Mortar, the binding material between bricks, can deteriorate over time due to moisture, freeze-thaw cycles, or structural shifts. Removing old, damaged mortar is a necessary step before repointing (applying new mortar).
Enter power tools - innovative solutions designed specifically to make mortar removal easier, faster, and more efficient. This comprehensive guide will delve into the world of power tools for mortar removal, empowering you with the knowledge and insights to make an informed choice for your project.
The choice of power tool depends on factors such as the mortar's hardness, the brick's material and condition, and the scale of the project. Here are some common options:
Best for: Hard mortar and dense bricks
These heavy-duty tools pack a punch with a powerful hammering mechanism and rotating drill bit. The chisel-shaped bit effectively chips away at the mortar, making them suitable for extensive and challenging removal tasks.
Best for: Soft mortar and fragile bricks
Compact and versatile, angle grinders use abrasive discs to grind away mortar. While less aggressive than rotary hammers, they are better suited for delicate work on softer surfaces.
Best for: Detail work and tight spaces
Oscillating multi-tools combine vibration and a sharp blade to cut mortar with precision. Their slim profile enables access to hard-to-reach areas, making them ideal for removing mortar around windows, door frames, and other obstacles.

Mortar removal can be a challenging but rewarding task. These humorous stories offer valuable lessons:
Story 1:
A DIY enthusiast decided to use a rotary hammer to remove mortar from an old brick wall. Excited to get started, he plugged in the tool and accidentally set the depth setting too high. With a mighty "WHACK!", the hammer shattered not only the mortar but also a portion of the brick wall.
Lesson: Always test the tool's settings on an inconspicuous area before applying it to the main surface.
Story 2:
An amateur bricklayer, eager to impress his client, used an angle grinder to remove excess mortar from a brick fireplace. He failed to wear safety glasses, and a flying piece of brick shattered against his eye.
Lesson: Eye protection is paramount when using power tools. Always wear appropriate safety gear.
Story 3:
A seasoned contractor, known for his meticulous attention to detail, meticulously removed mortar from a historic brick facade. Unbeknownst to him, there was a bee's nest hidden in the wall. As he worked, the bees emerged, swarming around the contractor and forcing him to hastily abandon his task.
Lesson: Be aware of potential hazards and inspect the work area thoroughly before starting.
