Step 1: Plan Your Flagstone Path Like a Landscape Designer
Choose the Path Location
Before lifting a shovel, envision the final path. Will it wind through a flower bed or connect the patio to a firepit? Make it functional and beautiful.
Measure the Area
Whip out your tape measure and map it out. Knowing the exact length and width helps you figure out how much stone, sand, and base material you’ll need.
Think About Drainage and Traffic
Avoid low-lying areas where water pools. Flagstone works best where water can drain freely—like slightly elevated or sloped terrain. Don’t forget to factor in foot traffic too!
Step 2: Choose the Right Flagstone
What Is Flagstone?
Flagstone is a flat, natural stone ideal for walkways, patios, and outdoor paths. It’s known for its earthy colors and rough texture, which adds grip.
Types of Flagstone Materials
Common types include:
- Sandstone – Warm tones, ideal for dry climates.
- Slate – Smoother and perfect for a modern look.
- Limestone – Classic and timeless.
- Bluestone – Durable with a blue-grey hue.
For earthy, rustic appeal, explore the stunning selection of natural stone slabs.

Step 3: Gather Your Tools and Materials
Essential Tools You’ll Need
Here’s your shopping list:
- Shovel
- Wheelbarrow
- Level
- Rubber mallet
- Tape measure
- Tamper or plate compactor
Materials Checklist
- Flagstones
- Crushed gravel
- Bedding sand or mortar
- Landscape fabric
- Joint filler (sand or polymeric sand)
Grab some flagstone-friendly pavers while you’re at it.
Step 4: Prepare the Path Base
Mark the Path with Spray Paint or Rope
Outline your path using rope or landscape spray paint. Don’t rush this—get creative with curves!
Dig and Level the Area
Dig about 4–6 inches deep to make room for the base layers. Use a level to keep the surface even.
Add a Gravel Base for Drainage
Pour in 2–3 inches of crushed gravel, then compact it well. This layer promotes drainage and gives your stones a firm foundation.
For a seamless look with your patio, match your path with budget pavers.
Step 5: Lay Down the Sand or Mortar Layer
Choosing Between Sand and Mortar
If you’re going for a dry-laid path, sand is your go-to. Mortar is great for a more permanent, formal look. Either way, aim for a 1–2 inch bedding layer.
Creating a Stable Bedding Layer
Spread and level the sand or mortar evenly. Don’t skimp—it’s your path’s cushion!
Want added charm? Use sandstone veneers along the borders for a refined touch.
Step 6: Set the Flagstone in Place
Dry Fit the Stones First
Lay the stones out before final placement to get a sense of spacing and design. This is your chance to play with shapes!
Space Evenly for a Natural Look
Use a 1–2 inch gap between stones. Uneven spacing gives it a cozy, organic vibe.
Tap into Place with a Rubber Mallet
Tap each stone gently into the sand. Use a level to ensure stability.

Step 7: Fill the Gaps and Final Touches
Use Sand, Gravel, or Mortar in Gaps
Fill joints with polymeric sand, pea gravel, or mortar, depending on your preference. Sweep it in, then mist with water to set.
Compact and Sweep the Surface
Use a hand tamper to compress everything gently. Then give it a good sweeping.
Water and Set the Path
Water lightly to settle the sand and help everything lock into place.
And if you’re going for layered landscaping, consider pairing with wall stone retaining walls.
Maintenance Tips for Your Flagstone Path
Cleaning and Weed Control
Weeds love gaps. Use polymeric sand or install landscape fabric underneath to block them. Clean stones with water and mild soap.
Seasonal Care Tips
Check for loose stones after heavy rain or frost. Refill joints and re-level stones as needed.
