Examples of Use

• Brickwork: Applying new mortar to brick joints to improve appearance and structural integrity.
• Stone Walls: Filling and finishing joints in stone masonry to prevent water penetration.
• Historical Restoration: Repairing and restoring mortar joints in historic buildings to preserve their original appearance and function.
