Mortar Joint Grinding
Grinding is the process of removing the mortar from the joints in between the bricks. This is most often done when the mortar between the bricks is weak, water-damaged, or loose. Grinding is done prior to the tuck pointing process to allow the new mortar to adhere inside the existing mortar joint. Hand held grinders are used with diamond blades; grinding to a minimum depth of 5/8”.
Following mortar joint grinding is Tuckpointing. Tuckpointing is the process of filling the open spaces between the bricks with mortar.
