How to DIY a Flagstone Path in Your Garden

8 Materials

This tutorial will give step by step instructions to create a cement and flagstone path in your garden.

This cement and flagstone path was fairly simple and straight forward. It was a bit laborious, but well worth the effort.

My step by step instructions are in a different location from the picture above, but the same exact method was used.

Step 1. I cleared and leveled the ground for the path. I dug 2" below grade so my path would be 2" below grade and 1" above ground to create a 3" concrete slab to set the flagstones.

Step 2. Form your path.

I used hardboard(sometimes called Euca board) cut down to 6" strips to form my path. Hardboard can purchased at home improvement stores in 4' x 8' sheets. The store kindly cut mine for me.

On the long path I used wood stakes on the outside of the hardboard to hold the hardboard in place and keep it from moving(bowing,flexing, or tipping) when I poured the cement into the path.

Step 3. Mix concrete.

I used regular concrete mix to pour my path. I mixed tow bags at a time in my wheelbarrow according to the instructions on the bag.

I mixed the cement with a flat shovel.

Step 4. Pour concrete and smooth it out.

I poured the cement into the forms and then screeded the cement with and old 2 x 4.

Screeding is the process of shimmy-ing the 2 x 4 back and forth across the cement in short quick motions to smooth it out. This process forces the rocks down and the smooth cement to the top, creating a nice smooth finish.

You could go one step further in the smoothing process and use a float to get an even smoother finish, if you're leaving your path concrete. However, I knew I would set flagstone into this cement so I didn't float the cement.

Step 5. set the flagstone

I set my flagstone while the cement was still wet but not mushy. I back-buttered all my stones with mortar because I wanted to figure out the pattern in the process and wanted a little more working time.

The last step was to "grout" my flagstones. I used mortar mix to grout my flagstone. I used the same process as grouting tile. I dumped a scoop of mortar into the seams between the flagstones and squished it into the joints with a float and then wiped the stones clean with a tile sponge and a bucket of water.

One of my goats, Bell, was very curious during the whole project.

This is a pretty simple project, but if your thinking of creating a very long or wide path, or a patio I would definitely recommend a helper or two. Cement is heavy and can get very tiring in a short time if you're working alone. So call your friends and neighbors to help with this, it'll be a lot more fun.
