Preparation: Cleaning and Repairing the Concrete Surface
Surface preparation is essential to every concrete resurfacing project. Remove any grease, oil, stains and tree sap from the concrete surface. The surface should also be thoroughly cleaning of any loose dirt and debris. This ensures that your resurfacer adheres properly to the substrate or existing concrete. If there are any hairline cracks, spalling and flaking these will require patching up with a repairing agent.
Mixing the Concrete Resurfacer
Resurfacers allow more or less 20 minutes of working time at room temperature before it hardens. For optimum results, resurfacer should be mixed and applied one bag at a time. A 40 lbs. bag of resurfacer will require about 3 liters of water. Pour the water into a bucket prior to emptying the bag of resurfacer into it. Mix it thoroughly until it comes to a smooth consistent texture. After this, let the mixture sit for a while. Give it a last mix to make sure that it is the same consistency as syrup.
Applying the Concrete Resurface Overlay
To apply the resurfacer, simply pour a small amount on the concrete surface and spread it with a long-handled squeege or trowel. Make sure that it is spread evenly. Work on one 144 square foot segment at a time. If there are areas on the concrete that needs a second coat, let it dry for a couple of hours before applying a second coating.
Letting the Resurfacer Cure
Leave the resurfaced concrete area to cure for about 8 hours or overnight. Wait at least two to three days before exposing the area to vehicle traffic. Otherwise, make sure the it is undisturbed during the curing time. For the first two days, it should be kept slightly moist with a light misting of clean water.
Make sure to read the manufacturer’s instructions and to follow it closely throughout the process. This basic method of resurfacing is enough to cover up minor surface flaws.
