Frequently Asked Questions


How many gallons of paint does it take to paint one mile of 4” solid line at a wet film thickness of 15 mils?
Answer: 16.5 gallons

Question: How many pounds of beads are used per gallon of paint?
Answer: This can vary but is typically 6 to 8 pounds of beads per gallon when applying standard federal spec latex.


What is the difference between a conventional air spray striping machine and an airless striping machine?
Answer: Conventional air spray stripers use air pressure to force the paint out of a pressurized vessel down the paint hose and out the paint gun. In an airless system, hydraulic pressure from a hydraulic pump draws the paint out of the non-pressurized vessel through the hose and out the gun.

Question: What size airless tips should we use for painting?
Answer: This will depend on the following main criteria:

  • How fast do I want to travel while painting?
  •  What line mil thickness requirements do I have?
  •  How many guns will I be using at once?
  •  Will the paint supply system gallon per minute output support and sustain the flow required to supply the guns long term?

Once these questions have been answered, check the size recommendation charts in the manual of the spray tip manufacturer. Contact EZ-Liner for a complimentary slide chart to calculate gallons per mile or feet per gallon requirements in association with mil thickness.

Question: What is a pressurized bead system and why should we use one?
Answer: A pressurized bead system embeds the glass spheres at a proper depth for maximum visibility and longer life.

Question: How do I know if I am getting proper bead embedment?
Answer: There are many ways to determine proper bead embedment. The internet has many different ways to visibly check the retro reflectivity, typically at night. If the test needs to be precise many government agencies as well as contractors use a device called a retroreflectometer. This device measures nighttime visibility under wet and dry conditions.

Question: How long can I store latex paint in my truck’s paint system?
Answer: When using latex traffic paint, it is important first of all to ask your traffic paint manufacturer or supplier for general guidelines on how long the paint can be stored in the tanks and lines before it will start to set up or dry out in your machine. If they can’t tell you in customer service, ask for a chemist. EZ-Liner recommends spraying paint through the system every couple of days (into a bucket) to keep the paint flowing to remain liquid. We also recommend, when storing paint in the tanks for a long period of time, that you fill the unit first so the tank walls remain wet. Do not do any maintenance such as detaching a paint gun or cleaning filters during this storage period as this will introduce either air, water, or both into the paint system and catalyze the paint drying process. If maintenance is required, wait until the end of the storage period or run paint into a bucket following this maintenance so you can immediately replace the air and water introduced to the system with paint.
