It is most economically friendly to repaint your parking lot at least once per year. If you wait too long, your lines may fade away entirely and the cost for doing a new layout of the lines is quite higher than just having a regular maintenance program.
Once the snow melts, the parking lots must be swept to remove gravel, dirt and debris before we can paint. Once that is done, we can come in and paint the lines! Any asphalt crack filling, seal coating and repair should be done before the line painting gets started.
