Aside from the standard wrecking bar that we have shown above there are certain other slightly different types of bars, some developed for specific jobs:.
How you use the wrecking bar will very much depend on what you are doing. One of the most common task it will be used for is prying up floorboards. In this case you would wiggle or sometimes knock the chisel end into a gap between the boards and pull the other end down to lift a board up. In these instances you can use a small flat blade screwdriver or small pry bar to get started.
As you might guess, this requires you to lever against an adjacent floorboard in order to get the leverage to lift the other board. This can cause damage and marks which might not be a good thing, especially if you have a nice wooden floor that is permanently on show. In this case you can use another thinner piece of timber or thin piece of metal to lever against, to pry the board up and reduce the risks of potential damage to other boards.
Using a wrecking bar to lever up a floorboard but levering against small block of wood to protect other floorboards. Whether you are lifting floorboards, levering off plasterboard or prying up flooring timbers, the process of using a wrecking bar is exactly the same so the same steps below can be used regardless of the job:.
In some instances the object you are trying to lever off just wont want to budge. The best way to deal with objects is to use a combination of levering positions. Start off with the claw on one side and then move to the other side and lever from there, gently rocking the bar each time to loosen the item a bit more.
As well as using the claw end flip the bar around and use the straight or second end. Sometimes pulling the bar up as opposed to down can provide the final bit of leverage to release the timber or object you are working on.
In the example above we have demonstrated how a wrecking bar can be used to lift and lever floorboards and other timbers. As good a tool as the wrecking bar is for these jobs we also need to expand slightly on another tool that we have mentioned above — the pallet wrecking and lifting bar.
For levering up flat timbers such as pallet slats and floorboards this tool is absolutely fantastic and very easy to use. Its wide jaws will easily span 2 and even 3 inch timbers such as floor joists and other structural timbers. As above in the below demo we have used an old pallet but the principles are the same if working on floors, ceilings and other areas. As you can see from the information above, the wrecking bar is ideal for levering up floor joists, roofing timbers, floor tiles and slabs, patio slabs etc….
However a wrecking bar really comes into its own in a true demolition situation, where you just need to get on with the job and any damage caused is of no concern.
