How to use a rock chisel for removing mortar?
Oct 22, 2025
Hey there! If you're into DIY projects or in the construction biz, you know how crucial it is to have the right tools. One tool that's super handy for removing mortar is a rock chisel. And guess what? I'm a rock chisel supplier, so I'm here to share all the ins and outs of using a rock chisel for removing mortar.
First off, let's talk about why you'd want to remove mortar in the first place. Maybe you're renovating an old building, and the mortar between the bricks has deteriorated. Or perhaps you're doing some masonry work and need to replace a damaged brick. Whatever the reason, a rock chisel can be your best friend.
So, what exactly is a rock chisel? Well, it's a tool with a sharp, pointed end that's designed to break up hard materials like rock and, you guessed it, mortar. There are different types of rock chisels, but for mortar removal, a flat - ended or a pointed chisel usually does the trick.
Now, let's get into the nitty - gritty of using a rock chisel for removing mortar.
Step 1: Safety First
Before you even pick up that chisel, safety should be your top priority. You'll need to wear some essential safety gear. Safety glasses are a must - have. Mortar chips can fly everywhere when you're chipping away, and you don't want any of those in your eyes. Ear protection is also important, especially if you're using a hammer to strike the chisel. The constant pounding can be really loud and damage your hearing over time. And don't forget about gloves. They'll protect your hands from blisters and any sharp edges on the chisel or the bricks.
Step 2: Choose the Right Chisel
As I mentioned earlier, there are different types of rock chisels. For mortar removal, a chisel with a width that matches the joint between the bricks is ideal. If the joint is narrow, a thin chisel will give you more precision. If it's wider, a broader chisel can cover more area at once.

Step 3: Prepare the Area
Before you start chipping, clean the area around the mortar joint. Remove any loose debris or dirt. This will give you a clear view of the joint and make it easier to work. You can use a brush or a vacuum cleaner to get the area nice and clean.


Step 4: Position the Chisel
Place the chisel at the edge of the mortar joint. Make sure it's angled slightly towards the mortar, not the brick. You want to focus your efforts on breaking up the mortar, not damaging the bricks. Hold the chisel firmly but not too tightly. A good grip will help you control the chisel as you strike it.
Step 5: Strike the Chisel
Now comes the fun part. Use a hammer to strike the end of the chisel. Start with light taps to get a feel for how the mortar is reacting. As you go, you can increase the force of your strikes. But be careful not to hit too hard and damage the bricks. It's all about finding that sweet spot. Keep striking the chisel along the length of the joint, moving it forward bit by bit.
Step 6: Remove the Mortar
As you break up the mortar, use a brush or a small trowel to remove the loose pieces. This will keep the joint clear and make it easier to continue chipping. If the mortar is really stubborn, you might need to use a chisel with a narrower tip to get into the smaller crevices.
Step 7: Clean Up
Once you've removed all the mortar from the joint, take a final look around. Use a brush to sweep away any remaining dust or debris. You can also use a damp cloth to wipe down the area and give it a clean finish.
Tips and Tricks
- If the mortar is really hard, you can try wetting it first. Water can soften the mortar slightly, making it easier to break up. Just spray some water on the joint and let it soak in for a few minutes before you start chipping.
- Work in small sections. It's easier to control the chisel and get a more even result when you focus on a small area at a time.
- If you're working on a large project, take breaks. Chipping away at mortar can be tiring, and you don't want to risk making mistakes due to fatigue.
