Flagstone paths and walkways make a striking addition to the exterior of any home. They give your outdoor space a more natural quality than concrete or asphalt that is as sturdy as it is aesthetically pleasing. However, if you've grown bored with the tan or light colour of your flagstones or if you find their natural shade has faded over time, you can change or enhance their colour manually. While the results aren't permanent, they tend to last for around two years.

Put on your rubber gloves. Mix 1 qt. muriatic acid with 2 gallons of water in a bucket. Dip your scrub brush into the mixture and scrub each individual flagstone vigorously. Rinse well with clean water and allow each flagstone to dry for 24 hours.

Fill a bucket with a solution of a mild concrete stain mixed with water in a 1:1 ratio. Pour the mixture into your sprayer and spray each flagstone individually, working the stain in with a broom. Allow each flagstone to dry completely.

Rinse out your bucket and mix 1 cup of baking soda with 1 gallon of water in your bucket. Dip your mop in the mixture and wipe down each flagstone, neutralising the mild acid on the stones.

Pour your sealer into a paint roller pan and dip your paint roller in it. Coat each flagstone with a thin coat of sealer. Allow the sealer to dry and add a second coat.
