Repointing old mortar protects against water intrusion
With excess mortar removed from the wall, it’s time to put new mortar in, that’s called re-pointing.
- Using a brush, wet the wall to ensure that mortar will bond to the mortar joint.
- Fill grout bag with mortar. Using a grout bag allows for increased accuracy and reduced mess versus using a trowel.
- Insert the tip of the grout bag into the joint and squeeze.
- Using a joint tool, insert it into the joint and slowly drag across the joint. Apply additional mortar, if needed, to ensure the joint is completely filled.
- Turn the tool sideways and scrape off any excess mortar.
