It is the easiest and the most inexpensive way of improving its visual appeal. The paint will not only give them a refreshing look, but will also protect the surface from regular wear and tear.
The first step is cleaning the surface on which the paint needs to be applied. To begin with, it has to be thoroughly cleaned to get rid of the dirt, grease, and debris, as they tend to prevent proper adhesion of the paint. If there is some old paint already existing on the steps, then it has to be removed completely with the help of a heavy duty stripper.
Allow the repaired area to dry up completely before you start with the painting job. Cover up all the adjoining areas where you do not want to apply paint.
The instructions provided by the manufacturer on the label of the container should be followed in this regard. In general, an oil-based primer requires around ten hours to dry. On the other hand, epoxy primers need much less time, and would be ready within 6 hours.
There is not much difference between painting concrete steps if they are outdoors or indoors. However, as an outdoor surface is exposed to a lot of weather elements, you must apply a coat of sealer before applying the first layer of primer. This will provide adequate resistance towards water.
Another aspect that needs to be taken care of is the weather. Check out the weather forecast to ensure that there is no precipitation for the next four days after the paint job has been completed.
