Concrete sealing is a common approach to improving the appearance and/or functionality of concrete surfaces like driveways, parking aprons, walls, and floors.
The cost to apply average concrete sealing depends upon the area and condition of the surface, the type of sealant, special preparation needs, and the labor rate.
In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
