Inverted Marking Paint

Inverted Marking Paint is a great tool for land surveyors, utility workers, city governments, aerial surveying, contractors, ground surveying and much more. Marking paint is unique because it is inverted spray paint, also known as "upside down paint". Most spray paints are used by holding the can upright and pressing down the top. This can be tedious and very tiring to your finger if you need to make a lot of marking lines. Inverted spray paint can be inserted into a making wand to dispense that paint squeeze the handle of the wand. This allows the inverted marking paint to be applied easily in a broad area with less fatigue. It can be used for pavement marking, marking utilities, marking surveyor’s points, marking utilities and painting survey reference lines. We carry two of the lead names in marking paint, Aervoe survey marking paint and Krylon inverted marking paint. Both the Aervoe and Krylon marking paint are sold by the case to save you time and money. If you need a Material Safety Data Sheets (msds) please contact us and we can provide that to you.

APWA Utility Color Codes
The American Public Works Association (APWA) recommends the following guidelines be used when using marking supplies to mark underground utility line locations.

White = Proposed Excavation
Pink = Temporary Survey Markings
Red = Electric Power Lines, Cables, Conduit and Lighting Cables
Yellow = Gas, Oil, Steam, Petroleum or Gaseous Materials
Orange = Communication, Alarm or Signal Lines, Cables or Conduit
Blue = Potable Water, Water Lines
Purple = Reclaimed Water, Irrigation and Slurry Lines
Green = Sewer and Drain Lines

Why are these colors used?
Often, you will see these colors used to identify utility lines in cities and on a university campus. Sometimes city or campus utility departments will paint the tops (such as manhole lids, or storm sewer drop-inlets) of their utilities these colors before an aerial survey is flown so that the people creating the maps can identify the type of utility by color.
