How to Lay a Flagstone Pathway | Ideas And DIY Video Guide

You look at the exterior of your home and it just simply doesn’t impress you. Maybe you want to sell your home, so you need to appeal to buyers. Or you may just want to spruce up the outside of your home and add something different without having to spend exorbitant amounts of money and without needing to hire someone else to do it for you.

You also perhaps are looking for something that can be done within the span of one weekend. Laying a flagstone pathway is the perfect way to give your home’s landscape a unique touch. Make sure that you follow instructions carefully, because if the pathway does not have a good base, the concrete can end up cracking and completely throwing off the look, according to SF Gate.

If you’re looking for flagstone pathway ideas and if you want to find out how to lay a flagstone pathway, you’ve come to the right place.

Installing a Flagstone Pathway

Here are the basic steps to laying down flagstone. You will first need to schedule a day when the weather is nice to do it, because flagstone cannot be installed when it is raining or snowing.

The first thing that you’re going to need to do is carve out the area where you want to install the pathway using twine and wood stakes. Then, dig it out at about five inches deep, as well as the length of the flagstones. Get a large container of some type, whether it be a bucket, wheelbarrow, or whatever else is suitable for you, and mix cement in it.

Then, make sure that you pour the cement where you want it in the pathway you carved out, and use a trowel to smooth it, as SF Gate instructs. Be sure to allow the cement to harden completely before you continue doing anything else.

Then, you will make a mixture of three parts sand and one part dry mortar, using water to make the mortar. You can determine the amount of water you will be using based off of whether the mortar mix will clump.

Working bit by bit, spread the mix onto the pathway, making sure to start at one end. Use a trowel to ensure that the mortar is one inch thick. Then, lay the flagstones onto the mortar, keeping spaces in between them using the style and design you would like. If there is any extra mortar in between the flagstones, scrape it off. Continue doing this until you reach the other end of the pathway. Then, allow this to dry for approximately 24 hours before you add more mortar in between the flagstones.

Once it has dried, mix mortar once again, except this time skipping the same. Then, fill a mortar bag with some of the mix, and use this bag to squeeze mortar in the gaps and joints between flagstones. Smooth anything with a rough surface out after you have let it dry for a little bit.

Clean off the surface of the stones to get rid of any residue, then allow this to dry for 24 hours.

Now you have a beautiful flagstone pathway in your yard!

There are some other designs you could implement in your flagstone pathway.

One of the easiest ways to lay a flagstone pathway is to get flagstone, use bricks as a border, and then fill the gaps in with brick. This gives a more rustic, natural look to the flagstone pathway you want to install. It also is perhaps the cheapest way to get the job done, too.

You could also use mortar to install the flagstones. The path itself will have straight, even sides and it will be very similar to a concrete one, as described by The Spruce. The stones are nearly perfect and the path is completely level.

Another idea, especially if your backyard has a pond or perhaps a pool, is to install special flagstone along the sides of it because the straight edges will give the water feature a nice look. However, you need to cover the perimeter of these stones so that UV rays don’t destroy them, and you also need to make sure that heavier materials are used to ensure that the stones don’t fall into the water.

Flagstone Pathway Cost and Materials

Like most other construction projects, the cost of laying a flagstone pathway depends largely on where you live, what type of flagstone you wish to choose, and how many square feet the area is that you wish to cover.

According to Improve Net, the average cost for flagstone per square foot is between 2 and 5 dollars. But this is simply the flagstones themselves and not the joint filler that you will choose to lay out between the flagstones.

The website also states that flagstone is typically sold in tons, which can range anywhere from $150 to nearly $1000. The biggest cost in laying flagstone is having it delivered. Overall, including the other materials, you can expect to pay anywhere between $10 and $30 per square foot of flagstone.

There are several things that you are going to need, including: stakes, twine, a shovel, cement mix, sand, a wheelbarrow (or anything else in which you can mix cement), a trowel, mortar mix, and a mortar bag. Get gloves and a dolly to transport the flagstones with, too.

You will also need to purchase some type of joint filler, if you don’t want to simply lay the stones out in your grass to create a stepping stone pathway. You can choose between different things for the joint filler, including mulch and gravel. Mulch is the cheaper option, but you will need to replace it every few years. You can also purchase bricks to use for lining the sides. The ultimate cost and precisely what materials you will need to buy depends on the way you wish to design your flagstone pathway.
