How to Use a Joint Raker

When brick or rock walls held together with mortar begin to crumble, they generally must be refinished, also called repointing, to preserve their integrity. A joint raker is a specific tool to remove crumbling jointing material without hurting the integrity of the wall itself. The raker is simple to use, and only requires a few steps, and patience, to fall in to the groove.

When repairing old houses, you will often need to repoint the walls.

Place the joint raker at the beginning of one of the creases in the wall where you desire to remove the mortar.

Begin to move the rake in one direction, pressing to remove as much mortar as you can in one swipe.

Remove the rake and insert it back in where you originally set it and repeat the fluid motion in that same area until you have removed the mortar to a depth of twice the width of the overall width of the wall.

Repeat this motion all over the entire wall, both horizontally and vertically, until you have removed all the mortar to an equal depth.

Remove any extra pieces of mortar around the joints using the soft paintbrush. Begin to repoint the wall if you desire.

Things You Will Need

  • Joint raker
  • Old Wall

Warning

  • Always wear protective goggles and gloves when using the tool, as it can cause chips of mortar to fly.
