Level Your Flooring
If an outdoor area is uneven, it's smart to consider a cement platform. To create one, you'll need to first build a concrete mold from four 2x4s, cut to size and attached together with wood screws. Next mix concrete in a tub or 5-gallon bucket using a drill and concrete-mixing attachment. Pour the concrete into the form, leveling along the top of the 2x4 with a trowel. Allow at least 24 hours to cure before removing the form with a crowbar.
