Step 1. Be Safe
Before starting your demolition project, check the area for any potential dangers and keep the area clear. Make sure you have the right personal protective equipment on – steel cap boots to protect your feet in case you lose grip on the hammer, safety specs to protect your eyes from debris, earmuffs to protect your hearing, and gloves to help with grip on the hammer.
If you’re breaking up material that produces a lot of dust, have a dust mask for breathing protection. If you’re demolishing an area where you suspect there are pipes or cabling, call the free Dial Before You Dig service on 1100 in AU or beforeUdig on 0800 248 344 for NZ a couple of business days before you plan to start. This service connects with asset owners, such as sewage and electricity companies, who then forward you plans showing approximate locations of underground infrastructure. You can also hire a pipe locator or ground penetrating radar machine to determine the exact position of pipes. Talk to your local Kennards Hire branch to see which equipment is right for your project.
Step 2. The right attachment and position
Next step is to make sure you have the right attachment for the material you’re breaking up. For a concrete slab or floor, or rock or hard ground surface, a pick attachment works best. When breaking up a floor or slab, it’s best to start on an edge and work your way to the middle. Otherwise constantly stopping and cleaning up debris as it builds up in your way.
Step 3. Get the right grip
Now that you’re ready to start, position the hammer with the tip pointing down and at a slight angle away from you. Make sure your legs are about shoulder width apart and you have a strong grip on each handle, with your weight slightly forward to create firm pressure on the hammer. Using light pressure won’t give you much control and you run the risk of the hammer slipping.
Push down on the handles and the hammer will start to break the surface up.
Start breaking small bits off as you progress so that clean-up is easier and you’re not lifting heavy pieces or trying to break up large loose bits into smaller ones.
