How to Repair Paving Stones

Paving stones are an ideal material for walkways and driveways, but because they are often in high traffic areas, they can sometimes get nicked or cracked. Using a material like glazing putty allows you the flexibility of filling any chipped away stone as it is a soft, pliable substance that dries hard. For added coverage, covering the dried putty with an acrylic paint will help it blend in with the rest of the walkway.

  1. 1

    Brush away any dust or debris on the stone with a bristle paintbrush. Make sure to brush away any bits of cracked stone that may have broken off the paving stone, as debris like this will hinder the glazing putty from drying smooth.

  2. 2

    Fill the crack or hole in the stone with glazing putty until the putty is level with the rest of the paving stone and there is a smooth, clean line between the stone and the putty.

  3. 3

    Let the putty dry for at least an hour until it becomes hard. If the putty isn't drying due to problems like damp air, blast some hot air on the putty with a hair dryer.

  4. 4

    Paint over the putty using acrylic paint in a colour that matches the stone, like brick red or slate grey. Let it dry before walking on the stones.

Tips and warnings

  • If it begins to rain outside while the putty is drying, place an upside down pot over the stone to protect it.
