What will you do when your driveway becomes populated with pits and cracks of all sizes? The best way to fix this is to resurface the driveway. Usually, pits and cracks will develop in concrete structures if too much water was used in the mix or if it’s weakening. That said concrete resurfacing is only an option if your concrete is not cracking all the way. A concrete re-surfacer can be used to coat the slab which is usually a blend of polymer addictive’s, cement and sand that fills all the holes making the surface look uniform. Since the natural color of this mix is dark gray you should purchase enough to cover your whole driveway. A rule of thumb is a 40 pound bag for around 35 square feet of area. If you want to change the color simply add some concrete tint.

Once you have everything follow the below steps to resurface your drive way:
Step no. 1: Clean the area
Before you start resurfacing you need to strip your driveway of any sealers or paint. You also need to take a look at the weather report because temperatures should ideally be above 50 degrees for a good 8 hours and the temperature needs to be at around 20 degrees for the next 24 hours. This is why resurfacing is best carried out in the summer. Resurfacing shouldn’t take more than a day but once it is complete your driveway will look good as new.
Step no. 2: Blast dirt off the surface
Wear a pair of heavy boots with protective glasses prior to blasting off the driveway with high pressure water at 3500 psi. You can rent a gas powered washer for this task. Fit a 25 degree tip and hold it at around 8 inches from your driveway and turn it on. You need to clean the surface with slow yet even sweeps. The idea is to remove algae, mildew, and dirt from the surface.
Step no. 3: Mix up the resurface
This is a very important part of the resurfacing concrete. While your driveway is still wet mix up the required quantity of resurfacer, then mix 1 part of water with around 7 parts of resurfacer in a bucket. Use a paddle mixer attached to a drill to mix it. Then fill all the recesses with the resurfacer and smooth it with a trowel. The next step is to apply this mixture to your driveway.
Step no. 4: Filling your driveway
You will need to fill the driveway’s joints using peel and stick foam and also dampen the concrete if it has dried already. You just have 20 minutes to apply the resurfacer so without further delay pour the mixture on to your driveway. Then start spreading the resurfacer until it is around 1/8 inch thick. If you want a slip resistant finish you will need to wait for 5 minutes prior to sweeping a thick nylon bristle broom on the newly resurfaced driveway. The weather-stripping can be removed after just 20 minutes. Then wait for 6 hours prior to walking on it.
