Over time you are going to find that your concrete driveway develops cracks in it, this is largely the result of the weather and the wear and tear of driving on it. In the past once you got cracks in your driveway the only way to repair them was to rip it up and pour a new surface. This is not necessary any more as the cracks can be filled and the driveway resurfaced quite easily. It is a job that you should be able to do on your own which will help to the keep the cost down.
The first thing that you are going to want to do in order to resurface your driveway is to make sure that you clean it. The driveway needs to be clean in order for the resurfacing to be effective. Using a pressure washer is the best way to make sure that you get it clean. If you have any oil stains on your driveway you will need to use a degreasing agent to get them off. It is also important that you clean out the cracks that you plan to fill. Scrape them out as best you can and then pour a small amount of bleach into the crack. After about ten minutes take your pressure washer and spray the cracks out.
In order to fill the cracks you are going to want to use a concrete dressing. For small cracks you can use a putty knife to force the dressing down into the crack, for larger ones you will find that a caulking gun works better. In either case once the cracks have been filled use a putty knife to smooth out the dressing.
Once the cracks are filled you are going to have to cover the expansion joints. These are the lines that divide the concrete of your driveway into sections. They are there so that the concrete can expand and contract as the weather changes. You need to make sure that these expansion joints remain in place so you will want to cover them with duct tape. concrete driveways sydney
The next step is to mix the concrete dressing; you will want to follow the instructions on the bag for that. You are going to need somebody to help you unless you are doing just a very small area. The concrete needs to be mixed in small batches and applied quickly. For a driveway you will need to have one person applying the concrete dressing while the other is mixing the next batch. You want to get the entire driveway covered before the dressing starts to dry.

If you are doing just a small area the best way to do it is with a trowel, for large areas a long handled squeegee is the best bet. In either case make sure that you push down hard so that you can get the concrete dressing into all of the crevices, this will make sure that you have a nice smooth surface.
