Re-mortaring brick is done through a process called repointing. It is necessary to repoint brick when the mortar becomes damaged and is loose or crumbling. It is important to repoint brick when the mortar starts showing signs of disrepair to avoid having to rebuild the brickwork entirely. A loose or crumbling mortar joint will allow water into the brickwork and will ultimately cause it to fail over time. Inspect and repoint brickwork around your home as part of your routine home maintenance.

Things You'll Need

  • Mason's hammer
  • Masonry chisel
  • Bristle brush
  • Spray bottle, with water
  • Mortar
  • Hawk
  • Pointing trowel
  • Striking tool

Chisel out the damaged mortar joints to a depth of approximately one inch by striking a masonry chisel with a mason's hammer as you guide it along the mortar joint.

Clean out the dust and debris using a stiff bristle brush. Mist the brickwork with water using a spray bottle.

Scoop mortar up onto a hawk. Add mortar to a pointing trowel from the hawk as you press the mortar into the cleaned out joints. Pack the mortar tightly into the joints to ensure that they are completely filled using the tip of the pointing trowel.

Drag a striking tool across the repaired joints to make them uniform and match the existing mortar joints.

Tips & Warnings

  • Look over your brickwork at least twice a year and make any repairs as needed to keep your brickwork in good condition.
  • Wear eye and hand protection when repointing brick.
