outdoor space. You will need to allow for some flexibility when designing your patio space.
Although their uniqueness is a great design feature, it can present challenges when working with them on a DIY project. Before adding them to your patio project, you should consider their unique colors and shapes as well as their cost.
These are some tips to help homeowners make the most of flagstone pavers when building patios.
A flagstone patio can be used for outdoor dining or as a place to relax by the firepit. Even a professionally-installed flagstone patio can need some repairs in a matter of years.
Most maintenance, including mortar and individual stone replacement, can be done by a homeowner at the weekend.
No matter the type of stone patio repair project you are undertaking, getting knee pads or a kneeler is a brilliant idea. This home improvement project involves getting close and personal contact with the pavers.

How to Install Flagstone patio?
A flagstone patio or path will boost your landscaping and impress your customers (or guests if you’re a pro).
Flagstones give a landscape design a natural feeling. Flagstone is a great alternative to boring paver blocks and cement. It will give your yard a unique look.
This article will show you how to easily install a flagstone patio or path without concrete or other special tools.
There are many ways to do the job, just like with everything else. This method is designed to achieve a balance between ease of installation, durability, and professional appearance. It will not only be simple to install, but it will also last a lifetime.
Step 1: Plan Your Patio
You should consider many things beyond the obvious ones, like patio size and placement.
Grading – Your patio must drain properly to avoid problems later. Don’t build your patio perfectly flat. It would help if you instead made it slightly angled so that water can easily drain off. This angle will allow for about 1/8″ of drop per foot. It is important to assess the landscape drainage of your property. For a better explanation, see the video.
Stone Size – The larger the stones are, the easier it will be to puzzle them together. But, larger stones can be heavier, thicker and more costly. Find the right size stone for you.
Stone Thickness – Thinner flagstones will crack under heavy loads. Thicker flagstone will be heavier and more costly. 1.5- to 2 inches of flagstone will be fine for a patio built in your backyard. Flagstone driveways should be at least 2 inches thick. If possible, go for something thicker.
Irrigation Lines – Before you build your patio, run the lines if you plan to install an irrigation system. Make sure you “call before digging” to ensure you don’t damage any lines while building your patio.
Step 2: Dig
Digging down deep enough to fit 3-4 inches of packed gravel, 1 inch of levelling material, and the thickness of pavers will be necessary. In most cases, you will need to dig about 6 inches.
You can add dirt around the patio in certain cases. However, this will require planning. Don’t build too high if the patio is near a building. This could lead to dirt reaching the siding, which can be a great way for termites to invade.
Six feet is a lot, especially if you’re building large patios. You’ll need to think about what you will do with the dirt.
Step 3: Add 3-4 inches of packed gravel base
The gravel base is essential unless you are okay with an uneven patio. The gravel base will help keep your patio flat over the long term and also support your stones to prevent them from cracking and breaking. It is the foundation of your patio. Don’t cut corners if you want a high-quality finished product.
You can add gravel 2 inches at a time. After that, you should pack it well and then add more. It can be backed down with a plate compactor or a hand tamper. It doesn’t matter what method you use; make sure it is packed well.
Building a flagstone driveway should have at least 6 inches of gravel base.
Step 4: Place 1” Leveling Sand
You don’t need to use sand as you will be walking on the layer a lot, and sand can move when you walk on it. Instead, you will want to use crushed rock with the screenings.
Decomposed GraniteGranite (DG) is the best material to use in my area. Although it looks like sand, it is much more flexible and can be walked on. It’s made up of both larger pieces of sand (1-2mm in diameter) and fine dust. This makes it similar to dirt but easier to level. Weeds won’t grow in it.
This is the last layer you need to lay stones. To ensure a flat patio, tie a mason string between stakes in the ground.
Spray the hose to make it damp, then pack it down. If necessary, level it again.
Step 5: Put the Flagstone together
Place the larger stones around the patio’s perimeter. Because smaller stones can shift and move with time, you want to use the bigger stones around the perimeter of the patio. The larger stones will hold the smaller stones in the centre.
Next, add the remaining stones to the centre of the patio, moving towards the middle. You will need to cut the stones slowly and carefully.
Here’s an idea: The more precise and consistent you make your seems, the longer it will take. This is because you have to make a lot more cuts. You can save tons of labour if you are willing to accept larger gaps. Also, it will save you money if you have fewer stones.
You can cut stones with any tool that has a diamond blade. In the video, you can see me using an angle grinder. However, there is an easier way to cut stones. I will show you how to use a concrete saw with larger diamond blades.
Step 6: Level the Flagstone
You thought you were finished? Ha! One step remains – levelling the stones.
If you don’t mind flagstone moving around while you walk, or tripping over edges, then you will need to level out each stone one by one. Many of the stones will have uneven bottoms, so you’ll need some DG (decomposed GraniteGranite) to help level them out. To get the stone to sit properly, you might have to adjust it 5-6 times. This is how it works.
A bucket of DG and a small knife are good to have on hand so that you can quickly add or subtract DG.
Start by placing a 4′-high level on each stone. This will allow you to determine how it compares to the grading that was applied to other stones. From there, you can make adjustments.
Although this step is not fun, it will give you a professional finish if taken carefully (and plenty of breaks).
Step 7: Fill in the Gaps
This is the hard part, filling in the gaps. This step can be done with any material you like. It is possible to use soil that allows you to plant moss in the gaps. You could also use more DG to keep weeds away.
No matter what you do, make sure to spray the surface with a hose so that they are locked in. Then you can enjoy all your hard work.
How to restore the flagstone patio?
You don’t have to mortar a loose piece of mortared flagstone. For a quick DIY fix to loose pavers, masonry or mortar adhesive are great options.
Step 1: Take out the loose flagstone
If the stones are difficult to remove without tools, you can pull them up with a prybar.
Step 2: Clean up dirt and mortar
For stubborn debris, use a stiff synthetic brush or a wire brush to scrub the dirt from the stones. An air hose can be used along with a brush to remove any remaining dust.
Step 3: Apply Masonry Adhesive
The stone is glued back in place using a caulk gun equipped with a tube masonry adhesive. Use adhesive beads about an inch apart or as directed on product labels to adhere to the flagstone’s bottom side. Use a flat jointer to flatten the beads.
Step 4: Apply the Joint-Repair Adhesive
Apply mortar joint-repair adhesive to the entire perimeter of the flagstone before you set it down. This makes it difficult to grab the stone without dirtying your hands and gloves. You can leave two gaps on either side for grip.
Step 5: Place the Flagstone
Place the flagstone back in its original place on the stone patio. If you missed any spots or need to fill in gaps between flagstones, apply a little more joint-repair adhesive around the perimeter. This is the time to add mortar or adhesive between stones to any areas of the patio.
Step 6: Stop using the Joint-Repair adhesive.
If you have applied too much mortar adhesive, smoothen it out with a flat jointer. Use a damp sponge to remove any excess adhesive, according to the manufacturer’s instructions. Sprinkle fine particles of sand and stone dust over the adhesive. Allow it to dry for a few days before you clean up any excess. Before you walk on the patio’s repaired areas, wait at least a few days or as long as the packaging recommends.
Flagstone Patios Ideas
There are a lot of ideas about the flagstone patio, but some of them are discussed down here:
Simple and minimalistic
Sometimes less is more. Simpler designs can make a small flagstone patio look great. Straight, well-cut stones can give your patio a clean, neat look. While appealing circular patterns will catch the eye in a subtle way, they are more attractive. You don’t need to embellish the look too much with vines and small plants.
Private Sitting Area
Your flagstone backyard patio can be used as a private area. This is a great way to combine function and charm. You can make your backyard a peaceful, tranquil space by adding a flagstone patio, a garden, comfortable chairs, and a dining table. You can enjoy a quiet read or a conversation with a friend.
Creative Flagstone Patio Designs
You can create a unique and creative flagstone patio design if you want to go outside the box. Flagstone can be used to create intricate designs, such as stars, checkerboards, and flagstone that looks like a hand or face.
Flagstone patio with a fire pit
These days, flagstone patios with fire pits seem to be all the rage. Nothing is more relaxing than sitting around a fire pit on a cool night in Cincinnati or Columbus with your friends while you read or listen to your favourite podcast or TV show.
The patio’s focal point is a stunning stone fireplace, which draws people into the area. This can brighten up any backyard with its stone walkway and a small wall.
Multi-level, stylish patio
You don’t have to limit your options to a single-level patio. A professional can design a multi-level patio that suits your needs for your Cincinnati or Columbus home. This allows for both outdoor dining and comfortable seating.
All-Natural Irregular Flagstone Patio
An all-natural patio is a great option if you are looking for something unique and stylish. Extra space is left between the stones to allow for natural grass growth. This combination adds colour to your patio, especially when it’s paired with the best flagstone.
Chic Polished Finish
A polished finish is a more modern and chic option for your flagstone patio. The flagstones will shine and sparkle in the sun when brushed and lacquered. This gives the entire backyard and patio an elegant feel.
Do you need a base 4” if you’re building a flagstone pathway or walkway?
It depends. It is necessary to prevent stones from shifting or becoming uneven. You don’t have to worry about any movement in the pathway. You can remove the base material if you only need two inches. You can also remove the base material and add two inches of decomposed GraniteGranite.
How do I obtain the materials?
A local nursery can often sell the flagstone. It would be best if you shopped around as some places may have a better selection.
At most rock yards or nurseries, you can also find the gravel base and decomposed GraniteGranite (DG). Ask them if they have DG. If they don’t. They will likely have the same thing but call it something else.
