Striper technology can change in the blink of an eye. These days, there are inexpensive gas-powered line stripers, specially designed spray tips (such as two spray patterns built into one tip), automatic layout systems, self-propelled systems, upgraded laser pointers, pressurized bead systems and even a floating gun kit (for bumpy parking lots). The point is, there are many walk-behind units on the market, each with its specific advantages and preferred applications. And there are many options and accessories to consider. Also, keep in mind that a line-striper is also a “general purpose” paint sprayer and can be used to paint houses, commercial buildings, etc. Manufacturers say contractors need to make sure to know exactly what they’re looking to get out of your new striping unit, and do your research before making a purchase.
