How to Repair a Flagstone Patio

Flagstone is a popular choice for homeowners installing flooring for a walkway or patio. Not only does the stone offer the option to create beauty with intricate patterns and stunning colours, it is also long-lasting and durable. A flagstone patio can make any size home stand out and will provide a beautiful and sturdy setting for entertaining guests, dining, or simply relaxing outside. However, exposure to elements and frequent use can lead to the most durable stones becoming discoloured or cracked, therefore requiring individual repair or complete rejuvenation. Luckily, with the correct knowledge and repair materials, homeowners can easily return their flagstone patio to its original condition.


Determine the Condition of the Patio

First, homeowners must carefully assess the flagstone patio’s condition. The entire patio surface should be examined for cracked stones that need revitalisation, loose or missing stones, and broken areas that must be replaced. After spots that require repair have been noted, the degree of breakage in each area will determine the course of action for repair.


Materials Needed for Patio Repair

A flagstone patio repair will progress smoothly when the necessary materials have been gathered beforehand.

  • A chisel and mallet for releasing broken mortar and stone

  • Mortar adhesive for securing new or loose stones

  • Replacement flagstone to fill in missing gaps

  • Sand and stone dust mix to help set stones and remove moisture

  • A garden hose for removing debris and cleaning the repaired area

  • A damp sponge or cloth to remove excess mortar

  • A stiff brush to remove debris

  • A can of compressed air to remove fine debris

  • Safety glasses and gloves to protect eyes and skin

When the correct tools and products have been obtained and gathered, a repair can be easily finished in one day of work.


Repair a Flagstone Patio

Any plants, furniture, or other items that may be damaged should be moved or covered before repair begins. Tools, products, and gear should be put in an easily accessible location to save time and make the repair process easier.

Mortar Pieces and Broken and Removed

After the area of damaged flagstone is located, a chisel is used to break the mortar surrounding the flagstone piece with the flat end of the chisel pointed in the direction of the piece to be removed. This will prevent accidental damage to any surrounding pieces that do not require repair. A rubber mallet is used to hit the top of the chisel and bury it further into the mortar. This action should be repeated as many times as necessary. After broken mortar pieces are removed, the flagstone should be broken into smaller pieces with the hammer and chisel. Any leftover pieces of mortar or stone should be removed.

Missing Stones Replaced

Once the damaged stone is removed, the area should be cleaned to prepare the area for a replacement stone using the brush and can of compressed air. If the stone is too small for the area, it will not remain level with the other stones. If it is too big, the surrounding mortar should be chiseled until the stone is of the proper size. A layer of concrete adhesive is then spread on the bottom of the stone. The corners of the stone must be covered with adhesive. After adhesive is spread on the bottom of the hole, the flagstone can be placed in its new position. Excess adhesive should be removed immediately, and the surface of the stone wiped with a damp sponge to remove excess debris.
When all new stones have been placed, a mixture of sand and stone dust should be spread around each repaired stone and left to dry overnight. When the adhesive has dried, any remaining debris should be rinsed from the area with a hose.

Finishing Touches Applied

The area should remain free of people and pets for a few days while the adhesive continues to harden. The area should be cleaned thoroughly with a flagstone cleaning agent before replacing patio furniture and resuming use of the flagstone patio.
